used one of those mushroom style air filters?

If so...
1. How has it held up?
2. How much did you buy it for?
3. Anyone test one vs a big K&N filter(talking large filters like 6" + long/etc)


Thanks in advance!

I run twin turbos and twin baby K&N filters. The filter is roughly 5.5" at the base...4.0" at the top and 5.25" long..small cone filter....ran 155mph with them on the turbos...took them off and ran 155mph...I'd stick with K&N.

Thanks for the reply. The place where my turbo sits, I can't run a normal conical filter without a 90* bend and the rubber bend on there I think is closing on itself because I see 14# and then it tails off to 10# of boost. So I have 2 main choices, make the bend aluminum or use a mushroom like filter.

Incase anyone asks, the engine is a stock ls1 heads with 9.5 cr(forged internals) with a 208/230 .549/.579 and 121lsa cam. Springs are brand new comp 918s with stock lifters/push rods. Turbo is a 70mm with a p-trim exhaust wheel.
