Evolution Racewerks

Cooling is the first thing to run out on a boosted BMW, and Evolution Racewerks builds the charge coolers and intercoolers that buy back the headroom. The bar-and-plate cores carry more thermal mass than the factory units, which is what keeps intake temps from climbing into timing-pull territory on a back-to-back pull. Their charge pipes also delete the factory plastic coupler that is a known weak point under boost. When a Stage 1 or Stage 2 car is heat-soaking on the second hard pull, a competition cooler from Evolution Racewerks is usually the fix that holds the tune's numbers session after session.
