CNC machined US milled 6061-T6 billet aluminum P75 (B18A/ B18B/ B20A/ B20Z) non-VTEC cylinder head flange with a -16 ORB thread.
You can select a -16 ORB to 1.25" hose, -16 ORB to -16 male flare, or you can grind the tips of the flanges threads, insert a 1.25" tube and use the generous o-ring seat as weldable socket for custom jobs. The backside of the flange has an o-ring grove for a positive seal against the cylinder head without the hassle of Hondabond.
The flange includes two stainless M6 socket head bolts and an o-ring.
