Description
The Mishimoto MMBCC-T1-19 is a direct-fit catch can kit purpose-built for GM’s T1 platform, the chassis underpinning the 2019+ Chevrolet Silverado 1500 and GMC Sierra 1500 along with their SUV siblings. Because these trucks run direct-injected 5.3L L83 and 6.2L L87 V8 engines, blow-by gases can carry oil and carbon deposits directly onto the intake valves, and this kit is Mishimoto’s engineered answer to that problem. At its core sits a 6061-T6 billet aluminum, twist-off catch can with an internal air diverter, baffle, and sintered bronze filter that separate fuel, oil, and water vapor from crankcase gases before they ever reach the intake tract.
Rather than letting blow-by recirculate into the intake or foul the oil pan, this Mishimoto catch can kit diverts crankcase gases into the can, where turbulators and baffles trap contaminants for easy draining at your next oil change. A 50-micron bronze filter scrubs remaining carbon from the gases so only clean air returns to the intake, helping guard against the power-robbing carbon buildup that direct-injection engines are prone to and reducing the chance of blow-by contaminating the intake mixture. Keeping oil and carbon out of the intake and out of the crankcase oil supports cleaner combustion and helps protect engine oil from the fouling that can accelerate wear.
