Eventuri BMW G42 M240I Carbon Fibre Intake System

Overcome the M240i's biggest intake weakness with the Eventuri Carbon Fibre Intake System, purpose-built for the G42 B58. Sitting right next to the exhaust manifold, the factory intake is highly prone to heat soak - Eventuri's fully sealed carbon airbox, backed by a gold-reflective heat shield, tackles that head-on by encapsulating the filter and blocking radiative heat transfer, keeping intake air temperatures low even under sustained load.

A sealed design usually means a single restrictive air feed, so Eventuri identified an unused opening into the wheel arch area and used it to add a second cold air feed - extending a scoop visible behind the front wheel after installation - giving the turbo a larger area to draw from. Built around the same patented Venturi housings and Gen 2 bespoke filters used across Eventuri's B58 range, the system maintains laminar airflow for reduced turbo drag. The result: a dyno-proven 17-20hp and 11-20ft-lb gain over 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
• Patented Venturi housings with Gen 2 filters - laminar airflow, reduced turbo drag
• Dyno-proven gains - 17-20hp and 11-20ft-lb over stock
• Available in V1/V2 variants - matched to your car's build date and sensor type
