Dustin West dropped into the studio to discuss him and Ryan Wehrli of WCFab's week at the Sick Summer 2026! 800 miles of street driving to throw down over a week with 5 different days of drag racing. He recaps the ups, downs, and everything in between! If you're into diesel racing and the stories that come with them, you won't want to miss this episode.

Want the new 2007.5-2024 6.7L Cummins Fleece Performance Engineering Intake Horn and Grid Heater Kit without compromising the custom powder coat look? We’ve got you covered!

We can powder coat this kit to match your WCFab parts, like Gloss White shown here. This is a direct replacement, factory-appearing intake horn and high-flow intake plate that increases overall engine airflow and replaces the OEM-style grid heater with a robust coil-heating element.
