HF-Series 4" intake upgrade kit Mercedes A45 W176, CLA45 C117, GLA45 AMG X156

This offered 4" Intake Upgrade Kit is the perfect optimization of the air filter system of your A45 AMG, CLA45 AMG und GLA45 AMG, which is designed for maximum performance and also gives you an incomparable intake noise.

Also tested for performance enhanced engines and highly recommended.

Like you can see on the pictures, the original air filter construction is reduced to 65mm inner diameter by the plastic-adapter-plate.

Already with series software, this leads to a performance drop down in the upper RPM range. With our Intake Upgrade Kit, we increase the inner diameter to 98mm (102mm/4" outer diameter) and also improve the air flow at 52,43% in combination with the Pipercross air filter.

The higher maximum performance we achieve is not only in the upper RPM range, it is up to the whole RPM range.

This also leads to an enormously improved response behaviour in all RPM ranges, like you can see on the impressive performance chart below.

Technical Details:
- More power and torque increase due to a better, faster and higher air flow compared to the standard air filter system
- Increased air volume due to optimal intake capacity -> faster and more effective cylinder filling
- Sportier and more aggressive intake noise
- Improved response
- Thus, the air is passed maximum cooled to the engine
- Incl. approval (registration free)

Delivery:
Air filter inlet incl. HF-Series air filter (oiled) by Pipercross and all necessary mounting parts + approval (registration free)

Oxygen is needed for fuel combustion. The more oxygen gets into the engine, the more fuel can be injected, which leads to a significant increase in performance.
