BMW M235i (F22/F23) engine tuning & performance parts
R44 Performance stocks 104 engine performance parts for the 2014–2016 BMW M235i (F22/F23). Parts include intakes & air filters, ECU tuning & flash tools, charge pipes & turbo inlets and intercoolers & charge coolers, from brands including MMX, Genuine BMW, EVENTURI, R44 Kits, Ramair, CSF.
Most builds follow the same order: an ECU tune first, then intake and cooling upgrades such as intakes, charge pipes and intercoolers to keep temperatures in check, then fuelling, turbo and internal upgrades for bigger power targets. Each step supports the next, so it pays to plan your build as a whole.
Results depend on the combination of parts and the tune that supports them, so speak to our team before you buy. We can recommend a proven setup for your M235i (F22/F23), fit it at R44 HQ in Wembley, and deliver across the UK and worldwide.
