18- Jeep Wrangler 3.6L Catch Can

The CORSA PERFORMANCE 18-Jeep Wrangler 3.6L Catch Can (CC0002) is an air-oil separator engineered to protect your engine by capturing blow-by gases and oil vapor before they enter the intake system. This catch can prevents oil accumulation in the intake manifold, reducing carbon buildup and extending engine longevity on both street and off-road applications. Designed specifically for the 3.6L engine in 2018–2025 Jeep Wrangler JL and 2020–2025 Jeep Gladiator models, it delivers measurable protection with minimal installation complexity.

This air-oil separator features a 3-ounce capacity with a 2.375-inch diameter design that fits easily into the engine bay without interfering with other components. The 3.625-inch height and 3/8-inch NPT female inlet and outlet connections allow straightforward plumbing integration into existing PCV systems. Constructed from aluminum with a durable black anodized finish, the catch can resists corrosion and UV degradation—critical for vehicles exposed to salt air, mud, and harsh terrain. The compact footprint means installation does not compromise under-hood space or require extensive modifications.

Jeep Wrangler and Gladiator owners running stock or modified 3.6L engines benefit from catch can installation to maintain fuel economy, reduce intake valve deposits, and lower oil consumption issues common in higher-mileage vehicles. Off-road enthusiasts who regularly expose their rigs to aggressive conditions find that blow-by capture keeps intake systems cleaner during extended trips. Weekend warriors and daily drivers alike see the value in preventive engine maintenance that requires no tuning, no ECU reprogramming, and no warranty complications—just bolt-on protection.
