APR's T2100001 K-04 kit includes a Borg-Warner K-04 turbo, the compressor inlet O-ring, four turbocharger to downpipe studs, one manifold to turbo gasket, a 4bar fuel pressure regulator, and one turbo to downturn gasket. This kit is a straight forward turbo swap that makes a big difference in the power output of the car.
APR's kit makes solid gains in both horsepower and torque. With no other mods than a Turbo-Back Exhaust, the APR T2100001 K-04 kit made 242hp/268lb-ft on 91 octane gas. Although the exhaust is not required, it is highly recommended.
