Supertech uses over 20 years of manufacturing experience to design and produce their Valves. Intensive testing and working closely with engine builders provides continuous improvements and provides the market with the best possible product for every application. High flow rate, durability and quality are all of great concern.

Supertech Extreme Flow Performance Valves for Pro Street and Racing are engineered for High RPM and High HP. Extreme Flow Valves outperform any other valve on the market today, and with their Nitride Coating are perfect for High Temperatures (and run cooler which improves value life), Nitrous, Turbos and Superchargers. For naturally aspirated motors these valves will give you a much greater cylinder flow for good HP gains.

These exhaust valves are one piece forged, high temperature, high nickel, stainless steel alloy. Valves are CNC finished to strict tolerances making these valves the choice for the most demanding race classes. These Nickel based alloy materials are used for exhaust valves in engines that reach very high temperatures and its use is growing with the application of turbos and superchargers. All valves are swirl polished, have stem undercut and a hardened tip.

Great price, but don't stack multiple wires
Size: 300A
I used this as a junction point on a 1 gauge wire. I added an 8 gauge wire to one side, and the cover would not seat. I had to bend and maneuver the ring terminals to make the cover catch. For the price of the items, if used without any secondary wires attached and interior use only, this is an unbeatable deal.
