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).

BMW cylinder head bolts are almost always stretch bolts and should never be reused after removal. Reusing old bolts can lead to a weak seal between the cylinder head and engine block, allowing the head to lift and cause potentially catastrophic damage. Replace your old cylinder head bolts with these brand new Elring bolts to ensure your head is properly secured to prevent damage and keep your engine healthy. Replaces BMW # 11128513128
