I've searched around here and emailed Stillen and can't seem to find what the part number is for the K&N Filters . Anyone with the intake know the part number?

I dont think Stillen uses K & N filters? Because its a special cone shaped filter that also sucks air from the top edge of the cone.. why would you need one anyways, just wondering.

clean it....

[QUOTE=jdanielsg]I dont think Stillen uses K & N filters? Because its a special cone shaped filter that also sucks air from the top edge of the cone.. why would you need one anyways, just wondering. stillen uses the typhoon K&N filters for their setup

Stillen's Website says the use K&N filters. I know it is the "XStream" series. Cleaning isn't an option since I don't have the filters yet, I'm just wondering if anyone who has the intake might be able to tell me the Part # for the filter.

I've done a lot more searching and came down to these two filters

RX-4950
or
RX-4960

I'm just not sure of the intake piping diameter.

Can anyone help?

red45, did you get the part number what we need? I have the stillen intake gen 2.

U talkin abt gen1, 2 or 3 ????
Gen3 diameter is 3in

gassian, gen2

pipe diameter is 2.75 I think...

just call Stillen and ask them.

Hmm, well I've got the Stillen Gen 3 intake and I've recently ordered replacement filters, the ones I got from Stillen were the RX-4990

Dunno about the other numbers suggested above

Didnt even know Stillen used K&N filters. Then what the benefit of buying the more expensive (stillen) intake? the tubing design can't be much different since it has to be designed to fit within the space available. I may be wrong here buy the sound produced is from the filter design, not the tubing design. Hmm interesting!!

^ it all about the tubes design, length, quality and the heat shields pretty much. but in this case the Stillen Gen3 is totally different from what K&N offers for our cars so its more than just the filter that matters, though its one of the most vital parts.

yes they use kn regular cone filters.
ill check on the part number for you, but like others said just clean them.
i clean mine each year, takes a day to do it and its no prob.
