RB20 / RB20DET Billet Intake Plenum Kit – CNC Manifold + Throttle Body + Fuel Rail

In Stock – Ready to Dispatch from Our Auckland Warehouse

This listing is for a high-quality billet aluminum intake plenum kit designed to suit Nissan RB20 and RB20DET engines. Unlike low-grade cast manifolds that commonly leak or restrict flow, this kit is built for performance and durability.

CNC-machined runners, TIG-welded construction, and a polished finish make this intake not only functional but also visually clean for any engine bay. If you’re after a serious upgrade, this is the one to go for. Forget the cheap cast options—do it once, do it right.

Kit Includes:

• CNC-machined billet aluminum intake manifold (suits RB20 / RB20DET)

• 90mm billet throttle body

• Dual-feed fuel rail (suits top-feed 14mm injectors)

• Water line kit
