View Full Version : K&N Filter at last !!

04-13-07, 03:14 PM
I just ordered and received a K&N performance air filter for my 05 Cadillac STS 4.6L V-8.
Replaces the stock filter, easy to install.
The replacement K&N performance filter is K&N part # 33-2356. This K&N filter fits the 05 thru 07 v-8 and v6, STS and SRX.
I wanted a cold air intake but as we all know there is not one available for the 05-07 STS, so this is the next best thing. I have installed it and I can tell the difference in power and I like it.

Nice! Mine should be coming in very soon and I can't wait to put it in! :) How was the change in sound? I hear there is quite a difference in sound and a better punch to the gas!

Great info, thanks!!! I checked the K&N website and as mentioned by others only the 2007 STS is listed, but they give a cross reference number of GM 25735595, which is the part number listed in my owners manual (2006 4.6L STS)
