Chevrolet Silverado 3500 HD Intercooler - Mishimoto - 11+ 6.6L Duramax LML - Silver - 11-15. This Mishimoto intercooler is a direct-fit performance upgrade designed for 2011–2015 6.6L Duramax LML trucks, providing larger core volume and improved thermal management without fabricating custom mounts.
Built with cast aluminum end tanks and a bar-and-plate core, this intercooler addresses high intake and exhaust gas temperatures that can reduce power and risk component stress. The Mishimoto unit increases core volume and thickness over stock, improving airflow and lowering intake temperatures. It’s engineered to support substantial boost pressure for both stock and modified trucks and comes in a silver finish with Mishimoto’s Lifetime Warranty.
Features
- 101% increase in core volume versus factory
- Bar-and-plate core that is 73% thicker than stock
- Durable cast aluminum end tanks for strength and heat transfer
- Silver finish; direct-fit for 2011–2015 Duramax LML applications
