Air Filter Housing Restriction

True, I doubt it would be a big deal either way. Let us know if you feel or hear any difference.

I certainly don't have those problems since I yanked out my stock air box and replaced it with an EVO Hi-Flow three years ago. Forget the fairytales of CEL and MAF problems; if you know how to properly oil a cone filter, those problems don't arise. You'll never get the sound an EVO produces with a modified stock box.

Jmatta,

I'm with ya on the properly serviced, cottom based, oil filter thing. Some people just soak the media to the point of it dripping. Just follow the directions!

I'd love to put an EVO on my car. But cost and the love of tinkering prohibit it at this time. I'll let the forum know after I swap out for the screenless stack.

I hear you...good luck on the swap. I truly believe Porsche purposely put all this stuff in our cars (baffles, screens, secondary cats) to keep them quiet for the EU restrictions. Our cars should have a nice sound, just as Dr. Porsche intended them to in the beginning.
