Don't worry - I had the same question before I did it. Disconnect the air intake hoses and then pull up (quite hard) on the air filter housing. You'll need a torx T20 to open it up if I remember correctly. Reassembly is reverse of disassembly.

No big deal...
Open the hood...
Pull the air filter housing out....
Unscrew the filters loose....
Replace with new K&N filters...
Just reverse the mentioned steps .....
Be sure everything is tight....
Enjoy!

See Garage
Pull up the entire airbox as a unit. No need to remove the front part nearest you. (I broke some pins trying to do that while learning).

On reassembly, make sure the airbox exit tube nests correctly into the round plenum intake (at the back). I didn't mess this up, but others have... LOL!

This is very important. THe tube in the back moves around so I use a long screwdriver to hold it in place while I push it back on. Good luck!

I have BMC filters on my C32, the car seems to run smoother at higher speeds. I will test ITG and K&N in the future....

Verb04, what do you think of your K&N so far?

The K&N's are OK. I feel it a little more free flowing. I wonder which brand is the best.
Thanks
