15-20 Chevy Tahoe 6.2L Catch Can

The 15-20 Chevy Tahoe 6.2L Catch Can by CORSA PERFORMANCE is an air-oil separator designed to address one of the most common issues facing modern direct-injection engine builders and enthusiasts: excessive crankcase vapors that accumulate in intake manifolds. As a mechanic, you know that factory PCV systems on 6.2L powerplants can't handle the volume of oil mist generated during high-boost conditions, aggressive driving, or modified engine tune scenarios. This catch can intercepts those vapors before they reach your intake valves, preventing carbon buildup, intake valve fouling, and the performance degradation that follows.

Engineered with a 3-ounce capacity and constructed from black anodized aluminum, this separator delivers reliable separation efficiency in a compact 9.5 x 6.9 x 12.4-inch footprint that fits tight under-hood configurations typical of GM fullsize trucks and SUVs. The dual 3/8-inch NPT female inlets and outlets provide straightforward plumbing integration without adapter complexity, while the 2.375-inch diameter and 3.625-inch height allow flexible mounting in available engine bay real estate. The aluminum construction resists corrosion from acidic vapors and condensation, and the anodized finish maintains appearance through years of thermal cycling and direct underhood exposure that would degrade lesser catch cans.

This catch can suits any 2014–2020 Chevy Tahoe, Suburban, or Sierra HD owner running the 6.2L engine who wants to protect their investment through preventive crankcase management. Installers appreciate the straightforward NPT port configuration, which eliminates the need for barbed fittings or braided line complications on aftermarket setups. Whether you're tuning for towing capacity, building a daily-driven performance platform, or simply maintaining long-term engine health in a stock vehicle, separating oil mist from intake charge delivers measurable improvements in combustion cleanliness and reduces the frequency of carbon cleaning interventions over the vehicle's service life.
