JE Pistons Audi TT RS 5-Cylinder Piston Kit 9.5:1 – High-Performance Forged Pistons

Description

Upgrade your Audi TT RS with the JE Pistons Part Number 337966, a premium forged piston kit designed for high-demand racing and performance applications. Crafted from high-strength 2618 aluminum and fully manufactured in the USA, these pistons are engineered to withstand extreme conditions on the track or street. The kit includes five pistons, each with a 3.248-inch bore, a 9.50:1 compression ratio, and an inverted dome/dish design optimized for performance. Engineered specifically for the 5-cylinder engine, these pistons deliver a perfect balance of durability and power. The proprietary Forged Side Relief (FSR) forging minimizes friction and power loss by reducing skirt width and saving weight with a shorter wrist pin. An accumulator groove (application-dependent) helps reduce pressure from combustion gases, which enhances ring seal and promotes consistent power delivery. The skirt coating (application-dependent) reduces friction and wear, extending piston life and lowering operating noise. These pistons are equipped with high-quality wrist pins, locks, and JE’s premium Pro Seal piston rings, ensuring reliable performance under demanding conditions. Designed for easy installation and maximum performance, this piston kit is an ideal upgrade for enthusiasts seeking to improve engine power and longevity while maintaining OEM-like reliability. Fully compliant with Prop 65 standards and made with attention to detail, the JE Pistons Audi TT RS kit is a top choice for professional racers and automotive enthusiasts alike.
