Upgraded valves designed for high horsepower applications! Our valves are not finished from generic blanks rather they are specifically designed for each and every application. We work relentlessly, testing and researching every aspect trying to improve the air flow of our designs. With every valve design, we strive to maximize durability through higher fatigue resistance and tensile strength. Each valve tip is hardened beyond 52HRc. It’s unlikely you will find any of our competitor’s valves with stricter dimensional tolerances than our Supertech valves. Combine that with finished seats with equally strict run out tolerances and you won’t find a better sealing, better performing and easier to install solution anywhere! Optimum high flow rates are achieved by ensuring that our valves are manufactured with the best angles for each application. We consider back cut, under cut and valve head angles for each application to produce the optimum high flow rates for each application. In 2006 we introduced our stem Superfinishing as a standard addition to all of our valves at no additional cost. When our Superfinish is combined with our Black Nitrided valve, it reduces the surface roughness to 1/3 of our chrome coated valve. The end result… unsurpassed performance and durability. Our exhaust valves are made from EV16 (21-8N) or EV8-Nb/w for greater strength at higher temperatures. Black Nitride Coating: This is a hardening treatment that has been steadily growing in popularity over the last several years. These black Nitride coated valves feature harder surfaces and smoother finishes, providing less friction and subsequently longer life. Please see below for more benefits of our Black Nitride valves. Black Nitride Coating Head Diam: 30.50mm Material: Black Nitride Groove Type: Triple Groove Length: 105.65mm Stem Diam: 5.95mm Size: Std

The exhaust valves in your vehicle allow the exhaust port to be sealed during the combustion process, so that the engine can run at top efficiency. If the timing belt or lifter breaks, this can cause the piston to come in contact with the valve and bend or break it, causing an improper seal. This will cause a rough idle, misfires, and a check engine light condition. Be sure to replace your bent or broken valve today and keep your engine running strong.

Generally, an intake valve is the name for a valve that allows air or fluid to pass through it, typically during the intake phase of an engine's operation. In your car, the intake valves allow an air and fuel mixture into the engine's cylinders where it can then be compressed. The valves shut during the compression phase and the spark plug ignites the air and fuel mixture, creating a force that propels the car forward. If these valves aren’t working properly, the engine will create less power and it can damage the engine over time.

As the M52tu,M54,M56 engines start to rack up the miles it is a good idea to replace the oil pump with this Genuine BMW part. We also recommend replacing the oil pump nut as it has a tendency to back off over time especially during track use. While you are in there we also recommend replacing the oil pump nut with this drilled oil pump nut as the stock nut has a tendency to back off the shaft especially on track driven cars.

Upgraded valves designed for high horsepower applications! Our valves are not finished from generic blanks rather they are specifically designed for each and every application. We work relentlessly, testing and researching every aspect trying to improve the air flow of our designs. With every valve design, we strive to maximize durability through higher fatigue resistance and tensile strength. Each valve tip is hardened beyond 52HRc. It’s unlikely you will find any of our competitor’s valves with stricter dimensional tolerances than our Supertech valves. Combine that with finished seats with equally strict run out tolerances and you won’t find a better sealing, better performing and easier to install solution anywhere! Optimum high flow rates are achieved by ensuring that our valves are manufactured with the best angles for each application. We consider back cut, under cut and valve head angles for each application to produce the optimum high flow rates for each application. In 2006 we introduced our stem Superfinishing as a standard addition to all of our valves at no additional cost. When our Superfinish is combined with our Black Nitrided valve, it reduces the surface roughness to 1/3 of our chrome coated valve. The end result… unsurpassed performance and durability. Our exhaust valves are made from EV16 (21-8N) or EV8-Nb/w for greater strength at higher temperatures. Black Nitride Coating: This is a hardening treatment that has been steadily growing in popularity over the last several years. These black Nitride coated valves feature harder surfaces and smoother finishes, providing less friction and subsequently longer life. Please see below for more benefits of our Black Nitride valves. Head Diam: 31.50mm Material: Black Nitride Groove Type: Single Groove Length: 105.65mm Stem Diam: 5.95mm Size: 1mm+
