Why upgrade

It's been over a decade since the last 1999-2003 7.3L Powerstroke rolled off the assembly line. A lot can happen to a vehicle in that much time. And, if you're like many 7.3L Powerstroke owners, you've been through more than one degas tank. Mishimoto engineers these kits around real chassis packaging, so hoses, coolers and adapters line up without fabrication on the listed years. Follow the published torque specs and install guide, reuse sensors where instructed, and confirm clearances if you run other supporting mods. Every unit ships with the Mishimoto Lifetime Warranty for as long as you own it.
