Anaheim-based European Auto Source, known for BMW aftermarket performance products, modifications, accessories, and service, continues their work on the BMW M3. For 2013, the tuning specialists are replacing the previous VF620 system with the ESS VT2-625 Supercharger.

With all the ESS systems they have been installing in the past 8 months, they needed to have one of their own to put to the test, in preparation for the heavy track schedule planned for this year.

Two versions will be released shortly, which will make it easier for those looking for individual-based runner methanol injection or auxiliary sensor mounting. Here is a comparison of ESS Intake Runner and the EAS one with the additional IAT/Boost sensors:
