Why this upgrade is a no-brainer

• Oil-free, triple-layer synthetic media for strong filtration and easy upkeep
• Cleanable and reusable to save money over disposable paper inserts
• Deep, wide-radius pleats maximise surface area for superior flow and dust loading
• Soft bump seal moulds to the OE air box for a secure, leak-free fit
• Robust polyurethane frame resists heat and keeps its shape over time
• Direct-fit insert that installs quickly with basic tools

Construction and tech

Dry synthetic matrix: The Pro DRY S three-layer media delivers impressive filtration efficiency and long service intervals with zero oil required. Ideal for daily use and spirited road driving.

Optimised pleat design: Deep, evenly spaced pleats create a larger effective surface area than a standard paper element, helping maintain airflow and performance between cleans.

Precision sealing: The compliant bump seal conforms to minor variations in the air box for a dependable seal without extra gaskets or sealant.

Durable housing: A full polyurethane surround handles repeated heat cycles and under‑bonnet conditions while maintaining a consistent fit.
