How to fix and repair the stripped plastic threads of the stock air cleaner air box by drilling new holes and placing new metal bolts to secure the lid, and How to modify the stock air box to improve intake air flow.
Chevrolet Silverado Stock Airbox Mod
A modified Stock AirBox with an aftermarket replacement filter is better performing than a "COLD AIR" intake.

This trick works for most Chevrolet Silverado GMC Sierra GM Truck and SUVs, and probably as well for newer 2019 and 2020 2021 Silverado Sierras

I’ve done this exact mod years ago with stainless hardware with wing nuts! You’re the only other one I seen do this 👍👍👍

I did something like this back when I was using the stock intake resonator and airbox on my civic and was looking for an example to show my friend for his truck I'm helping build, this is perfect

@Chief6067 Год назад

I have the same problem with my air box A couple Screw holes are stripped out, so I’m gonna try your solution. Also going to try the air box mod for more air too Thanks for posting

Hello what did you with valve cover vent when you install the airaid jr tube.

I have a crankcase evac system, they go to the exhaust

Dam I can’t find this part i bought my 2008 silverado and the air box came with like a mini air intake on the side of it and I can’t find it it’s like a little filter

@fs4538 Год назад

So is the foam important? Mine is disintegrating and has a huge opening on top. I'm assuming it'll suck in air from under the hood, which might be hotter? Learning.

@jdlawless_fuel1416 Год назад

Yeah it's just insulation

@marksman4004 7 месяцев назад

I need to do that

@jasonnellis3566 Год назад

Hello is it better to modify air the way you did or drill 1/2 holes in the bottom. Thnx

@BadAssEngineering Год назад

I rather have cold air from the wheel well than hot air from the engine bay

@jasonnellis3566 Год назад

@@BadAssEngineering yes cold air is better. Thnx

K&N drop in filter

@twrh6067 7 месяцев назад

What is the size of the screw?

@BadAssEngineering 7 месяцев назад

One that fits, but I think I used 1/4"

@tylerc5077 2 года назад

i just took the whole peice off instead of cutting it

*What whole piece? The one that goes through the fender?*

The fancy intake filters are a pain in the ass to get and a pain in the ass to clean and oil. Leave the original alone. Take it from a buyers side. I wish the guy I bought my truck from kept the original air intake. Now I have to look for air filters for it online. I roll my eyes at stupidity🙄. At least if you put one in go with K&N something more readily available and not Valiant like wtf. Use some common sense. It’s a shit intake if you ask me.

Same happened with a Scion tC I had years ago. It had an injen CAI on it when I bought it but they didn't keep the OEM airbox. I ended up getting the full air filter assembly/tubes from a pick-n-pull for $20. As cool as the induction sound is, there's no denying the fact that the car was a bit quicker and better throttle response with the OEM parts

@joshuaraffensperger3592 Год назад

Won’t improve squat. If you want more air replace the 5.3 intake with a 6.2 intake it bolts right up. The 6.2 intake has a larger diameter inlet.

@BadAssEngineering Год назад

Same sized air filter and not improving throttle body means no flow improvement

@timothynorris7248 Год назад

Yep throttle body comes first I shaved my bottom lip off throttle body you can take plate out and all apart to clean but when put back together just relearn throttle position and calibration of throttle plate.

@239seth 11 месяцев назад

It work work on 99-06 model I don’t think, I havnt seen anyone do that on those years just 2015+, I’ve seen tbss intake manifolds for the 99-06.

@thunderbolt5354 3 года назад

Pal it will not do anything for a stock engine ! Factory opening is more than adequate !

@BadAssEngineering 3 года назад

If I was going to take it down and fix it, there was no point on leaving it stock. Nothing is sacred, chop 'em all

@Anubis78250 2 года назад

I would tend to agree, except that my air box is already opened up like this from the factory. So it would seem that GM decided it was a good idea at some point.

@cmscms123456 2 года назад

Not quite

@cmscms123456 2 года назад

The air filter has 4 times the area of flow, compared to the air inlet hole... Simple math tells you the air inlet hole is a restriction.

@Anubis78250 2 года назад

@@cmscms123456 Simple math isn't enough. The reason the filter is larger is because it has more restriction. You would need to compare the flow rate of the filter to the opening, not it's size.
