ZRP forged pistons for Volkswagen / Audi 1.4L TFSI 2012-Earlier, 19mm pin, 77.00mm, 10.0:1

Audi/VW 1.4L TFSI and TSI pistons are designed for moderate to high engine tuning, primarily for street or track vehicles looking to optimize performance for high mileage or road use. Designed by ZRP engineers and manufactured in Germany using 4032 (T6) high-silicon, low-expansion alloy, they allow engine builders to work with tighter piston-to-wall clearances, resulting in better sealing. This minimizes cold-start slap noise, common in engines with forged pistons, providing quiet operation and low oil consumption.

We have opted for a round skirt design with a bottom reinforcing band, featuring oversized and deeper valve pockets to allow for the use of high-lift camshafts. They feature offset pins for quiet operation, and the piston pins are manufactured from 9310 alloy. Other features include anti-detonation grooves to protect the top rings, a gas accumulator groove for improved ring sealing, and vibration relief. Includes a set of premium Japanese-quality piston rings measuring 1.50 mm x 1.20 mm x 2.20 mm.

Product features and design

Anti-detonation grooves for increased durability and performance.
Gas accumulator groove on the second ring land for increased durability.
Horizontal grooves in the pin bore designed to allow oil entry between the pin and the pin bore.
CNC-precision machined ring grooves.
