The Wehrli driver-side 3" intercooler pipe for 2011–2016 Chevrolet 6.6L LML Duramax replaces the factory two-piece 2.5" pipe with a high-flow one-piece 3" unit. Finished in Illusion Purple, it includes upgraded silicone boots and T-bolt clamps rated for higher pressure and temperature, and works with the factory turbo or any drop-in style turbocharger to reduce restriction.
