o2 housing
I can't say for sure... but I've heard that the ported housings don't perform quite as well as aftermarket ones. I've seen a couple dyno sheets, but I can't be sure that it's actually the housing making the difference. That being said, I know that ported stock housings don't have the reliability problems that some aftermarket ones do. Sorry I can't be more help...
I've done a lot of research on the best o2 housing, and I've come to the conclusion that the WORKS 76mm version is hands down the best when accompanied with they're downpipe. It's thermal coated to keep the heat in instead of radiating throughout your engine bay and your ACD (with the downpipe). Perfect setup, and costly.
Also this system needs no modification to fit...
