Precision Fuel Injectors

Upgrading fuel injectors is a necessity when modifying or changing exhaust headers, throttle bodies, fuel systems or cylinder heads. That's why it's important to insist on the best. Each Precision fuel injector is flow checked, individually scribed, hand selected and then carefully matched to within 1% of each other for optimum performance in your vehicle. All horsepower ratings are calculated at 90% duty cycle at 43.5 psi upon a BFSC of .50. Compatible with all known aftermarket drivers.
