Each new generation of engine is more capable than the last, but not every engine that goes out is as powerful as it could be. Even the new L5P Duramax engine needs some extra work if you want to get the most horsepower and torque out of it. At Norcal Diesel Performance, we can help you with our 2020–2021 L5P fuel system parts. We have everything you’ll need to get the most out of this engine.
We have the standard L5P fuel system parts you want, like a rail injection system cleaner, but we also have L5P fuel pump parts. And if you want more out of your fuel, consider some L5P Duramax fuel additives. The engine itself is high-quality, but if you want to take things to the next level, you can work with us at Norcal Diesel Performance!
