BMW Z4 Performance Air Intake - Dinan - Semi-Open - Carbon Fiber (G29, 2020-2026). Purpose-built to increase airflow and sharpen response while bringing out the Z4 M40i's turbo character.
Dinan reworked the entire lower airbox, expanding volume by 60% and housing a custom filter with 40% more area (115 in² vs 82 in²). A patterned secondary inlet on the cold side supplements the factory duct without raising turbo inlet temps in testing. The semi-open layout and resonator delete add induction presence, while flow improves by 58% or more with gains up to +13 whp and +14 lb-ft on a stock car. 2x2 gloss twill carbon fiber and a brace-ready lid round out a straightforward install and future-ready airflow for higher-power builds.
