MKIV 1.8T K04 Turbo Upgrade

Our 1.8T kit includes the K04 turbo, the compressor inlet O-ring, four turbo to downpipe studs, one manifold to turbo gasket, 4bar fuel pressure regulator, and one turbo to downturn gasket. This kit is a straight foward turbo swap that makes a big difference in the power output of the car.

This kit makes solid gains in both horsepower and torque. With no other mods than an APR Turbo-Back Exhaust, the kit when installed on a MK4 1.8T made 242hp/268lb-ft on 91 octane gas, and 245hp/275lb-ft on 93 octane gas. Although the exhaust is not required, it is highly recommended.

If you are currently an APR Stage I or II customer and purchase a K04 upgrade, you will receive all EMCS options for free. The software for this kit is also available separately for current APR Stage I or II customers for $199 or $699 for new customers.

K04 APR Turbo upgrade

MKV GTI 2.0T K04 Turbo Upgrade

In typical APR fashion, the first turbo kit for the new 2.0T FSI engine provides a perfect balance of refinement and power. Making 300hp and 323 lb/ft, APR’s K04 turbo upgrade for the GTI 2.0T will enhance your driving experience without compromise. With smooth acceleration and flawless drivability, the APR K04 turbo upgrade will exceed all the demands of a daily driver while providing instant acceleration and an appreciably broader power band throughout the entire rpm range.

From the efficient and reliable KKK turbocharger and manifold assembly to the expertly re-calibrated engine management, APR’s K04 Turbo Upgrade offers performance and drivability that are perfect for the daily commute and week-end track event. Included as well, all the necessary hardware is OEM and helps maintain the stealthy fit and finish.

By incorporating OEM supplied components, we are able to ensure installation and service for your new transverse application will be as smooth as possible. Providing a direct replacement fit, the APR modified turbocharger and manifold assembly will mount in the exact location as your existing turbocharger and manifold assembly. This allows the use of all other OEM mounting locations for the such items as the exhaust and compressor inlet hose, making for a completely stealth installation. For best results, APR highly recommends using this kit with our Carbonio MKV Intake and APR Full
Exhaust system.
