BMC high-performance replacement air filter full kit (FB742/08_356) for McLaren 3.8L & 4.0L twin-turbo models. Increased airflow, reusable cotton element, and OEM-quality fitment.

Full Product Description

Upgrade your McLaren’s intake system with the BMC FB742/08_356 Performance Air Filter Full Kit — engineered to deliver improved airflow, enhanced throttle response, and long-term reliability.

Manufactured in Italy using multi-layer oiled cotton gauze, BMC filters are designed to maximise air permeability while maintaining superior filtration efficiency. The result is improved engine breathing without compromising protection — particularly important for high-output twin-turbocharged McLaren powerplants.

Unlike disposable paper filters, BMC filters are washable and reusable, offering a long service life and consistent performance under demanding road and track conditions.

The FB742/08_356 full kit is a direct OEM replacement, requiring no modifications and retaining factory airbox integration.

Ideal for standard vehicles or those running upgraded exhaust and ECU calibrations where improved intake flow supports overall performance gains.

Why Upgrade to BMC?

High-performance turbocharged engines rely heavily on efficient airflow. The BMC cotton filter media reduces intake restriction while maintaining filtration efficiency — supporting improved turbo response and optimised power delivery.

For road or track use, this is a simple yet effective upgrade that complements exhaust systems, sports catalysts, and ECU calibrations.

BMC Air Filters use cotton gauze to offer excellent filtration (especially when dusty unlike foam or paper) and are easy to clean for a very long service life. You need only clean them around every 15,000 miles.
