APR K04.3 GTS Turbocharger System Porsche 911 (991.2) Stage 3 ECU

APR K04.3 GTS Turbocharger System - Porsche 911 (991.2) - Stage 3 ECU

APR Tuning builds forced induction systems around genuine OEM engineering rather than aftermarket guesswork. The K04.3 GTS Turbocharger System (SKU T2100084) brings genuine Borg Warner K04.3 turbochargers, the same units fitted from the factory to GTS models, to your Porsche 911, unlocking the higher output hardware without touching the rest of the engine.

This listing covers the Porsche 911 (991.2) fitted with the 3.0T flat six. Because the base, S and GTS variants of the 991.2 share nearly identical engine architecture aside from the turbochargers, no other hardware upgrades are required to complete the conversion.

The kit includes the APR Stage 3 ECU upgrade, programmed onto your factory ECU from any lower APR stage at no additional cost, so the new turbochargers arrive fully calibrated.
