Performance Air Filter for Mini Cooper S R53, Suzuki Swift / SX4, Fiat Sedici

Improved Airflow for Mini R53 Tritec and Suzuki M-Series Engines

Who It’s For: Designed specifically for owners of the Mini Cooper S (R53) and the Suzuki Swift Sport running the Tritec and M-Series engine families. This is for the driver who wants better throttle response without deleting the factory airbox.

The Problem: The Tritec W11 supercharged engine and the high-revving M-Series M16A are both sensitive to intake restriction. Factory paper filters are designed for cost-efficiency and filtration of large debris, but they create a bottleneck. These OEM filters typically only filter down to 10 microns and use thick paper pleats that can become a literal wall for air as they get dirty, causing the supercharger in the Mini to work harder and the Suzuki to lose its top-end pep.

The Solution: This high-performance panel filter replaces the restrictive stock element with multi-layered cotton gauze soaked in low-viscosity oil. We engineered this part to correct the factory design flaws of the M-Series and Tritec intake paths, delivering reliable performance by capturing impurities as small as 7 microns while significantly increasing the volume of air reaching the intake manifold.

The "Full Moulding" construction ensures there are no welded joints that could fail under the high-vacuum conditions of a forced-induction or high-RPM engine.

Why This is the Ultimate Upgrade

• Enhanced Filtration: Captures particles down to 7 microns, providing superior protection compared to the 10-micron OEM standard.
• Full Moulding Construction: Produced from a single mould with no welded joints, preventing the structural failure or breakage common in cheaper aftermarket filters.
• Lifetime Durability: Constructed with epoxy-coated alloy mesh to resist petrol fumes and oxidation, ensuring the filter lasts the life of the vehicle with proper cleaning.
