M3 (E90/E92/E93) ENGINE & PERFORMANCE

R44 Performance lists 56 engine performance parts for the BMW E90/E92/E93 M3, including intakes & air filters, oil coolers & radiators, ECU tuning & flash tools and forged engine internals. Brands include Genuine BMW, EVENTURI, CSF, Evolve Automotive, MMX, MOTUL, and every part is listed for the E9X M3 – check each product page for body style and model-year fitment.

For most turbocharged cars, the best first upgrades are an ECU tune and an intake, followed by cooling upgrades such as a charge pipe and intercooler. Each supports the next, so decide on your goals first – our team can suggest a setup based on how you use your car.

Bolt-on parts like intakes can usually be fitted on their own, but bigger changes – such as downpipes, larger intercoolers, fuel system or turbo upgrades – normally need a matching ECU tune to run safely and make full use of the hardware. Check each product page or ask our team.

Modifications can affect manufacturer warranty cover and must be declared to your insurer. If your E9X M3 is still under warranty, check with the manufacturer or dealer first, and speak to your insurer before fitting.
