JE Piston Ultra Series 1.8T 20V Piston VW Golf 4 Audi S3 TT

JE Pistons forged pistons for the 1.8 20V Turbo

Made in USA

Optimize your 1.8T 20V racing engine with our JE Ultra Series forged pistons.
Thanks to the high-quality 2618 aluminum alloy, the pistons are lighter, stronger and more temperature-resistant as well as more resilient than standard pistons.
The compression is reduced. This allows significantly higher pressures to be run than with the standard pistons. Even excessively high boost pressures of up to 3.5 bar are no problem with a sensible tuning and corresponding engine setup.

It should also be noted that the webs between the piston rings are 5-8 mm wide (instead of only 3-5 mm as with other pistons).
