Darton Sleeves 200-023 Seal Tight BMW M3 E46 S54B32 86 mm

Flanged Darton Dry Sleeves replace your factory cylinder liners with high strength iron sleeves, eliminating a weak link in your engine and providing you with the strength needed to get the full potential from your setup without losing any sleep worrying about cracking a factory sleeve and taking the engine out.

This particular model of sleeve is designed as one step up from a stock replacement sleeve, not a high power race engine. This would be perfect if you are just looking to get a proper cylinder wall finish without compromising the structural integrity of your block by removing material.
