Includes a full set of polyacrylic intake and viton exhaust valve stem seals! Looking to replace your valve stem seals due to leaks, cracks, splits, or even during an upgrade of your camshafts, valve springs, or valves? Supertech valve stem seals are the way to go! This cheap but effective seal replaces the stock BMW seals that are notoriously prone to issues due to heat cycles and chemicals which cause the seals to become weak and brittle. Supertech seals offer a significantly longer life span and are resistant to both heat and chemicals thanks to their use of Viton or Polyacrylic construction (dependant on valve type). That means less time in the garage and more time on the street or track! These seals are also great for anyone who is looking to upgrade to dual valve springs thanks to the seal's overall thinner outer diameter! Guide OD: 8.8mm/.347" Seal OD: 12.2mm/.480"

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.

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.

Looking to replace your valve stem seals due to leaks, cracks, splits, or even during an upgrade of your camshafts, valve springs, or valves? Supertech valve stem seals are the way to go! This cheap but effective seal replaces the stock BMW seals that are notoriously prone to issues due to heat cycles and chemicals which cause the seals to become weak and brittle. Supertech seals offer a significantly longer life span and are resistant to both heat and chemicals thanks to their use of Viton or Polyacrylic construction (dependant on valve type). That means less time in the garage and more time on the street or track! These seals are also great for anyone who is looking to upgrade to dual valve springs thanks to the seal's overall thinner outer diameter! Guide OD: 8.8mm/.347" Seal OD: 12.2mm/.480"
