Frequently Asked Questions
Are these injectors a set of four?
Yes. This listing includes a complete set of 4 injectors.
Will these injectors work with my factory ECU?
These injectors use a saturated, high impedance design for broad ECU compatibility, though tuning may be required to match the increased flow rate.
Do these injectors require a tune?
Yes. A proper tune is recommended to match fuel maps to the increased injector flow rate for optimal performance.
Are these injectors compatible with OBD I and OBD II engines?
Yes. These injectors are designed to be compatible with both OBD I and OBD II B, D, and H Series engines.
Do these injectors include new O-rings?
Check the package contents at installation. New O-rings are recommended for a proper seal regardless of injector age.
What fuel types are these injectors compatible with?
These injectors are designed for use with gasoline fuel systems.
Can these injectors be used on a stock engine?
These injectors are intended for modified engines with increased fuel demands and may require tuning even on otherwise stock engines.
Is professional installation recommended?
Professional installation and tuning is recommended to ensure proper fuel delivery and engine performance.
Installation Instructions
