Benefits and Practical Uses

Not only does it provide a significant power increase, but it also offers several practical advantages. Lower exhaust temperatures help maintain engine health and longevity, ensuring your vehicle remains robust on the road. The kit's compatibility with all 2003-2007 5.9L Cummins engines makes it a versatile upgrade for a wide range of vehicles. However, please note that this kit requires a Phatshaft with a 4 3/8" HE351 Large Flange or similar turbo. Additionally, it is not compatible with Steed Speed or AFE manifolds.
