Yeah, I tried it with teh 10mm bolts loosened as well as the torx screws that held the cf intake channel in.

I stopped by the shop that did my exhaust installation and asked for their opinion - when I popped the hood, the intake housing cover was resting perfectly on the air duct, probably held down by the hood. Spoke with them and they didn't feel having it latch on or not was going to make any difference.

Also did some sound comparisons to other intakes on youtube, and the engine noise change from stock to this one sounds the same as the change I noticed in my cabin, so we're all good. Thanks for the help everyone!

Does anyone w/ this intake have the K&N Air filter part or model number? I'm nearing 20K on my intake, and I just want to replace the filter than clean/oil it.

Does the performance intake have the carbon filter? It looks like it comes with the K&N filter and a carbon filter delete + a little more air. Is that all it is?

Great DIY! Might as well clean the MAF Sensor since it's accessible. It will boost MPG. Just cleaned it for my other ride and I can see the difference.

Thanks for the DIY. I installed the intake in 1 hour. I am also getting the exhaust installed this weekend.

Hi, does the kit include the rear filter housing (grey filter) when the performance kit was purchased? If not can it be bought individually?

Fantastic DIY! Was very helpful. I have a couple thoughts based on just having done this on my car:

1. The little plastic screw that holds the wire cover/bonnet seal in place is actually the male part of a two piece expanding rivet. You need to take the female part out of the old piece and transfer it to the new piece. Then the screw will have something to go into.

2. leave the snorkle off until you get the airbox lid screwed down, and leave out the two 10mm bolts too. You need to be able to see into the airbox to get the lid lined up properly in the grooves, and you will need to be able to work the whole assembly around to get the snorkle in place. I found it best to clip that rear latch in place and then work forward getting the lid in the grooves and the screws in.

3. Finally, once the snorkle is screwed in, insert and tighten the two 10mm bolts.


Final thought - I'm generally not wild about using oiled filters on engines with MAFs. But in this case, keeping the charcoal filter in place seems to eliminate the potential of contaminating the MAF sensor. Plus adding a little extra air filtration for anything that gets through the K&N.

I did the Performance Exhaust at the same time and the increase in sound is just perfect. Not too loud, no droning, but also no more feeble whine at low rpms. Even if it doesn't make the car faster, it certainly sounds faster!

Excellent write-up. I'm surprised that the Perf Intake uses a flat filter like the US OEM. I thought it would be pretty much identical to the Euro intake with the addition of the carbon fiber part.

+1 I'm surprised it's flat as well.

I'd personally go with the euro airbox to this.

Sorry to revive an old thread, adding to this comment - that is a great idea! I followed OEM instructions and attached the top cover into the snorkel first, then went to clip the back in... I ended up snapping the end of the "U" on the clips off. I tried to wiggle & pull it off once it was in there fully and it seems to be ok with just an "L" shaped clip now but I was pretty disappointed at that. Also did the same as your #1, had to drill out the screw. The entire thing just spun in place on mine, the expanding rivet had no grab on the parts it was holding together except to keep them from coming apart vertically...

Excellent DIY btw!
