I have the part #400019 and it says HA-1199 on the box. Correct according to K&N. The filter just lays in there like a floppy dildo and the edges hardly seal at all. The top of the air box also won't go down because the prongs(?) hit the K&N.

The stock filter goes in just fine WTF!!!!!!!!!!!!!!!!!!

Might be the right box, but wrong filter..

Wife has a K&N filter on her car, and its a pain in the ass to get all the planets to line up so there is universal peace long enough for my to get the top of the intake housing back on. :roll:

I had the same problem. I ran a small bead of the grease provided in the channel the air filter lays in and then slowly bolted the top down until it was flush. I wasn't very pleased with K&N's quality...should have dropped in like factory IMO.

What a bunch of shit. They didn't even give me any grease, will any high quality do? Do you feel confident there are no open gaps?

Guys, The instruction were kinda interesting/confusing, but... You have to remove the O-ring from the airbox... NOT the airbox lid... Then the K&N drops into place nicely. Greasing the bead area on the airbox competes the seal for the filter. It took me a while to figure it out at first...

OH, sweet! Thank you, I was about to trash it.

Good point MilHi, I had forgot about that. Even after I had removed the O-ring the lid still didn't want to sit flush like factory.
