Sinister Diesel - Cold Air Intake for Cummins

The engine bay of a Cummins diesel truck is a tough environment. It’s full of heat that can rob power and performance. To get the coldest and densest air into your engine, you need a diesel cold air intake. Not only is a diesel cold air intake one of the most common and least expensive performance modifications you can make, but it is also one that brings the most benefit because cool, dense air holds more oxygen leading to better combustion, more power output, and better fuel economy from your Cummins engine.
