A lot of aftermarket intakes use K&N filters. Stillen doesn't seem to be much different.

 

I kinda just want the pipe and heat shield... not the filter. But I doubt I'll be able to do that.

 

Cone filters are interchangeable. You just have to make sure you get the right diameter and length.

 

I used NGK Iridiums. I forget the part # but I got it online here I think from a DIY thread. Same temperature range as stock.

KNN filters work fine, just get the kit and be done with it.

 

K&N filters flow too good. I'd rather have more protection than HP's

 

Best I've ever heard my car sound overall is with the stillen kit with the z-tube. If memory serves the 5/16ths spacer sounded awesome in that collection also. Stock everything else.

Performance? I don't know but it sounded ferocious. My mileage plummeted because I was flooring it everywhere I went.

 

I have the MREV2, 5/16 spacer, NISMO R tune CAI and a K&N filter for it. My plugs are WAY over due but we get about 21 mpg average.

 

What is a NISMO R Tune? Also that really awesome mpg's

 

What are the best plugs for these cars and at what mileage should they be changed

 

NGK Laser Platinum PLFR5A-11... basically OEM unless you have some high performance goals or are running FI in which case maybe we're having a different conversation.

 

So for daily driving I should order those plugs you just listed?

 

I think that would be a wise investment.

 

Great, sounds good. I'll order some when I get the new Stillen Intake

I think that plenum spacer is SUPER over priced.... Goodness..

 

keep your eyes in the marketplace for great deals... especially down there!

 

So let me get this straight, you're going to spend $250 for an intake that nets you zero gains in HP yet you think a spacer for the same price that will add a good 10-15 HP is overpriced?

Oh grasshopper you have lots to learn about the G.
