ZRP RODS – PISTONS SET VW 1.4L TFSI 2012-PRE

The Audi/VW 1.4L TFSI and TSI pistons are designed for moderate to high-performance tuning, primarily for road racing or club cars looking to develop their engines for high mileage and/or street use. Designed by ZRP engineers and manufactured in Germany from a high-silicon, low-expansion 4032 (T6) alloy. This allows the engine manufacturer to use a tighter piston-bore clearance, resulting in better sealing. This minimizes the slapping noise during cold starts, common among engines using forged pistons, ensuring quiet operation and low oil consumption.
We chose a round-skirt design with a lower reinforcing 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 wrist pins are made of 9310 alloy. Other features include anti-knock grooves to protect the first rings, and a gas pressure accumulator groove for improved ring retention and vibration reduction. A premium Japanese-quality 1.50 mm x 1.20 mm x 2.20 mm ring is included.Product Features and DesignAnti-knock grooves for long life and high performanceGas pressure accumulator groove in the second ring for increased wear resistance.Horizontal slots in the pin hole designed to allow oil to penetrate between the pin and the pin hole area.Precision CNC machined ring groovesHigh-silicon/low-expansion 4032-T6 alloyHoned pin holes3D piston head specifically designed for the needs of TSI combustion chambersFull-round skirt with lower reinforcement band for high HP/boost applicationsValve pockets designed to accommodate oversized valves and high-revving camshafts liftPistons designed to optimize squish for longer engine life and increased power potentialOptional coatings offered upon request”Blast Off Bronze” Thermal Barrier Coating”Stealth Black” Moly Side-Skirt and Under-Crown CoatingAdditional InformationApplication 1.4L TFSI (2012-previous)Bore Size 76.50 mm , 77.00 mmWeight Gr 233, 236Stroke 75.60 mmOffset Ratio 10.0:1OEM Offset Ratio 10.0:1Height 29.00 mmRod 144.00 mmPin Diameter 19.00 mmDeck Clearance -0.20CCS Dome -8.5ccRing Set 765XPZ, 770XPZWrist Pin Pn Model WP141-SP
