Opel 1.6L Z16LER / LET ZRP Forged Pistons

The Opel 1.6L Z16LET pistons are developed for mild to high tuning, mainly for road or club race cars that want to develop their engine for high mileage and/or street use. Designed by ZRP engineers and manufactured in Germany from 4032 (T6) high-silicon, low-expansion alloy. This allows the engine builder to run a closer piston to bore clearance thus producing a better seal. This minimizes the slapping noise during cold start, common place among engines running forged pistons, providing a quite operation and low oil consumption. We have chosen a Full round skirt design with bottom reinforcing band, with offset pins for quiet operation and the wrist pins are made from 9310 alloy. Other features include Anti-detonation grooves to protect the first rings, gas pressure accumulator groove for better ring seal and vibration relieve. Premium Japanese quality 1.00mm x 1.20mm x 2.80mm ring package included. Product Features and Design Anti-detonation grooves for long wear life and performance
