I have a K&N air filter on my gt30.

Looking for something that flows better than this.

The gt30 is sucking so much air it is concaving the filter..


See pics here:

 

Just curious, how how does it get under your hood? one of my buddies had that happen to his in his 240SX with SR20 and it was more because of the heat that was generated that made it brittle and weak. Once the underhood temps were corrected, no more problems. Also with K&N

 

I'm using one from ATPturbo and it's been doing great for me.

 

my k&n is holding up great, but my gt30 is only seeing 17psi. try using a shorter filter, seems like it would be more structerly sound.

 

My k&n is doing fine on 15psi

I would think the OP could build a cold air box for that filter to keep heat away, maybe a custom hood scoop too

 

Are you sure the engine isnt moving at higher rpms and causing it to rub against the hood?

i heard geoff saying that k&n were giving him problems b/c overtime they wouldn't last as long. and he recommended green filters, i know a few people on clubrsx.com had been using them w/ no problems. i also got one too here are some pics of mine.

 

No heat near it at all.
This happened on the dyno with the hood open.

Im sure the filter is getting enough fresh air.

This is my hood

anyone try the new x-stream filters?

 

I've never seen a K&N do that as a result of it being sucked in like that, was the filter new when you put it on? I've seen filters get bent on something, once the metal screen around the filtration material gets bent then it will loose it's shape easier.

 

^^nice call. like a soda can, once its been damaged on its side thats going to be its weak point therefore making it easier to crush.
have you tried a filter the shape of a perfect sphere? that should be the most structerly sound IMO.

This filter is a 4" K&N? You don't happen to have the part number for this filter, do you?
I've been having a hell of a time finding a filter short enough to fit.
Thanks

 

I think it's this one, I have the same thing.

I'd take that filter off immediately before it continues to suck the filter in until the filter gives way; and say goodbye to your turbo. I've seen it happen.

 

Would that 4" K&N restrict air flow at all?

 

Thanks man, thats exactly what I need.
Cheers

 

this may be why japanese tuners like to use mushroom style filters as they have an inner ribcage that holds and supports the foam from the inside
