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: 9.8mm/.385" Seal OD: 13.2mm/.520"
