MAR Motorsport – Europes Leading MAHLE Motorsport Pistons Distributor

MAHLE Means Performance

The undisputed technology leader in the piston field. With over 95 years of rich heritage MAHLE Motorsport pistons have won championships at all levels, including Formula 1 seasons with 16 out of 18 race wins supporting six of the ten teams, nearly two decades of straight wins at Le Mans, and championships in all three top levels of NASCAR®.

Slipper Skirt Style Forgings

strong, lightweight, low drag forging superior to the traditional full round design.

Ultra Flat Ring Grooves Increase Power

Every MAHLE Motorsport piston is machined to exacting tolerances with focused attention given to the radial flatness of the ring grooves. A flat ring groove is essential in achieving and maintaining the best seal possible. The quality of the ring grooves is so critical to peak and lasting performance, that MAHLE designed and built the machinery used to machine the ring grooves for its Motorsport piston assemblies.

True Performance Coatings 

MAHLE Motorsport proprietary Grafal® anti-friction skirt coating is like no other on the market. It is graphite impregnated to reduce drag like many other skirt coatings, but this is where the similarities end. The screen print application provides superior adhesion and is designed to last 100,000+ miles. The unique properties of Grafal® reduce the harsh contact between the piston skirt and cylinder bore, resulting in much less wear on the bore and significantly reduced piston skirt fatigue.

A dry phosphate coating provides the signature grey appearance to the MAHLE piston. This dry lubricant coating provides a lubricant film in the pin bores and ring grooves until the oiling system of the engine reaches operating pressure; particularly useful during initial start-up or break-in of engines to protect against galling and microwelding. The piston crown is still machineable.

Hard anodised ring grooves provide extra protection against ring groove microwelding for extreme duty applications.
