Honda J37 3.7L V6 Stainless Header Flange

Precision laser cut from 3/8" thick 304 Stainless Steel, our header flanges are manufactured in the U.S. and are machine surfaced. These header flanges are specifically made for the Honda J37 3.7L V6 Engines found in 2007-2014 Honda/Acura vehicles.

Port Size: 2 1/2"

Preformed flange stubs are 2"-3" long, and have one end perfectly formed to the port shape of the flange using the appropriate tubing size for that port. This can drastically decrease overall build time.

We carry over 450 different header flange designs, so if you don't see the flange you're looking for, talk with one our tech reps about custom header flange cutting.
