NB: Be sure you line up the grooves of the cover with the tongue that runs along the edge of the bottom, especially at the left (the grille intake duct) when seating the cover, or the screws will miss their seats. It took a couple of tries before I got it seated right.

The flutter won't happen if the box is completely fitted. Sometimes when you put it on, there's a space (tiny) between the front snorkle and inner bend where the airbox meet that the grove isn't clicked in. You'll see that the box has a very small groove for this purpose, but it's trickly to lock it in perfectly.

HAHAHAHAHA Yup.....that was me. The idiot who did NOT wait till the engine cooled down. I was drenched after the install and had to shower.

Going for a drive later to test this baby out!!!!

It's not clear from the included instructions if pre-oiling is necessary.
Anyone? I ordered the aFe oiled version, but it didn't come in a plastic bag inside the box, as with other oiled filters I ordered in the past. It doesn't feel terribly oily to the touch either. Thoughts?

No worries... mine was oiled. #1, it's more blue than grey, and #2, some of the oil seeped out onto the instructions (making them blue), sooooo... all is well in my world. And thanks for the DIY... it made my life a LOT easier!!!

There are a lot of variables. Mainly speed. But it could be figured out in certain scenarios. Ive actually had water come up from #1 when i drive after rain or something. it almost seems like its more of an exit to keep air flowing but im sure it does suck in when that engine wants air. I have yet to take it all apart to see

many thanks to the OP and BADFISH for the instructions! It made the job so much easier. Special thanks to Badfish for the 25 size Torx and loosening the larger hose clamp instead of the smaller one...worked like a charm!

How often does one need to replace this filter?

I notice a big dry leaf got into the duct. I could grab most of it out but it broke and some of it is stuck in. Is it worth opening the filter box to get the rest out ?

Nice writeup - provides confidence to know that this is drop-dead simple and quick. I spent a little extra cleaning all the different intake tubing since it looked like a leaf & sand storm had blown threw.

I simply went with a new stock filter. $23: acceleration sounds more visceral and aggressive; MPGs have soared to where I can't remember the last fill up; +11.3 shp (Seat Horse Power measured via butt-dyno™). Seriously though, for that price I'll replace this about twice per year and have the confidence that I'm properly filtering what goes in my out-of-warranty engine.

Great DIY, thanks! I had to go back and reinstall the cover after missing step 7 and also found it easier to disconnect the rubber pipe at both ends. FWIW, my '11 also required a Torx 25 instead of a 20.

Great write up to both the OP and Badfish. The only thing I would add is that when you're replacing the airbox cover, you need to apply a bit of pressure until you hear audible "clicks" as the cover seats firmly over the box. I think there were about two or three clicks in different areas as I went around.

Also, as one of the other posters noted, the edges of the plastic pieces are quite sharp so you might cut yourself if you aren't careful.

Just did this, for sure not more then 12 mins including finding my t25. Went for little drive after, nice little increase in sound, think it's just what I need in combination with my acm oem exhaust mod. Old filter was pretty dirty, haven't changed it ever and cars got 54k miles.

just changed my air filter to a k&n but it seems that the filter is smaller than the oem and its fitting very loosely causing a possible gap of unfiltered air. i wedged a bottle cap between the filter and the button that holds the filter in place to tighten it up for now. anyone else have this problem?
