Post changing air filter

I want to change the air filter on my 97 GT. Looking for a K&N filter part number that'll fit.
I popped the 2 clips on the air box but could not lift the cover because the air intake pipe to the throttle body still still attached. Is there a trick to this or do I have to remove the air intake pipe (4 bolts)?

Once you pop the clips, you have to lift that edge up a little, then push it down towards the engine to release the lip at the other end of the box. You shouldn't have to remove anything. Make sure all the vacuum lines are attached to the intake tube after you put it back together. I pulled one of them loose the other day when I was checking my filter, and the car wouldn't run after that. I found it right away, but it would've been easier to just doublecheck it after I put the filter box back together.

The Amsoil air filter part number is TS-74, in case you're interested. I don't know the K&N number offhand. Sorry.

Hey Felix,

Yeah the airbox is a pain to open up. Just Rich says, edge up the left side (facing toward rear of car/engine bay) the push to the right to unengage the clips on the cover. Just be careful not to pull the cover too high and slip off some vacuum lines like I made the mistake too The car wouldn't start properly and kept stalling! scared me!

Anyways the K&N part# is: 33-2075

I got mine from Cobb Tuning for $40 plus like $6shipping. Pretty decent price.
