Katch was from the company GMC.

The catch can's main function is to reduce the accumulation of oil and residues that come from oil vapor inside the intake system. This helps improve engine performance and keeps the valves and the system clean overall, especially in modern engines that use direct injection systems. The features of the catch can include: 1. Reducing carbon buildup: prevents oil and residue deposits on the intake valves, especially in engines with direct injection systems. 2. Improving engine performance: keeps the fuel-air mixture clean, contributing to better combustion and more efficient performance. 3. Extending engine life: reduces wear and friction caused by the accumulation of oil and residues inside the engine. 4. Lowering harmful emissions: helps reduce emissions resulting from oil combustion inside the combustion chamber. 5. Easy maintenance: provides an easy way to monitor the amount of captured oil and dispose of it. The catch can is a great investment if you care about your car's performance and maintaining the engine for a longer period.
