Start Of The Year Inventory Reduction Sale (only valid for existing inventory)!


  • EV14 Standard length - no spacers or adapters needed

    • ~53 mm or 2.09" O-ring to O-ring length

    • 64 mm or 2.52" overall length (end to end)

  • Connector type: USCar connector (sometimes referred to as an EV6 connector)

  • Resistance 12 Ohm (high impedance)

  • Spray pattern: 10 hole orifice plate, single cone pencil stream spray

    • 90% of mass in 10 degree cone (see images)

  • Maximum recommended pressure: 8.0 bar (116 psi)

  • Individually serial numbered and QR coded injectors for individual flow testing traceability

  • Compatible with most fuels including gasoline and ethanol (and flex fuel blends) and also compatible with water.

    • When used for water injection use of distilled water is required to achieve long term durability.

    • When used with methanol they must be flushed with gasoline after use.

  • Limited lifetime warranty (to original buyer)

Flow rate:

  • 9.13 g/s at 3 bar (43.5 psi)

    • 72.5 lbs/hr at 43.5 psi

    • 745 cc/min at 3 bar

  • 10.48 g/s at 4 bar (58 psi)

    • 83.2 lbs/hr at 58 psi

    • 855 cc/min at 4 bar (58 psi)


  • Eight (8) injectors + eight (8) additional lower O-rings for alternate intake manifolds

    • Includes pre-installed standard size outlet (manifold side) O-rings for use with intake manifold injector port/cup diameters of 13.6-14.0 mm (0.535-0.550"). Also included (but not installed) are larger diameter O-rings for use with GM LS2, LS3 & LS7 intake manifolds and other manifolds that have 14.5-14.8 mm (0.570-0.585") diameter injector bores. Note - failure to use the correct O-rings may result in intake manifold leaks and fuel trim/calibration/diagnostic issues.


  • Nostrum High Performance (NHP)

Part numbers:

  • NHP:    W065-0872

Country of origin: 

  • Designed, Manufactured & Tested in the USA


  • Brand new, flow tested and dynamically batched (as a set of 8)

  • These are NOT modified injectors. These are new injectors manufactured to the specifications shown in this description.

Direct fit for:

  • Applications that use EV14 Standard length injectors with a USCar connector and a single cone spray

  • 2005-2007 Corvette (LS2 engine)

  • 2006-2007 Cadillac CTS-V (LS2 engine)

  • 2005-2006 Pontiac GTO (LS2 engine)

Other fitment application notes:

  • These injectors are longer than the EV14 Compact injectors used in the LS3, LS7, LSA and LS9 engines. They are not a drop in fit for these applications. They can be used in these applications but you will likely need to space your fuel rail up or use an aftermarket fuel rail to use them.

  • Note these injectors are shorter than the LS1 & LS6 injectors and are not a drop in fit for those applications either.

Calibration notes:

  • Includes plug-and-play data for most GM, Ford & Chrysler ECU applications as well as Holley and other aftermarket ECUs. Please provide your email address and we can email you this data as a spreadsheet for you to copy and paste into your ECU file.

    • If you need help generating the ECU calibration file please contact us for assistance.

  • Most OEM GM ECU's prior to 2009 model year do not recognize injector flow rates above 8.0 g/s and not all ECU software sets after 2009 recognize above 8.0 g/s either. If using these injectors in applications that don't recognize flow rates above 8 g/s scaling of the injector flow, MAF and VE will be required. Check your ECU software or with your tuner before ordering if you are not comfortable scaling the variables needed.
