SR20 DET S13 Billet Inlet Manifold

Plazmaman's SR20 S13 (Red Top) inlet manifold is designed with curved inlet runners.

The first option is a full billet runner version which is designed to fit into any S chassis and some other versions from nissan.

The second option is a custom runner version, which allows for modification to the runner length to suit different applications as these engines are commonly transplanted into older vehicles. As these older engine bays are quite tight, the Plazmaman S13 SR20 Inlet has adjustable runners. We can simply shorten, or lengthen the runners to suit your conversion or needs. We can tack together the setup and send it to you for test fitting first. Please Contact Us for further information.

We highly recommend the use of our Billet 66mm or 72mm throttle body for street/strip/drift applications, or for high-end race vehicles, the 85mm is recommended. This manifold is supplied complete with a dual feed fuel rail, with -8AN holes each end.

These Intake manifold can be supplied in 3 finishes, Raw, Polished, or powder coated Black, for the stealth look.

As with all Plazmaman intake manifold, these are packed with many features such as:

• • 2 options of intake runners. 
  • 6061 T65 Aluminium.

  • Precision CNC machined billet base, with hand made 3mm smooth design plenum dome.
