Turner Motorsport has everything you need to upgrade your BMW through our stages of performance or to keep your car in peak condition with our range of the latest in proven OEM cooling parts.

Built on decades of BMW racing heritage, the Turner Motorsport OBD1 Coilpack Heat Shield delivers uncompromised thermal management for M50 and S50 engines. Factory plastic engine covers degrade and fail under track conditions and extreme bay temperatures, especially in turbocharged setups where hot top-mount downpipes pass directly overhead. Engineered in-house as a rugged, direct replacement, this full-coverage shield insulates your ignition harness and coilpacks against radiant heat damage while giving your engine bay a track-proven look.
