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.
Extreme engine bay heat kills ignition system reliability on the track. Engineered specifically for OBD2 BMW M52 and S52 platforms, our Stainless Steel Coilpack Heat Shield delivers track-tested thermal protection where your engine needs it most. Designed to cover the entire length of the valve cover, this shield acts as a thermal barrier for cooked coil packs and valve covers. Upgrade the look of your stock engine bay, or make this a non-negotiable upgrade for forced-induction setups with top-mount turbo downpipes routed across the top of the engine.
Built from heavy-duty 18GA 304 stainless steel with a brushed finish, this unit is engineered to withstand track abuse while eliminating the fragile factory plastic cover for good. Designed with our classic race-bred precision, it maintains stock ignition harness clearance and stock M5X coilpack fitment without compromise.
