MX5 NA Miata - How to build your own Cold Air Intake and heat shield 

Wow, I didn't expect it to make such an audible difference.

You're literally teaching me how to restore my 91 miata that I bought in 1999. She's getting a FULL overhaul plus mods. Thanks for everything : ) 👍👍

Yay, a new video. I'm always stunned how rust-free and clean your Miata is.

Dude it’s 3 am and I’m not signed into RU-vid on my phone, but I had to sign in so I could give this video a like. Out of all the videos I’ve seen you’ve broken it down the most and made it easy to find and understand. Thank you so much!

This video is really well made! The circles and zooming in makes it so much easier to see what you're doing!

I love those memes in between... Especialy with dropping the bolt and when you revved it with the new filter and his head went bigger.. hahahaha small details like that make the video enjoyable

I do like that deep induction sound... probably will try this out myself. Thank you!

Hey, I just bought a 97 miata , I really like your how to videos keep up the good work.

Vanaf nu : 100 procent mijn favoriete RU-vid kanaal. Altijd goede instructies!

Worth the wait thank you for making such easy to follow along videos.

wow the difference in sound is much bigger than i was expecting! Nice ;-)

Perfect level of improvement. And very good and useful conclusions.

Awesome video! I loved the little meme faces you added in, to me the sound after the cold Intake is installed it sounds like a 4AGE from an AE86

Very good video, thanks! This is gonna help loads of people out for sure. I'm still using the airbox at the moment so will have to try this soon :-)

Looks great and sounds good! You keep giving me things to do to my wife's Miata. Thanks for the video.

Great Miata content man! I love watching your videos!

Thanks for the great video. i will be doing this as my first mod. just got the car and i love it.

Soo clean look, love it!

Love these videos. I would love to take my 97 1.8 NA over to the Netherlands some time from Ireland as my partner's family lives there. Maybe I'll be sporting a cold air intake like this when I get round to it! Keep it up :)

Like you said, I bet it didn't make your Miata THAT much faster at all. However, the sound difference is INCREDIBLE! It went from sounding like a stock 4 banger grocery getter (basically just like my Miata sounds) to something that actually some real grunt to it. Great job with the tutorial video. Earned a sub from me bud. Keep up the good work! I also like your stickers too btw. I might just snag one off of you!

Very nice video with great editing! Very clear presentation, good fun and excellent English (veel beter dan mijn Nederlands - dank U Google!). Very enjoyable! Rob (in Switzerland)

Hey cool. I just instaled & rerouted my cold air intake on my 99 miata love the new roar sound only problem is to get the roar sound & sound bad ass u have to get more into the throttle which uses more fuel lol but its worth it I found my new u tube video now u got me wanting to do more the M flush is next only hear the lifter ticking when. I floor it so going to try it out

I lovd this guy! All his stuff is awesome and DIY

Its so satisfying hearing the engine get throaty being able to breathe more air. It never gets old. But we do need to take care of our own bodies and stop polluting the air as we can keep breathing deep throaty breathes. Not like darth vader but you know what I mean. Most of you anyways.

thanks for the before and after audio!

It may be a good future mod to extend the heat shield to protect the brake master cylinder, makes you track-ready that way and reduces risk of fires like the one that happened to AdamLZ

love these video's, hope to do these kind of things myself. Only thing that stops me from doing it is money, As a student in Belgium its very expensive to own a car. Insurance is very high, even for an mx5. One day i'll be able to do this and i can't wait for that moment to come. :)

Great video. On my list of things to do.

My favorite new RU-vid channel

Nice videos bro. Keep up the hard work

Try trimming one side of the U shorter to accommodate the difference. I'm sure a cleaner look will be achieved. And maybe a slight/slight powergain may be achieved on the butt dyno. Thanks❤

Sounds fantastic!

awesome difference. really useful additional info'

It has a deeper sounding note, I like.

Nice video! Keep up the great work:)

Lol the little meme when you’re revving the car 😂 but you should definitely sell the mounts! Maybe $65?

My understanding is that it will note affect power by much at all... I then i heard the sound change! I would happily lose a HP or two for that sound.

Nice. I will have to try this on my 1.8 95

Tof filmpje weer! Ga zo door!

Great mod! I'll be doing something similar myself. Predictably, people are bashing it of course, to which I would say: it may add or lose 1% or 2 % or 3% of power at various points in the rev range. So what? You will never, ever feel a 1%, 2%or 3% difference in performance while you're driving. Miata's are all about how they feel to drive, NOT ultimate performance- and that feel-factor was one of Mazda's key design priorities. Sound is a huge factor in that. If your Miata sounds nice, it will feel better to drive. Mine has felt way better, and is far more fun to drive, since I fitted an aftermarket exhaust system. Is it any faster? I doubt it. Does it sound nicer? Hell yeah! Any performance gains or losses from a filter arrangement like this will be so negligible as to be imperceptible, but it will transform the way the car FEELS to drive, and that's what Miatas are all about. As for cold air/ hot air...it's as far away from the hot exhaust as it can get, and without detailed studies of airflow under Miata bonnets, that's good enough. The stock box draws air from a tiny gap between the bonnet and fender, this draws it from the gap between the headlamp, fender and bonnet, from the front of the car, from the airflow through the bay etc etc. If someone's ever analysed the airflow in all those areas, I've never seen the studies. Anyway, TSI's and/ or a vented headlamp cover will definitely improve things, as you say. Will ANY of it make you feel any difference in performance, or result in anything more than infinitesimal gains or losses of power? Of course not! :-) Great channel, man, great mods and I'm thoroughly enjoying what you do to your Mazda. You have already inspired me to go LED with my interior lights and number-plate lights, so keep up the good work, and please keep the mods and videos coming!

Please don't tell me you've stopped making videos, this was genuinely my favourite 'working on mx5' video channel on RU-vid. I hope all is okay and I hope to see you again in another video! 💙

Hey mate!!! I am that josh_miata!! I just say that I read somewhere, like nutz or miataturbo.net I dont really matter on this as I am running mafless, with me221. That is the best mod, all this fantasy things are nice when you open the bonnet at a meet, but not between technicians. Also, appart from that your car is running fine, the mk1 1.6 maf is "gate" maf, if a japanese engineer designed and decided a position, I put in doubt that you make it better than them. But anyway cool mod and merry xmas dude, enjoy that nice toy!

im done for already install they was fit my budget thanks u

Great video!! can you please share again the Heat shield / mounting bracket measurements Pleaseeee

dyam i want miata so bad right now just because of this video

Here's a little tip for you. Use a nut driver to tighten the hose clamps. It is much easier to tighten them without the slippage you get from a screwdriver.

The air flow meter is supposed to be mounted horizontal so gravity doesn't affect the flap

Thank you so much for all of your content! I recently purchased a 1995 Miata and I've been using your videos to help with my DIY improvements! Do you have a new link for the Heat shield / mounting bracket measurements? The current link in the description is broken

Echt bruut! Klinkt super Nice! 😁

For some reason, I thought yours was a 1.8...not sure why...doesn't really matter, lol. Anyways, that mod looks great and sounds even better...job well done! Now you can get a scooped headlight cover to ram air into your filter for even more HP...that you probably won't feel...lol.

Your buddy who told you not to rotate the mass airflow sensor was thinking of the old mass air meters like on the Toyota’s..... they had a mechanical flapper door inside with a potentiometer mounted on the end... those need to be mounted right side up. Your Miata has a fully electronic airflow meter

Hey man love your videos and how at home friendly they are!! Do you know of any issues with messing with the air fuel ration by adding the filter and the kinks in tubing?

Nice job!

Looking at doing this to my Miata, could I get a rough measurement of how long and wide the heat shield is? Awesome video as well, so professional and such a clean install!

Hi miatamods!! I like this cool mod!! Sounds great and I'll do the same to my '90 na, the only doubt I have is how can this affect to the AFM in vertical position, don't you think the bearings of the fan could be damaged?? How long are u using it?? Any problems?? Thanks

Fantastic. You really got me thinking I should build one myself. The pre-build are just too expensive or doesn't meet my expactations. Thanks

@miatamods sounds nice man. Im not sure how necessary it would be but have you thought about getting one of those vented headlight covers?

Very informative video! Good work. Where did you purchase the aluminium connectors?

Nice work! I will be installing this air intake on my best friend's '93 Miata. Where did you get the 75mm aluminum connectors? Thx

anyone else know where to get 75mm hose joiners, I cant find any online and the home depot near me doesn't have it.

While I'm not sure it's a huge cost savings when you figure in the time, I love the details. I'm not sure a whole lot of folks have a sheet metal bender either, still it's pretty cool.

Funny with RU-vids new advert placement below the video, how there are intake kits for MX5's for sale from £111 to £430. While showing a video of a DIY cheap mod

its looks really really great , i only see 1 problem , i run a Front top strut bar so it wouldnt fit :/ , but this looks really clean and cheap because for mk1's you see cold air intakes above 150 €

Hi! Love your videos and your work 🙏🏻 Where did you get the adapter plate?

Darn it, now I want to do this too. I've got cruise control so I'd have to ditch that to make room. It doesn't work anyway. :)

What size 180° silicone hose would you recommend? I’d like to buy one, and make as little cuts as possible, to use as little connectors as possible. Thanks

Awesome video man! Only question is I have a strut tower bar, the intake would be in the way of that, if you install one in the future id love a video on how you moved the intake for the tower bar to be installed correctly

WTF man this sounds dope, I want this on my NBFL too! Is it mostly the same?

good job

You should produce and sell the heat shields, I dont have the tools to make one but I'd buy one already made :)

hey great videos. are you comming back?

Hello, what is the distance from centre to centre of that silicone U bend you got please.

That’s dope

know any links for a mounting bracket for the MAF that isnt necessarily a heat shield as well?

@MiataMods, do you have links to the Silicone hoses and aluminum connectors?

Impressive!

Hey miatamods, may i ask that where do you get the connector from?

If you fit a larger AFM from a Rx7 you will gain a little more bhp

Where did you get that adapter plate from? I'm definitely going to do this!!

I'm gonna do something like this on my Scion TC

Hey doesn't the afm sensor be in the original (horizontal) position becouse of the flap inside ?

Would you be able to help me with making an air intake for 2014 miata? Thanks

The AFM on a mk2 is far less restrictive. Might be a good swap if possible

does it matter what type of metal the metal sheet is for the heat shield?

I cant find the 75mm aluminum connectors anywhere? please help

I love these cold air intakes. They tell me which Miatas not to buy. I think you probably know what you're doing, but when I open the hood and see crap like this the car usually runs rough, blows smoke, and/or leaks oil.

Wouldn't rotating the afm give a different airflow reading?

I cant open link about heat shield... something about "pirvat things". Can someone help ? Im form Poland, and maybe that's a problem. IDK...

where did you buy the aluminum connectors from, is there any chance you have a link?

where did you get the afm gasket from? Thanks!

I don't know if it's a dumb question but does it fit an nbfl?

Where’s the best place to get the 75mm aluminum Connecter?

@MiataMods Where did you get the AFM adapter plate?

It's almost prooven that it sound better but you loose some of the lower RPM power in return of gaining higher RPM power (less niutonometers but more max speed). I have a plan of doing some dyno tests before and after such change and compare results.

Hey bro ia their a link for 90 degree 76 mm silicone hoses

Ive heard cold air intakes add horse power. With that being said how much horse power do you think you gained from this mod?

whoo dutchies unite!

Where can I found that square to circle adapter? Or did you build it ?

Can anyone help me find not overpriced silicone tubes for the intake ??? Thanks

Can I buy the shield/mountain bracket and adapter from you?
