Three upgrades in one kit
Wehrli's Stage 2 bundle packages three of its 5.9L Cummins parts: the 4 in. air intake (WCF100346), the 3 in. passenger hot side intercooler pipe (WCF100544), and the driver-side 3.5 in. cold pipe paired with a 3.5 in. intake horn (WCF100528).
They are made in the USA from mandrel-bent 14 ga tube and CNC-machined billet parts to replace aging, leak-prone factory pieces. Wehrli says the cold side upgrade flows 60% better than stock, helping spool, throttle response and exhaust temperatures. The kit works with stock or drop-in Holset turbos and OEM-style intercoolers.
Who it's for
5.9L Cummins owners pushing past stock power who want the full intake path upgraded.
