Chevrolet Silverado 2500 HD Intercooler Kit - Mishimoto - Duramax 6.6L LML - Silver - 2011-2015. This complete Mishimoto intercooler kit is built for owners running the 6.6L LML Duramax in 2011–2015 Silverado 2500 HD models who want a durable, higher-capacity charge-air system.

The kit replaces the factory cooler and piping with a larger bar-and-plate intercooler featuring cast-aluminum end tanks and mandrel-bent aluminum pipes to improve flow and reduce intake temperatures under load. Components are engineered to resist heat, pressure, fuel, and oil exposure, and the silicone boots use Mishimoto’s DuraCore material with constant-tension T-bolt clamps to maintain secure connections. The design supports increased boost tolerance and helps lower EGTs when towing or running higher power levels without overstating results.

Features

• Bar-and-plate core with cast aluminum end tanks
• 101% increase in core volume and 73% thicker core vs. factory
• Mandrel-bent aluminum piping (3.5" cold-side / 3.0" hot-side)
• Mishimoto DuraCore silicone boots and constant-tension T-bolt clamps
• Offered in Silver finish and backed by Mishimoto Lifetime Warranty
