Are they selling any stillen filters yet? I want to get the stillen intake but yet to see any filter for sale.

?
The intake kit would come with filters.

I want to get a spare one.

the kit comes with K&N filters... you can always buy a similar one.

Quick question I am new to these kind of stuff. How often do you have to change and clean the filters?

depends on climate. If you live in a dusty, dirty place or drive down alot of dirt roads, you'd have to clean them more often. I did mine after every 2nd or 3rd oil change, anywhere between 10-15k miles.

Thanks. That doesnt sound to bad. Also how do you clean it the right way?

if you decide to put on Stillen Dual High Flo Intake system they come with K&N filters which do not need to be cleaned as regularly as the stock filters. You can buy the K&N air filter cleaning kit when you do go to clean it..i would say every 20k miles to clean them or maybe even more

Waiting for a K+N drop in. The Stillen price for a non cai is steep at 400. I assume the filter is 80% of any hp increase on that system, even though I know I won't get that cool sound.

I have heard someones g35 sports with just a stillen intake, it screams when you step on it and it just gives you a sexy purr when not.

i've got the stillen exhaust and the dual stillen intakes. i absolutely LOVE the way this car sounds now...

would JUST an intake (no aftermarket exhaust..yet) give any sound improvements? I expect the performance wont be altered but I'd pay $300 for an increase in volume.. until I can free up the 1k for the exhaust too.
