These Motorsport valve springs are from the Sport Evo 3 model but can be used in all E30 M3s (and others). We found that the stock original valve springs can be too weak when used with upgraded cams and this genuine BMW Motorsport part is an upgrade over the original design. Valve springs also get weaker over time so these are the perfect replacement when refreshing the S14 cylinder head. A weak spring can lead to a burnt valve seat or even a bent valve. These are also the stock springs in the M88/S38 and Euro S50B30.

Priced per valve (price includes 1 inner and 1 outer).

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

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.
