A fuel injector injects and delivers fuel to your engine's combustion chambers for proper burning. This is a small, electronically controlled valve that forces fuel through a nozzle and sprays it evenly toward the pistons. An even spray pattern and the right air/fuel mixture is necessary for efficient combustion, so you need a good fuel injector to ensure the precise amount of gas is delivered to the engine at all times.
Types of fuel injectors
You need to know the different types of fuel injector available in the market before finding the right one for your car. The throttle-body injector is the most basic type, and it functions more like a computerized carburetor. Located on top of the engine, it consists of a single injector that delivers fuel to all cylinders. A throttle-body injector is less precise than the other types, as it is the earliest fuel injection device to enter the market after the decline of traditional carburetors. Since it has only one injector, not all fuel may enter the cylinders. If you're the budget-conscious type, the throttle-body injector is the best choice because it costs less and is easier to maintain.
Multi-port fuel injectors are more advanced than single-port, throttle-body injectors. These injectors spray fuel simultaneously into the cylinders, and they are highly efficient in metering gas into the engine, resulting in better, more precise fuel delivery. Multi-port fuel injectors don't come cheap, but they do offer more power and greater fuel economy. If you want to enjoy these benefits, then you must be willing to pay the price and shell out more money.
Sequential multi-port fuel injectors are the most advanced and offer the most precise fuel delivery. Each injector is programmed to spray fuel to a particular cylinder right before it fires unlike the multi-port, which delivers fuel simultaneously. Quicker response, better fuel economy, and greater power per stroke are just some of the benefits of this type of injector. However, this can be quite heavy on the pocket, so you have to weigh the pros and cons first before purchasing it.
Fuel injector replacement cost
The simplest type of fuel injector is relatively cheap and may cost as low as $25. Depending on the brand and function, some fuel injectors may go over $100. Double this amount for labor costs if you don't plan on doing the repair and replacement yourself. For high-end vehicles, replacement and labor costs may go up to $300. If you want to save more money, purchase a fuel injector that fits your car's specs and follow the instructions on the installation manual. DIY repair is definitely the way to go if you want less expenses.
