AUDI A4 B8 1.8 TFSI 120hp CDHA 2008-2015 

The AUDI A4 B8 1.8 TFSI 120hp with the CDHA engine, built from 2008 to 2015, uses the four-cylinder EA888 block of the VAG group. This page gathers the reinforced engine parts we list for that engine. One reference is online today: the 1.8L 16v EA888 forged piston kit, offered by WÖSSNER at the standard 82.5 mm bore for a 9.2:1 compression ratio, and by JE PISTONS bored to 83 mm for a 9.6:1 ratio. The lower ratio is the usual choice as soon as boost pressure goes up. Valves, connecting rods, head gasket and bearings are not listed for the CDHA to date.
