Anybody know where I can find a 4inch maf adapter? I need it for a HKS filter. Which are supposedly 4inch. Not even ebay has them. The only one that I see coming up a lot is the vibrant 4.5inch adapter. An original HKS replacement adapter is $65 shipped. So much for a friggin' adapter!

 

Make one out of a 4 inch pipe and a flat piece of metal?

 

Yea thats what I did for my current AEM dryflow. Had my friend weld up a NICE piece. It was great and all apart from the fact that it doesn't seal against the maf properly . So much effort, so much fail. I'd rather just buy one this time.

 

No one can help?

 

Autozone and Pepboys has one , thats where i picked mine up for about $12 .
