RB25DET front facing plenum to OEM throttle body adapter

This kit allows you to bolt the factory RB throttle body to a Greddy (or Greddy style) front facing plenum. The factory throttle body will support 700+ hp with ease. No more air leaks from using a poor quality aftermarket throttle body. This will allow you to replace the common Chinese 80mm throttle body, or a Nissan Q45 throttle body

-Bolt centres on the plenum side = 78mm x 78mm

-Bolt centres on the throttle side = 78 x 63mm
