The APR Intercooler System is recommended and required to meet the advertised power levels.
Transmission
APR cannot make any guarantees as to the longevity of the OEM
manual transmission clutch or DSG/S Tronic clutches in every
transmission and therefore an upgraded clutch, such as APR’s upcoming
DSG Clutch Packs, are recommended and may be required depending on the stage, octane, driving style and clutch health. APR’s Stage III DQ250 TCU Upgrade is required for DSG / S Tronic models.
Engine Internals
Stage III power, torque, boost, cylinder pressure and
temperature levels and more are substantially higher than stock. APR
cannot make any guarantees as to the longevity of the factory engine
internals or all factory components on every engine. As such, APR
recommends upgrading rods/bearings and pistons/rings for increased
engine reliability and longevity, especially when using race fuel.
