Set of 8, 25lb, High Performance Fuel Injectors fits 2007-2013 Volvo Penta 5.7L . TLF Performance Fuel Injectors are nationally known for quality and precision. Our High Performance Fuel Injectors are counted on by racers and enthusiasts every weekend, while our OEM Replacement Fuel Injectors are used on everything from recent classics to late-model vehicles that need a quality replacement injector. Our fuel injectors are special because they are remanufactured using only stainless steel or titanium internal moving components, each injector's integrated filter is replaced with a premium 20μm brass filter, and all o-rings are replaced with Viton™ nitrile rubber o-rings. We also rigorously test every injector for precise fuel flow before it’s shipped, simulating both race and street use. Every injector is also also pressure tested for leaks, and we include testing documentation with each injector so you can see the test results for yourself. All our injectors are remanufactured in Eldorado, Illinois, from premium quality OEM injector casings. NOTE: When installing new high performance fuel injectors in your vehicle, you may need to update ECU tuning and/or upgrade other fuel system components. Also, the injectors you receive may not be the same color as those shown in the image. Injectors may also have original markings that do not reflect the actual specs of your injector - be sure to review the included test results if you have questions about flow rate.
