HF-Series A45/ CLA45/ GLA45 4" Intake Upgrade Kit

4" Intake Upgrade Kit for the Mercedes-Benz A45 AMG + CLA45 AMG + GLA45 AMG

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

Also tested for power-enhanced engines and highly recommended. 

As you can see on the article pictures, the original air filter construction is reduced to 65mm inner diameter by the plastic adapter plate, which results in a performance drop in the upper speed range even with standard software. With our intake upgrade we increase it to an inner diameter of 98mm (102mm/4" outer diameter) and in combination with the Pipercross air filter increase the air throughput by 52.43%.

But not only in the upper speed range we achieve a higher max. power, but over the entire speed range is more power. 

This also leads to an enormously improved response behaviour at all speeds.

The technical details:

More power and increased torque across the entire rotation range thanks to better, faster and higher airflow compared to the standard air filter system

Increased air volume due to optimum suction power -> faster and more effective cylinder filling

Sportier and more aggressive intake noise

Greatly improved responsiveness

Thus, the air is passed on to the engine with maximum cooling

Product processing at the highest level

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