Product Information

ESS Tuning is a name that has become synonymous with uncompromised performance in the BMW world. With over 2000 S65 supercharger systems sold since 2008, the E9x M3 S65 supercharger kit is by far the most popular BMW supercharger system worldwide.

The intercooled S65 G1+ Supercharger System produces a massive 180-220whp gain from stock depending on exhaust system and methanol injection used. It is supplied with both 93AKI/98RON and 93AKI/98RON + methanol injection pulleys as standard.

The G1+ kit improves upon the OEM intake manifold, adding in a custom cast aluminum manifold with optimized runners flowing into CNC’d aircraft-grade 6061 aluminum velocity stacks to smooth out airflow and reduce disruptive turbulence entering the throttle bodies, and is centered around the market’s largest liquid intercooler system. This ensures the intake charge temps remain in check during prolonged use on the track, autobahn, or street. The manifold was designed not only for optimum flow, but to be both aesthetically pleasing while keeping weight to a minimum to not disrupt the iconic handling balance of the M3.

The new ESS G1 supercharger head unit is by far the lightest high capacity supercharger in the industry weighing in at only 4.3kg and offering unparalleled efficiency, build quality and ultra low noise levels. However, what really sets the ESS S65 kit above all the others is our software tuning. For over 22 years, they've lived and breathed BMW’s, and it becomes apparent the second you sit behind the wheel of an ESS tuned car. The kit will include the ESS E-Flash OBD2 cable and specific ESS MSS60 engine software that has undergone over a decade of revisions to get perfected to where it is today. The E-Flash allows the end user to upload the supercharger ECU software from any PC running Windows 7 or newer and includes full diagnostic and code clearing capability. Any future ESS software updates can be received by email and loaded directly to the car. The stock ECU software will be saved and can easily be restored in the future.

The system maintains all OBD-II functions and it is backed by a comprehensive 2 year, unlimited mileage warranty program. The kit takes 8-14 hours to install using normal hand tools and no irreversible modification to the car is necessary.

The all-new S65 G1+ Intercooler Supercharge Package is a reflection of ESS Tuning's zero compromise approach to supercharging. Only the best quality components are granted a place in their kits and you can be sure it all fits with absolute precision. After development, the software and hardware are both vigorously tested, putting them through their paces on the street, track, and autobahn. Through this, ESS achieve reliability and quality that is on-par with the OEM themselves. This helps create the ever-desired OEM+ look for an appearance that says “take me out for a nice dinner, but don’t be afraid to use the back roads and let me loose on the way home.”

S65 G1+ Intercooled Supercharger System: Intercooled, 7.5-9PSI system compatible with manual and DCT E90, E92 or E93 M3. 93AKI/98RON or above required.

*HFC or cat-delete mid section recommended for optimal results. For off-road use only unless otherwise noted.



Note

This kit is designed for 93AKI/98RON fuel or above exclusively, in order to use the included high boost supercharger pulley a methanol injection system must be installed. ESS Tuning recommend the Snow Performance Stage 2 system using the #5 nozzle set to 3PSI start and 7PSI full gain. Torqo or VP methanol is recommended. We do not sell or support the methanol side of the system, so please ensure you find a competent supplier/technician with experience on these injection systems.

Fantastic customer service from the team at Southern BM. Expertly repaired my 2011 323i and did so without the attitude and excessive cost of a dealer. Thank you and I will be back for all future servicing.
