Phearable.net offers a full line of precision injectors to it's customers.
We have used precision's injectors in setups ranging from 200 whp all motor cars to 800+ whp turbocharged applications.
Precision injectors have proven to be very reliable & perform extremely well when put through harsh race conditions.

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.

Part Number	Flow Rate	HP Per Injector	Impedance	Resistance
042-0310	310cc	55	High	12 ohm

* Low impedance injectors require a resistor box or inline resistors.
* High impedance injectors do not require a resistor box.
* 92-00 Civics & 94-00 integras do not use a resistor box from the factory.
* Vehicles without a resistor box can have one installed, vice versa.
* Precision injectors do not properly fit in JRSC intake manifold or 92 & older factory sohc intake manifolds & some first gen b16 intake manifolds as the injector tip is too large to clear the injector inlet.
 

* Precision injectors work with obd1 & obd0 honda injector clips.
* Obd2 vehicles require precision injector clips.
