Get that slightly wrong and the engine knows immediately - a rough idle, a hesitation off the line, a cylinder that just won't pull its weight. We stock fuel injectors for gasoline and diesel engines across a wide range of vehicles, listed with OE and interchange numbers so you can match the one in your engine with confidence, and we ship worldwide.\u003c\/p\u003e\n\u003cp\u003eInjectors don't fail gracefully. A clogged or sticking injector usually announces itself with a misfire, a smell of fuel, or a check engine light, rather than fading out slowly the way some other parts do. Catching it early and replacing the right part saves you from the knock-on damage a badly running engine can cause over time.\u003c\/p\u003e\n\n\u003ch2\u003eTypes of Fuel Injectors\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003ePort fuel injectors\u003c\/strong\u003e spray into the intake runner just before the valve, at comparatively low pressure.
