Description for part number 111-8343

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%.

No one knows Cat Fuel Systems better than Caterpillar.
All Cat products come with a full 12-month warranty and off-the-shelf availability.
You're buying less downtime and lower repair bills, helping you achieve the lowest owning and operating costs over your engine’s lifecycle.
Cat diesel engine parts provide outstanding performance and reliability — while reducing the impact on the environment.

Warning:This product can expose you to chemicals including Lead and lead compounds, which is known to the State of California to cause cancer and birth defects or other reproductive harm. For more information go to www.P65Warnings.ca.gov.
