2.5 TFSI EA855 evo Forged piston set JE

Forged high-performance pistons from JE Piston for all 2.5L TFSI EA855EVO engines in the Audi RS3 8V and TTRS 8S.

With the forged pistons set from JE-Pistons it is quite easy to reduce the compression ratio and at the same time get more power and durability. The engine also runs smoothly during the cold start phase and the special alloy of the piston enables low running clearance.

The compression ratio of these high-performance pistons is ideal at 9.5:1 or 10.0:1. The special ring zones ensure low blowby so that no power is lost.

Features:

• new, exclusive piston design especially for 2.5L TFSI EVO engines
• adapted ring zones and improved piston rings
• Low running clearance possible thanks to special alloy
• Smooth engine running even in cold start phase
• High performance piston pin with 22mm & 23mm
• Ideal compression ratio of 9.5:1 or 10.0:1 and optimum piston shape for 2.5L TFSI engines
• for standard bore 82.50mm and if minimal honing is required also in 82.55mm
• Low blowby due to special ring zones
• Complete set incl. piston pin, rings and clips
• Installation and drilling dimensions included

The specified compression is in conjunction with a series cylinder head gasket with 1.40mm thickness.

Ultra Series:
The piston of the Ultra series combine all the premium features of JE and the brand new technology of the forging industry! JE's revolutionary Perfect Skirt coating is one of the many technologically advanced aspects of the Ultra Series. It protects the piston skirts, reduces friction and prevents cold start piston slap and false knock.

All Ultra Series piston are supplied with a ceramic crown coating as standard to ensure longer life and better exhaust gas cleaning properties. Thicker piston pins made of premium material are another feature of the Ultra series, and combined with the unique Grain Flow Optimised forging technology, the Ultra series is ready for tremendous performance.
