Chevrolet Silverado 3500 HD Intercooler Kit - Mishimoto - Duramax 6.6L LML - Silver - '11-'15. A complete intercooler upgrade engineered for Duramax LML 6.6L trucks, this Mishimoto kit reduces intake temperatures and improves airflow with durable components designed for heavy-duty use.

This kit includes a high-capacity bar-and-plate intercooler with cast aluminum end tanks, mandrel-bent aluminum piping, silicone boots with Mishimoto DuraCore reinforcement, and constant-tension T-bolt clamps. The intercooler core offers a substantial increase in volume and thickness versus the factory unit, allowing cooler, denser air to the engine which helps with thermal control under load. Pipes are polished mandrel-bent aluminum with a 3.5-inch cold-side and 3.0-inch hot-side to minimize restrictions. All necessary hardware is provided for a direct-fit installation on 2011–2015 Chevrolet/GMC 6.6L Duramax LML 2500/3500 HD trucks.
