BMW 4 Series (G22/G23) engine tuning & performance parts
R44 Performance stocks 37 engine performance parts for the 2020–2027 BMW 4 Series (G22/G23). Parts include intakes & air filters, turbo upgrades, heat management and fuel system upgrades, from brands including Genuine BMW, MOTUL, LEIB Engineering, Funk Motorsport, Pure Turbos, VP Racing.
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 4 Series (G22/G23), fit it at R44 HQ in Wembley, and deliver across the UK and worldwide.
