Accurate fit and high-quality sealing materials combine with specially impregnated filter media. Robust pleat geometry and OE-level testing ensure reliable performance under heat and pressure.


Cleaner engine intake air, with specially impregnated filter media

Filter media is specially impregnated to provide moisture resistance and greater tensile strength, helping the filter maintain integrity in humid conditions. Embossing on the media forms robust pleats that increase surface area without collapsing under stress.

Improved protection against dust and moisture reduces the risk of contaminants reaching the engine. That helps preserve engine components and supports vehicle longevity when fitted correctly.

Factory-style fit and seal, with high-quality sealing materials

Sealing materials match Original Equipment standards to ensure accurate fit and reliable sealing at the intake interface. All functional and quality tests are performed according to the same standards applied to OE parts.

Straightforward, reliable replacement that aligns with factory mounting points and minimises the chance of air bypass. Workshops benefit from reduced refit time and fewer fitment issues.

Durable performance under harsh conditions, with heat and pressure resistance

Construction is designed to withstand heat and pressure, while robust pleat geometry maintains shape during demanding operating conditions. Tests mirror OE criteria to confirm endurance and longevity.

Supports the long service life required by vehicle manufacturers, reducing frequency of premature replacements. Suitable for vehicles exposed to high temperatures or heavy use when installed by trained personnel.
