What is extrude honing?
Extrude Hone is a subdivision of PowerFlow Corp. It is actually slang now for the process that they perform on intakes, impellars (jet skis), heads, and exhaust manifolds. The process involves taking a metallic putty (like abrasive toothpaste) which is presssurized inside of the part to be “honed”. The putty is moved/flowed back and forth by hydraulic pistons that are connected to the ports of the fixture/jig that is attached to your part. This abrasive scrubbing machines off a part of the finish, leaving it almost perfectly smooth. The process is also used to balance the flow in intakes, head ports, and exhaust ports since it is extremely accurate.
