Fuel injectors deliver the right amount of fuel at the right time into an internal combustion engine. Cat® Fuel Injectors are the best choice when you need to repair or rebuild any Cat diesel engine. Cat Fuel Injectors are developed specifically for your Cat engine and today’s low-sulfur, low-lubricity fuels. You’ll get the best wear life, fuel economy and overall performance, regardless of the equipment it’s powering or the conditions it has to endure. Featuring coated plungers for maximum wear resistance, each unit is rigorously tested, so you know you’re getting genuine Cat reliability. That sets them apart from reverse engineered aftermarket brands, which can cause power and fuel efficiency losses of up to 5%.
