WEHRLI CUSTOM FAB WCF100682 2011-2016 DURAMAX LML PASSENGER SIDE 3.5 IN. INTERCOOLER PIPE

Product Description

Improve boost flow and reliability in your 2011-2016 Duramax with the WEHRLI CUSTOM FAB WCF100682 3.5" PASSENGER SIDE INTERCOOLER PIPE. The factory LML intercooler piping is restrictive and prone to failure under higher boost levels, especially on tuned or modified trucks. Wehrli Custom Fabrication designed this upgraded intercooler pipe using mandrel-bent 3.5-inch aluminum tubing to increase airflow capacity while delivering superior durability.

This high-performance intercooler pipe replaces the factory passenger-side charge pipe and provides smoother airflow between the intercooler and intake system. The larger diameter tubing helps reduce boost restriction and improves turbo efficiency, making it an ideal upgrade for tuned trucks, upgraded turbo setups, or high horsepower builds.

Frequently Asked Questions

What does upgrading the intercooler pipe improve?

A larger diameter intercooler pipe allows more air to flow from the intercooler to the engine, reducing restriction and improving turbo efficiency.

Is this pipe larger than the factory charge pipe?

Yes. The Wehrli WCF100682 pipe increases diameter to 3.5 inches which improves airflow over the smaller factory pipe.

Will this work with a stock turbo?

Yes. This intercooler pipe works with the factory LML turbo as well as many aftermarket turbo upgrades.

Do I need custom tuning for this upgrade?

No tuning is required to install this pipe, though trucks with performance tuning will benefit most from the increased airflow.

Is this a direct bolt-on upgrade?

Yes. The pipe is designed as a direct replacement for the factory passenger side intercooler pipe on LML Duramax trucks.
