JE 301941 Piston Kit (83.50 mm Bore, 1.165 in. CH, 7.70 CC) for VW 9A 16V 2.0L Engine ymm_82 Ester base stocks and friction ymm_43 Ester base stocks and friction modifiers (except NS) provide additional slipperiness to lower operating temperatures by reducing the sliding friction in hypoid gears Too much pressure drop can of course have a problem on the higher performance engines as the intercooler reaches its maximum efficiency the turbo has to work a lot harder to force the air through the core these pistons are Designed for each specific engine and racing application to provide durability and performance and machined 100% in the USA
