Like CK6speed said.... very easy to remove. I did mines over the weekend.

 

thanks alot

 

Has anyone tried the K & N filter yet on the RX 330? If so, any notice of improvement? I would like to make mine a little more "exicting". Two bolts removes the small rear muffler with chrome tip. I am thinking of trying a straight pipe there with a new tip. The main muffler would still be intact. Maybe a little more sound and along with the K& N filter maybe a small gain in performance. Any thoughts?

Aloha,

This thread contains some thoughts on K&N filters:

p.s. it is not cost cutting - new filters are much easier to recycle since they are all paper. Ecology is important these days.

 

My air filter cover seems not able to cover at the left side, there is a gap of 1/2 inch gap, any suggestion ?

 

Tried the K&N in my wifes RX-330. Notice a little power increase and MPG increase. While you in there you should remove the charcoal filter located in the top portion of the air box lid. It will help complement the K&N filters air flow to the engine. They started putting them in the air boxes in 2006 for some emissions crap. It just neutralizes any fuel fumes which come back from the intake throught the intake tube so they don't get relaesed into the engine bay and atmosphere. Just drill out the hot melts and it will come out easy. I have also thought about removing the secondary muffler and running a straight pipe or putting on a TRD sport muffler. Have not done either yet. Hope this helps, not many choices for souping up your RX!

 

Make sure you have the filter in the right way. If you look at it the one corner has a longer lip on it. Is should go in the front right corner of the air box. This may be causing you lid problem.

 

finally fixed it the cover should slid from the left side and under the tab of the host.
