HF-Series 4″ upgraded intake system Mercedes A45 W176, CLA45 117, GLA45 AMG X156

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 rewards you with an incomparable intake sound.

Also tested on engines with increased power and highly recommended. 

 

As you can see in the product images, the original air filter assembly is reduced to an inside diameter of 65 mm by the plastic adapter plate, which means that even with standard software there is a loss of power in the upper rev range.  

 

With our intake upgrade we increase this to an inside diameter of 98 mm (102 mm/4″ outside diameter) and, in combination with the Pipercross air filter, raise the air throughput by 52.43%.

We achieve a higher maximum power not only in the upper rev range: there is more power across the entire rev band. 

This also leads to a hugely improved throttle response at all revs, as the power graph below impressively shows.

• More power and increased torque across the entire rev band thanks to a better, faster and greater air flow compared with the standard air filter system
• Increased air volume thanks to the optimum intake capacity -> faster and more efficient cylinder filling
• Sportier and more aggressive intake sound
• Greatly improved throttle response
• In this way the air is passed on to the engine as cool as possible
• Product workmanship of the highest standard
• incl. expert report (therefore no registration required)

 

Scope of delivery:

Black powder-coated filter neck incl. HF-Series air filter (oiled) by Pipercross and all the necessary mounting parts + expert report

 

Oxygen is required to burn fuel. The more oxygen that reaches the engine, the more fuel can be injected, which in turn leads to a significant increase in power.
