Eventuri BMW 330I/430I (G20/G21/G22/G23/G26) Carbon Fibre Intake System

Give your B48 turbo a genuinely less restrictive path to breathe with the Eventuri Carbon Fibre Intake System, purpose-built for the G20/G22-generation 330i and 430i. Because the intake sits right next to the exhaust manifold on this platform, heat soak is the biggest threat to performance - Eventuri's answer is a fully sealed carbon airbox with a gold-reflective heat shield to block radiative heat transfer, keeping intake air temperatures stable even under sustained load.

A sealed design usually means a single restrictive air feed, so Eventuri added a second cold air inlet drawing from the gap between the wheel arch and chassis - visible behind the front wheel after installation - giving the turbo a larger area to pull from. The factory's convoluted, flexible inlet tube is replaced with a smooth 111mm (4.4") carbon tube that tapers cleanly to the turbo inlet, paired with a custom ISO-tested high-flow dry filter offering more filtration area than stock.

Works with: Stock ECU - available in V1 (pre-November 2018, MAF sensor) and V2 (post-November 2018, temperature sensor) variants to match your car's specific setup.

Why Choose This Intake System

• Fully sealed carbon airbox - prevents heat soak from the nearby exhaust manifold
• Dual cold air feed design - second inlet from the wheel arch gap reduces flow restriction
• Gold-reflective heat shield - minimises radiative heat transfer for stable IATs
• 111mm (4.4") smooth carbon inlet tube - replaces the factory's convoluted, turbulence-prone tube
• Custom ISO-tested dry filter - larger filtration area than the stock filter
• Available in V1/V2 variants - matched to your car's build date and sensor type
