Fuel injection nozzles produce specific fuel spray patterns, a critical component of the fuel injection system, contributing to optimum combustion, emissions and fuel economy. Genuine Cat® Fuel Injection Nozzles are the best choice when you need to repair or rebuild any Cat diesel engine. Cat injectors are developed specifically for your Cat engine and today’s low-sulfur, low-lubricity fuels. We use specialized product metallurgy, proprietary manufacturing processes and design to bring you the best wear life, fuel economy and overall performance, regardless of the equipment it’s powering or the conditions it has to endure. Each unit undergoes extensive testing to ensure reliability and includes all critical engineering updates for optimum performance. That sets them apart from reverse engineered aftermarket brands, which can cause power and fuel efficiency losses of up to 5%.
