Our Porsche 911 Stage 3+ Kit builds on the baseline of the Stage 3 Kit but adds key hardware/supporting modifications and custom tuning to exploit the power potential of the GTS turbos. With the GTS turbos in place, we leverage the BMC High Flow Air Filter. Porsche utilizes the BMC High Flow Air Filters on the 991 GT3 RS and 918 models from the factory. Their more efficient filter media promote higher airflow into the engine. An optional modification is the IPD Plenum which helps promote higher air velocity to the engine and can enhance power further. For our Stage 3+ Power Kit, we recommend the AMS Intercooler Kit. This is the premier intercooler kit on the market and has everything in the kit including some nice carbon fiber shrouds that replace the factory plastic bits. These intercooler cores are 50% larger than the OEM intercoolers and allow for better heat dissipation which lowers the Intake Air Temperatures (IATs). This helps stabilize the intake charge temps making more power at greater efficiency. These Porsche 911 Stage 3+ power kits are a must have for someone who tracks the vehicle or wants to add some additional cooling to the vehicle.

On the exit of the turbo, we replace the factory link pipe that integrates a very dense and restrictive catalyst with a higher flowing design. This not only increases exhaust flow but it allows heat to extract off the turbochargers. These upgraded link pipes have a few options and considerations but reduce weight while increasing power and sound. With this change, you'll experience some more cracks and aggressive tones from the exhaust (particularly in sport/sport plus mode) without introducing resonance or drone to the cabin. If you are looking to enhance power a little more while adding more sound, we also offer a variety of muffler sections which provide an enhanced driving experience. Because the OEM diverter valves are prone to leaking with higher boost levels and over the long term weaken and crack, we leverage the EVOMS Diverter Valves that feature a machined aluminum construction for superior performance and durability.

Tying this all together, we partner with ByDesign, the most experienced and leading tuning calibrator in the 911.2 Carrera and 991 Turbo models. With years of co-development on many builds, the tuning will bring the full potential of this set-up to fruition while maintaining high-reliability and daily driving capability. We recommend utilizing the Cobb PDK tune as well to help optimize the transmission for the larger power output. While not required, it will sharpen the driving experience and reduce shift times out of the already impressive PDK dual clutch transmission. Our Stage 3+ Power Kit delivers extremely similar power to a 991 Turbo with the same bolt-ons and tuning. Compared to a stock base Carrera, you will reduce your 0-60MPH figure by 0.8 seconds, drop 1.5 seconds off the quarter mile run while your trap speed increases by 15MPH! These are impressive results that transform the dynamics of the vehicle.
