Description

Mahle high performance piston for 2.5L TFSI engines (as in Audi RS3 and TTRS)

With this high-performance forged piston set from MAHLE Motorsport, it is quite easy to lower the compression ratio while getting more power and durability. The engine also runs smoothly in the cold start phase and the special alloy of the piston allows for low running clearance.

The compression ratio of these high performance pistons is ideal at 9.6:1. The special ring zones ensure a low blowby so that no power is lost. With these piston even extreme power increases are a breeze!

Features:

Especially for 2.5L TFSI engines
Low running clearance possible thanks to special alloying
Smooth engine running even in cold start phase
High performance piston pin 21mm (standard 22mm)
Ideal compression ratio of 9,6:1 and optimal piston shape for 2.5L TFSI engines
Also available in standard bore 82,50mm
Low blowby due to special ring zones
Anti-Friction graphite coating
Mahle High-Performance piston rings

All piston sets are supplied with high-strength piston pins and complete ring sets.

The Mahle forged pistons are an optimal complement to our H-Shaft steel pistons.
