2020 Porsche Application Guide

MAHLE’s relationship with Porsche dates back to Porsche’s beginning. Together we have developed some of the best competition and sports car engines available throughout the last nine decades. MAHLE Motorsports North America has taken the extensive experience gained from its relationship with Porsche to develop a series of performance and racing piston and cylinder kits. These kits were designed for high performance applications and are modern adaptations of the original or aftermarket kits; therefore there may be visual differences that are intentional and beneficial to the performance, durability and longevity of the components.

Porsche Aircooled Piston and Cylinder Assembly Instruction Manual

MAHLE Motorsports North America has taken the extensive experience gained at the OE and motorsports levels to develop a series of performance and racing piston and cylinder kits. These kits were designed for high performance applications and are modern adaptations of the original or aftermarket kits; therefore there may be visual differences that are intentional and beneficial to the performance, durability and longevity of the components. The pistons are machined from forgings with narrower and shorter skirts to reduce weight and friction. The cylinders included in Motorsports air-cooled kits are produced and machined to original equipment tolerances, designed to provide increased performance, durability and longevity. Some applications are available as either a slip-in or machine-in design. The slip-in cylinders are simply a larger internal bore replacement. The machine-in cylinders require the engine cases be machined to a larger bore diameter to accept their larger spigot diameter. The larger spigot diameter is preferable for extreme applications as with highly boosted turbo or competition use engines.

Porsche PowerPak+ Piston Kits

MAHLE Motorsport's PowerPak and PowerPak+ piston kits offer superior reliability and performance, letting you take your build to the next level. Backed by over 95 years of performance experience and using MAHLE manufactured machinery to offer advanced features found nowhere else, make no compromises, trust MAHLE Motorsport.

Advanced Features

Slipper Skirt Style Forgings: strong, lightweight, low drag forging superior to the traditional full round design.

Phosphate Coating: helps prevent microwelding in the ring grooves and pin galling.

Gold Series® Anti-Friction Skirt Coating: MAHLE's proprietary skirt coating that's compatible with Honda factory FRM cylinders, therefore eliminating the need to sleeve the block; reduces drag, scuffing, friction, cylinder bore wear, and reduces piston noise.

Hard Anodized Top Ring Grooves (PowerPak+ Piston Kits): extra protection against ring groove microwelding for extreme duty applications.

2618 Aluminum Alloy: whether building a street engine or an all out race engine, both 4032 and 2618 alloys are available depending on the application.
