- If you have ever dropped one down in the black hole of the engine compartment, you know what we are talking about. The design of these things is pretty awful. These are EV1 connectors, so there are some better replacements out there, but depends on how far you want to go into new wiring.
Cleaning Fuel Injectors
You can see from the picture below, just one example of fuel injector cleaning and balancing. We normally take injectors to RC Engineering in Torrance, California. They have been working on injectors for us for over 20 years. We nearly always notice a much smoother idle and less small pops and stumbles with a cleaned set of injectors. Not sure about how often to clean injectors, but 25 years seems to be well within reason. This helps a lot with emissions.
You can see that with cleaning, the fuel injectors can safely supply from 316 hp to 411 hp of fuel, vs 249 hp to 324 hp prior to cleaning. If you let fuel injectors sit for too long, they can lock up, so we do recommend hitting them with 12 volts prior to installation. Or if you install them, and have a hard misfire, check each injector that it isn't stuck. An injector is just a solenoid. So it needs a power and ground, hooked up either way to energize and move. You can hear and feel the solenoids in the injectors move when you energize them. We also recommend OEM fuel injector o-rings over the o-rings that RC supplies. Their top o-ring(green) is designed for an 11mm rail, and does not like fitting in a stock 10.5 mm rail.

| 1000 cc drop in replacement fuel injectors for a Nissan Skyline GT-R. |
Drop in 1000cc injectors, does not mean that you don't have to tune them. It just means that you don't have to get all crazy with the fuel rail or other parts to make the fuel injectors fit. These will supply enough fuel for about 900 hp at the engine on gasoline. More information on E85 requirements and injectors can be found in the Fuel System post below.
