About this part

Product Details

Wehrli Custom Fabrication is known for making well-built performance parts for diesel trucks. If you're working on your 2011-2016 Duramax LML, this passenger side intercooler pipe is a solid upgrade over the factory plastic piece. It's designed to help your turbocharger breathe easier, which can lead to improved throttle response and quicker turbo spool-up.

This pipe is made from 14-gauge aluminum and features a larger 3.5-inch diameter compared to the stock pipe. It uses high-quality silicone boots and stainless steel t-bolt clamps, which are much better at holding higher boost pressures than the original equipment. This helps prevent leaks and potential failures, especially if you're running a modified truck. The factory intake temperature sensor can be reinstalled using the included threaded bung, and it's designed to work with your stock Y-bridge and crossover pipe, making installation straightforward with basic hand tools.

This pipe is a direct bolt-on upgrade that doesn't require any additional modifications, tuning, or upgrades to install. For best results, it pairs well with emissions-compliant tuning and drop-in turbochargers.
