Eventuri Carbon Fibre Cold Air Intake System for BMW X3 M40i G01 and BMW X4 M40i G02 B58D - Sealed Airbox High Flow Induction Kit

Maximise reliable performance and airflow on your BMW X3 M40i or BMW X4 M40i with the Eventuri Carbon Fibre Intake System for the B58D engine. This premium carbon fibre cold air intake is engineered for the G01 X3 M40i and G02 X4 M40i to reduce restriction, keep intake air temperatures low and deliver consistent, repeatable results. If you are searching for BMW X3 M40i intake, BMW X4 M40i intake, B58D cold air intake, carbon fibre induction kit, Eventuri intake for G01 G02 or a sealed airbox performance intake, this is the upgrade you want.

Designed around a fully sealed carbon fibre airbox, the Eventuri system combats heat soak in the M40i engine bay where the intake sits close to the exhaust manifold. The sealed design pairs with a gold reflective heat shield to help maintain low IATs, giving stable performance for daily driving and spirited road use. A large pre-preg carbon fibre intake tube with a 109 mm internal diameter smoothly tapers to the turbo inlet for an uninterrupted, high volume airflow path. This is matched to a bespoke high flow dry cone filter with ISO-certified filtration and a larger surface area than the factory element, optimising both flow and filtration.

At Nforcd we have installed and used this Eventuri intake on customer BMW X3 M40i and BMW X4 M40i B58D builds, and feedback has been excellent. Owners love the premium carbon finish, the precision fitment and the confident, repeatable performance that the sealed cold air design provides. If you are upgrading your G01 or G02 B58D, this is the carbon fibre intake system we recommend.
