Wehrli Custom Fab Stage 2 High Flow Bundle for 2020–2025 Duramax L5P trucks, finished in Illusion Blueberry. The kit replaces restrictive factory plastic intake and intercooler pipes with 4" and 3–3.5" aluminum piping, upgraded silicone boots, stainless t-bolt clamps and a dry-filter airbox with pre-filter cover. It eliminates weak factory joints, bolts on to stock trucks without modifications, and the 4" turbo inlet has been shown to yield a 25 HP gain when paired with Wehrli’s Max Effort tune.
