Fuel Injector Clinic 650cc Injector Set for VW / Audi (4 Cyl, 64mm) (High-Z) / IS165-0650H

VW Injector Set: 4x650cc Saturated / High Impedance Ball & Seat Injectors. These injectors utilize the latest technology and provide great linearity and short pulse width repeatability. Includes pigtails PGT USC4 or add Plug & Play adapters PADPUtoJ4

Fuel Injector Clinic injector sets are precisely flow matched to within 1%. Each injector within each set is individually numbered and results for each injector are listed on a detailed flow sheet included with the set. Dynamic flow matching is used only on injector sets where the additional time and cost are justified by the corresponding benefits gained during the tuning process.

Fuel Injector Clinic injectors are flow tested and rated at 43.5psi (3Bar) at 75??F average fuel temperature using CF-16B calibration fluid.

The superior spray pattern and atomization make these injectors easy to tune and provide great drivability.

Fuel Injector Clinic injectors are set up to and include all o-rings needed to fit the factory application for the listed vehicle. For aftermarket or other unusual setups please contact us prior to placing your order to make sure you receive injectors that fit properly.

Every injector is covered against failure caused by defects in original manufacture by our 12 month warranty.

Fuel Injector Clinic injectors use the factory electrical connector or include solder-in pigtails. You can purchase adaptor ????plug-n-play' harnesses to avoid cutting your stock harness as an optional extra.

This injector set contains high impedance injectors matched to the saturated injector signal generated by this vehicle's OEM ECU, OR is suitable for use with an aftermarket ECU made or set up for high impedance injectors.

This set of injectors requires you to change the injector plug on the wiring harness in your car. This can be done by soldering in the pigtails (included with purchase) to replace the plugs currently on your harness, or you can choose to purchase the optional plug-n-play adapters which will convert from the type of plugs on these injectors to the plugs on your harness without any need for cutting or soldering.

This plug conversion is made necessary because FIC always chooses to provide brand new, unused injectors for its performance applications. Since consistent fuel delivery is critical to high performance engine reliability we feel that using factory new injectors eliminates the increased potential for failure that exists when using remanufactured injectors.We do not believe that increasing the chance of a failure due to using remanufactured or core program based injectors is ever warranted.
