ZRP forged pistons for Volkswagen 2.0L TFSI / TSI with belt and chain drive, 82.50 mm, 9.6:1 compression ratio

The Audi/VW 2.0L TFSI pistons are developed for moderate to high-level tuning, primarily for street or club racing cars that want to develop their engine for high mileage and/or street use. Designed by ZRP engineers and manufactured in Germany using 4032 (T6) high-silicon, low-expansion alloy. This allows the engine builder to use smaller piston-to-wall clearances, resulting in a better seal. This minimizes cold-start slap noise, common in engines using forged pistons, providing quiet operation and low oil consumption. We have chosen a full-round skirt design with a bottom stiffening band, with oversized and deeper valve pockets to allow the use of high-lift camshaft profiles. They feature offset pins for quiet operation and the piston pins are made of 9310 alloy. Other features include anti-detonation grooves to protect the top rings, a gas pressure accumulator groove for better ring sealing, and vibration relief. Includes a premium Japanese-quality 1.00 mm x 1.20 mm x 2.80 mm ring pack.*Note: The pistons are designed to be used in all engine configurations with a 21.00 mm pin.
