4:06 I would suggest placing the sticker somewhere visible under the hood, firewall, shock tower, etc. In CA, CARB EO stickers should be visible during an inspection, without it, you may have to argue your added on part, YMMV. Great comparison video!!
Something to note for anyone looking into these inlets - The Cobb inlet's BPV bung is slightly longer than the GrimmSpeed inlet's BPV bung. This can cause some BPV fitment issues depending on what charge pipe/BPV setup you're running. I was running the Cobb inlet, GrimmSpeed BPV, and OEM charge pipe and found out the the BPV was sitting crooked due to the Cobb inlet's longer bung. It wasn't extremely crooked, but enough to make me swap back to the OEM BPV for now and avoid any potential leaks. I chatted with GrimmSpeed about this and confirmed that the fitment is extremely tight with their BPV and inlet together, so the Cobb inlet's bung being slightly longer was enough to cause interference. Running a non-OEM charge pipe might help with this, but I haven't tested it yet. Regardless, I believe these are both solid options for aftermarket inlets. Just wanted to give a heads up for anyone that may be planning to run a setup similar to mine. UPDATE: I am currently running GrimmSpeed BPV and Cobb inlet with a Cobb TMIC/charge pipe kit which has a silicone coupler for the BPV/inlet/charge pipe connection. I was able to trim the BPV side of the coupler enough to make everything fit perfectly.
@@montano171 I’m now running a Cobb charge pipe with a silicone coupler, and the fitment is better. Not perfect, but better. I ran the GrimmSpeed BPV with the OEM charge pipe for a few weeks without issues, but I was uncomfortable knowing how crooked the BPV was sitting, so I took it out. I could see the metal-on-metal wear on both the BPV and the turbo inlet from where they were interfering with each other. YMMV, but any time there’s metal-on-metal where it shouldn’t be, I wouldn’t recommend it.
I just installed the same setup as u Grimmspeed bpv and Cobb inlet. Did ur dam go down and were u getting consistent feedback and fine knock learn. My dam is currently at .250??
Thanks for the video. Cobb has hit the mark so far with previous modifications. So I feel confident about going with cobb for the turbo inlet. Any advice for boost controller's?
I always hate giving cobb my money but unfortunately my grimmspeed order had been backordered for several months. The grimmspeed seems to be a better, more finished design.
Thanks for the review. Just installed the Cobb and finally broke my oem one after messing with it so much (caused by separate bpv and charge pipe installs -- I think the breakage of the oem part is self-inflicted).
Currently everyone we know that has done it including us has a gap towards the front of the Spoiler. The trunk has a natural curve unlike the VA WRX. We are hoping to come up with a solution
Why's the vid all blurry? I like these comparison vids. Very helpful. I'd say that the Cobb is just better all-around and better designed, more practical.
Can you run the cobb inlet with grimmspeed bpv? I have a 2020 wrx with grimmspeed intake and bpv. Leaning towards the cobb inlet. Having a hard time deciding lol
i can see on this vid the grimmspeed is much better quality forging & machining. plus cobb changing the size will disrupt the stock map, meaning you would require a tune! and i bet those inserts for the ports are plastic, so another way they cut manufacturing costs yet jack the price up! I'd choose grimmspeed over cobb for ANY parts on my subie!!!
The Grimmspeed inlet is very nice! Can't go wrong with that choice. However neither one requires a tune and the inserts for the ports on the Cobb inlet appear to be billet aluminum.
Is this upgrade a preventative/reliability upgrade over the stock plastic? Or are there any potential power benefits from the smoother airflow these would theoretically provide?
It’s cool that Cobb got theirs approved but does it really matter? Isn’t the GS inlet basically a more durable factory replacement? I forget if tune is needed after installing it (stock or not).
They will both do relatively the same thing. And neither requires a tune. The cobb one has some advantages over the grimmspeed one for someone planning to utilize those advantages, but at a slightly higher price.
@@ImportImageRacing I got that part I just wanted to know if having the part approved by emissions group really meant anything for the exact reasons you listed
So have they had any issues with the Cobb Inlet on the 17-21s leaking at the PCV hose inlet that gets I guess kinda rigged down by a clamp connection, so did they have leaking there that they added the clamp?
I recently had my engine rebuilt and as part of it I upgraded to the Cobb Turbo inlet to mate with a new turbo, anyways, I'm running the Grimspeed ebcs with this part as well, so you'll be fine.
They work on any standard size turbo. Ie boost lab. Oem. Forced performance. Tomioka. If you go wild down the road and do an ets rotated kit it will not work. But you can achieve 550hp on a boost lab so you should be just fine!

While a tune is not “required” for this turbo inlet upgrade, some performance gains will be left on the table unless coupled with a tune. But replacing your OEM turbo inlet with a piece like this is always a great idea!
They don't advertise it but if it fits the stock one it will fit the Grimmspeed EBCS, you will just need to reuse the screws that come with the grimmspeed ebcs.
It does not. The 2022 wrx already comes factory now with a cast inlet so you don't have to worry about it breaking. I'm sure there will still be upgrades soon!
