Mercedes-Benz A45 CLA45 GLA45 AMG Power Pack Upgrade: 4-Inch K&N Cold Air Intake & Billet Underdrive Pulley Kit

Upgrade both the airflow and engine response of your Mercedes-AMG with our complete Planet Parts Power Pack.

Designed specifically for the turbocharged A45, CLA45 and GLA45 AMG, this package combines our 4-inch cold air intake kit with our lightweight billet aluminium underdrive crank pulley kit.

The larger intake helps the turbo breathe more freely, while the lightweight underdrive pulley reduces rotational mass and the power required to drive the engine accessories. Together, they provide a sharper, more responsive driving experience with increased induction sound and improved performance.

Power Pack benefits:

• Increased airflow through a large 4-inch intake
• Genuine K&N High-Flow Performance Pod Filter
• Reduced intake restriction
• Increased turbo and induction sound
• Reduced rotating mass
• Improved throttle response
• Reduced parasitic load from engine accessories
• No ECU tune required
• Direct-fit components designed specifically for these AMG models

4-Inch Cold Air Intake

The factory air intake inlet is upgraded from approximately 2.6 inches to a much larger 4-inch inlet, allowing the turbocharger to draw air through a genuine K&N high-flow pod filter.

The intake housing is CNC-machined from billet aluminium, sandblasted internally for a smooth finish and anodised black for a neat, factory-style appearance.

Installation requires no cutting or permanent modifications and can generally be completed in approximately 20–30 minutes.

Billet Underdrive Crank Pulley

The factory heavy cast-iron crank pulley is replaced with our lightweight underdrive pulley, reducing rotating mass and slightly slowing the operation of the engine accessories. This allows the engine to respond more freely and directs more available power towards driving the vehicle.

Manufactured from CNC-machined 6061 billet aluminium, the pulley is finished in black anodising and features a hardened stainless-steel hub ring for a strong and reliable seal against the crankshaft.

A correctly sized Gates drive belt and a new genuine Mercedes-Benz crank bolt are included.
