Please note: Not all items are kept in stock. Lead times may apply contact us to confirm availability before ordering.

Description
These Adaptor Plugs are for those looking to add Nitrous, Methanol, or Water Injection to their CSF "No Limit" S58 & B58 Air-to-Air Billet Manifolds (CSF #8401 & #8402) or replace the port injection system on the CSF #8200, #8233, #8300, or #8400.
The Adaptor Plugs are based on the Injector Plugs but with an internal 5/16-24 threading to accommodate Nitrous Express Plate Jet Fittings (NX PN: 16149) for Nitrous, Methanol, or Water Injection. Using this size jet fitting eliminates the need for a separate nitrous nozzle and results in a more compact installation.
Note: Any 5/16-24 fitting will work with these adapters. CSF is currently working with Nitrous Express on a plug and play kit for the manifold that will be available in the near future.
