What are the best first engine upgrades for the Z4 (G29)?

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.

Do I need a tune after fitting performance parts?

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.

Will performance upgrades affect my warranty or insurance?

Modifications can affect manufacturer warranty cover and must be declared to your insurer. If your Z4 (G29) is still under warranty, check with the manufacturer or dealer first, and speak to your insurer before fitting.
