The third-generation Chevrolet Silverado was offered with both 5.3L and 6.2L LS engines. These engines feature direct injection, which is great for creating an efficient burn and saving fuel but allows for carbon buildup on the intake valves.

As blow-by flows over the intake valves, oil and carbon deposits can build up, impeding airflow and eventually preventing the valves from closing. The best way to treat carbon buildup is to prevent it, and that's where this Mishimoto Chevrolet/GMC 1500 direct-fit catch can kit comes in.

This Mishimoto catch can kit diverts blow-by away from the intake and traps it in our catch can. Inside the can, a set of air turbulators and baffles separate fuel, oil, and water vapors from the crankcase gasses and collects them to be drained next time you change your oil. By not returning the blow-by to your oil pan, our kit prevents fouling of the oil that could reduce its effectiveness, leading to accelerated engine wear. Finally, a sintered bronze filter removes any remaining carbon from the crankcase gases so that only clean air returns to your intake.

The Mishimoto Chevrolet/GMC 1500 catch can kit is a complete bolt-on blow-by solution and includes all necessary components for a hassle-free installation. As with all our products, this kit includes our signature Mishimoto Lifetime Warranty.
