Plazmaman’s S14/15 Silvia Inlet Plenum is one of the most popular on the market for SR20 engines.
These manifolds utilize the factory cast aluminium runners, so not only do they allow for the well known SR20 strong mid range torque, but they are also extremely easy to fit. By bolting this manifold on and tuning the vehicle accordingly, we have seen up to 20rwkw – 30+rwhp gains. Of course, with the increased volume of this plenum, there is plenty more power to be made, especially when more boost pressure is fed into the engine.
Our inlet plenum comes manufactured to suit our billet CNC throttle bodies, in 60mm, 66mm and 72mm sizes. There is also an option to select none if you’re using your own throttle body, but we highly recommend using one of our throttle bodies to ensure the entry to the plenum is port matched, and has the flow capability to make the most of the plenum. We may need a drawing / flange plate if you wish to use another throttle body. *** FACTORY THROTTLE BODY CAN NOT BE USED – due to design and cable pull design ***
This plenum is compatible with the factory side feed fuel rail, or we have the option to run one of our billet CNC top feed rails, which converts to 14mm top feed injectors. Plazmaman fuel rails come in single or dual feed, with -8AN holes each end.
These manifolds can be supplied in 3 finishes, Raw, Polished, or powercoated Black, for the stealth look.
As with all Plazmaman inlet manifolds, these are packed with many features such as:
*** PLAZMAMAN also has a range of Flow matched fuel injectors available in the Fuel System Section of this online shop – these will make a great addition to your intake purchase . Any Injector you can not see please feel free to email/contact us, as we can source them ***
