2003-2007 5.9L Cummins Stage 1 High Flow Intake Bundle Kit

Both intercooler pipes, one kit

Wehrli's Stage 1 bundle pairs its 3 in. passenger hot side intercooler pipe (WCF100544) with its 3.5 in. driver cold side pipe and matching 3.5 in. intake horn (WCF100528). Wehrli says the parts flow 60% better than stock.

Two 1/8 in. NPT ports are provided for boost readings or water-methanol injection, and the parts keep the factory dipstick location and wire harness routing. It bolts on to a stock truck with no tuning.

Who it's for

5.9L Cummins owners who want better charge-air flow without changing the intake.
