What Do Injectors Do?

As one might suspect, Fuel Injectors inject fuel into the car’s motor. Older vehicles used carbs that mechanically supplied the fuel into the motor, while in newer vehicles, the ECU controls the fuel injectors, electronically. The ECU, or Electronic Control Unit, calculates sensor info from areas like the exhaust system and internal engine parts to carefully measure and inject fuel into the engine for efficiency and max power. A dirty injector won’t release the correct fuel amount.

Replacement Schedule for Injectors

In normal driving conditions, the Fuel Injectors should be changed every 50-100k miles. At least, that is what some published reports suggest, but the actual replacement interval may be very different, based on a multitude of factors. If you drive more than 1000 miles a month or live in an extreme climate, you want to replace the fuel injectors more often. Modern injectors are more robust than previous models and should boast several years of service. Regular maintenance and injector cleaning can help prolong the lifespan past 100k miles.

How Much Does It Cost To Replace Fuel Injectors?

The price of changing out dirty injectors may be as little as $200-300 dollars. In these situations, the car is simple to work on, and the replacement parts are not very expensive. On the other hand, if you have a car imported, and the parts are difficult to find, then the final bill to replace the injectors will be higher. Even if you like working on your car, this is an item you might want to leave to the professionals. We have the specific tools and computers to help ensure the correct installation of your injectors.
