Catch Heat Shield

American Made Since 1985

Catch Heat Shield

Radiant Heat Protection Where It Matters Most.

Oil catch cans reduce oil vapor entering the engine through the PCV system, and this heat shield kit improves their efficiency by keeping the can cooler for better vapor separation.

Universal kit fits most oil catch cans and air-oil separators
Keeps catch can cooler so oil vapor condenses faster for improved separation
Includes heat-resistant edging tape for a clean, secure install
Reflects up to 90% of radiant heat for maximum thermal protection
Proudly made in the USA with high-quality materials

Automotive Heat Insulation for Your Oil Catch Can

The oil catch can in your vehicle is designed to “catch” oil vapor from the PCV system while the engine is running, preventing that vapor from being reabsorbed into the engine. When oil vapor escapes into the intake PCV system, it coats the intake ports, valves, and combustion chamber—leading to increased carbon buildup when burned. The result? Reduced engine performance, detonation (knocking), decreased air/fuel flow over the intake valves, and increased emissions.

Keep Oil Vapor Out of Your Engine with Catch Can Shield

Stop heat in its tracks with Heatshield Products’ Catch Can Shield. This innovative aluminum foil heat shield is engineered to keep your oil catch can cooler by blocking radiant heat from the engine and direct sunlight. Proven to reflect up to 90% of radiant heat, this high-performance automotive heat insulation withstands temperatures up to 1100°F continuous and 2000°F intermittent. Keeping the catch can cooler allows air entering the can to condense and separate oil vapor more efficiently—reducing the amount of oil pulled back into the intake system. This leads to cleaner intake valves, less carbon buildup, and reduced spark plug fouling.

Perfect for Dragsters and Open-Air Engine Bays

Using heat insulation for your oil catch can is especially critical for dragsters or any vehicle with an open-air engine compartment. The Catch Can Shield helps block both ambient engine heat and direct sunlight, keeping your system cooler and running cleaner. Installation is easy—just clean and dry the oil catch can, ensure the surface is at least 65°F, then stick on the heat shield. The sheet can be easily trimmed with heavy-duty scissors or a razor knife for a custom fit.
