HF-Series 4" intake upgrade kit Mercedes A45 W176, CLA45 117, GLA45 AMG X156 MERCEDES-BENZ (HGAIUA45)

This 4" intake upgrade kit is the perfect optimisation of the air filter system of your A45 AMG, CLA45 AMG and GLA45 AMG; it is designed for maximum performance and also treats you to an incomparable intake sound. Also tested on tuned engines and highly recommended. As you can see in the product images, the original air filter assembly is reduced to 65mm inner diameter by the plastic adapter plate, which means that even with standard software there is a drop in power in the upper rev range. With our intake upgrade we increase this to an inner diameter of 98mm (102mm/4" outer diameter) and, in combination with the Pipercross air filter, increase the air flow by 52.43%. But we achieve higher max. power not only in the upper rev range: there is more power across the entire rev band. This also leads to enormously improved response at all engine speeds, as the power diagram further below impressively shows.

Technical details:

• More power and more torque across the entire rev band thanks to better, faster and greater air flow compared with the standard air filter system Increased air volume thanks to optimum intake performance -> faster and more effective cylinder filling Sportier and more aggressive intake sound Greatly improved response The air is thus passed on to the engine as cool as possible Product workmanship of the highest standard incl. certificate (so no registration required) Scope of delivery: filter spigot, black powder-coated, incl. HF-Series air filter (oiled) by Pipercross and all required fitting parts + certificate Oxygen is needed for fuel combustion. The more oxygen gets into the engine, the more fuel can be injected, which in turn leads to a significant increase in power.
