Do not choke your high-performance engine with a restrictive factory paper element. The Green Filter Replacement Element, registered under manufacturer references P457612 and 7711158636, is custom-engineered to drop straight into your original factory airbox housing. Utilizing a multi-layer oiled cotton weave, it dramatically drops restriction levels while enforcing surgical microscopic filtration.

An essential upgrade for routine maintenance intervals or to support the mechanical customization of your performance vehicle, this permanent washable unit optimizes throttle reaction and eliminates repetitive replacement costs.

The silent penalty of OEM paper air filters: what your sports engine loses on every acceleration

To develop its engineered horsepower, a high-output internal combustion engine demands a massive volume of cool air with the absolute minimum of physical restriction. Running a standard cardboard or paper air filter means you are unknowingly suffocating your powertrain. Factory filters quickly saturate, their fibers clogging within a few thousand miles, creating a heavy airflow bottleneck inside your factory intake channel. Operating without this premium replacement Green filter under reference P457612 or 7711158636 forces your turbocharger or multi-valve induction setup to work harder simply to draw enough oxygen for combustion. Consequently, you lose vital throttle response (turbo lag), your torque curve sags prematurely at higher RPM, and your engine management ECU increases fuel injection parameters to compensate for intake inefficiencies. Furthermore, discarding a cheap filter at every fluid change is a continuous waste of money. Omitting this high-flow filter deprives your performance car of a clean induction note and optimal induction acoustics.

An engine operating with heavily restricted intake paths experiences elevated internal operating temperatures and accelerated wear on turbocharger compressor wheels. Choosing a generic, uncalibrated cotton filter introduces structural bypass leaks, exposing your mass airflow sensor to harmful dust particles.

Deep-pleated woven cotton technology made in France for maximized structural airflow

Green Filter develops its filtration components to uncompromising industrial motorsport standards. Unlike restrictive disposable filters, this panel utilizes dual layers of natural woven cotton, suspended securely within an epoxy-coated galvanized steel mesh structure. This specialized architecture expands the active surface area while capturing microscopic dirt particles through an engineered technical oil compound. Part number P457612 delivers a precise edge-molding profile that seals flawlessly inside the OEM housing lip, preventing unfiltered air bypass. It stands as an absolute asset for your regular vehicle maintenance or to refine the technical customization of your sports chassis.

Dedicated vehicle application and strict engine compatibility layout

This specific filter element, aligning with factory part number 7711158636, is custom-tailored to provide an absolute drop-in fit for the original airbox configurations of the following models:

Frequently Asked Questions (FAQ)

How do I clean and recharge my permanent cotton Green replacement filter?
The primary benefit of this panel is its lifetime reusable design. When the cotton fibers turn gray (typically every 10,000 to 15,000 km), remove it from the airbox, apply the dedicated Green Filter cleaning solution, rinse with lukewarm water, let it air-dry naturally, and mist a light, even coat of Green Filter servicing oil before dropping it back into place.

Does fitting part number P457612 require an ECU software remap or engine tuning?
No calibration is required. This panel filter drop-in conforms to the physical dimensions defined by the factory engineers. It delivers an optimized, highly stable flow pattern that your factory ECU automatically balances using mass airflow or manifold absolute pressure telemetry. It operates perfectly on both stock vehicles and Stage 1 or Stage 2 builds.

Unshackle your induction system and let your engine breathe to its full potential

The mechanical output and long-term health of your premium powertrain rely entirely on the volume and purity of the air it breathes.
