Forged piston kit JE for 2.5L TFSI Audi RS3 8V & TTRS 8S E855 DAZA & DNW

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 piston set from JE-Pistons it is quite easy to lower the compression ratio and at the same time get more power and durability. The engine also runs smoothly during cold starts and the special alloy of the piston allows for low running clearance.

The compression ratio of these high performance pistons is ideal at 9.5:1 & 10,0:1. The special ring zones ensure low blowby so as not to lose power.

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 alloying
• Smooth engine running even in cold start phase
• High performance piston pin 22mm or 23mm
• Ideal compression ratio of 9.5:1 (ultra series) or 10,0:1 (normal) and optimal piston shape for 2.5L TFSI engines
• for standard bore 82.50mm and if minimum 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 are included

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

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

All piston Ultra Series pistons come standard with a ceramic crown coating to ensure longer life and better emission control characteristics. Thicker premium material piston pins are another feature of the Ultra Series. Combined with the unique Grain Flow Optimized forging technology, the Ultra series is ready for tremendous performance.
