Evolve Supercharger Uprated Billet Plenum - BMW 5 Series E39 M5

Description

The reason we have made the plenum is not just for improved efficiency, but to facilitate not blowing plenums up or seeing even the strongest ones expanding and contracting so much (they eventually blow too).

The plenum has been designed on purpose with the location of the the two entry feeds to be in the stock position meaning that it can be installed on any supercharger kit that uses the OEM plenum, such as RK and ESS

The construction is all Billet CNC machined and is 4 pieces:

• Bank 1 and 2 throttle body connectors / first half of velocity stacks
• Lower base plate with second half of velocity stacks and directional air channels (equal distribution of air)
• Top reinforced lid
