EVIL ENERGY Oil Catch Can with Breather Filter
This universal oil catch can features a 300ml aluminum air oil separator tank designed to fit most cars with adequate installation space. It includes a versatile breather filter that can be installed for pre-PCV cars as a vent system or omitted when used inline between PCV hoses as a sealed catch can. The hose length is 2.6ft with a hose ID of 3/8″ and OD of 2/3″. The inlet and outlet threads are M16*1.5, ensuring a secure connection. This kit allows users to efficiently capture oil vapors and moisture to reduce carbon buildup and protect engine components.
EVIL ENERGY Baffled Oil Catch Can Kit with NBR Hose
This baffled oil catch can offers enhanced oil and moisture trapping capabilities through its removable baffle and steel wool filler. Designed universally with a 300ml capacity, it’s compatible with most vehicles that have sufficient room for installation. The kit includes a durable NBR fuel hose known for heat and wear resistance, sized at 2.6 feet long with a 3/8″ ID and 2/3″ OD. Ports use M16*1.5 threading. This catch can minimizes carbon buildup and helps maintain optimal engine performance.
K&N Air Oil Separator for Silverado and GMC Models
Specifically engineered for GM trucks and SUVs such as the Silverado 1500, Suburban, Tahoe, and Yukon models, this K&N Air Oil Separator effectively prevents engine oil contamination caused by blowby gases. It guards the intake manifold and combustion chamber against algae, sludge, and power loss associated with oil buildup. By filtering blowby vapors before they enter the engine, it helps maintain peak engine power and prevents premature detonation.
EVIL ENERGY Upgraded 300ml Baffled Oil Catch Can
This upgraded EVIL ENERGY catch can features a removable baffle and a low micron bronze filter to efficiently trap oil and moisture inside the 300ml aluminum tank. It is designed for the front of the PCV system and fits most vehicles with enough space. This system reduces carbon buildup to prevent misfires while keeping intake valves and pistons cleaner, ultimately extending engine life and preserving power.
EVIL ENERGY Air Oil Separator for Chevy Silverado and GMC Sierra
Designed to fit various Chevy Silverado 1500, Tahoe, Suburban, GMC Sierra 1500, Yukon, and Cadillac Escalade models, this compact 3oz oil catch can installs on the PCV side of the engine.

This air oil separator helps maintain clean intake systems and prevent engine damage by trapping oil and contaminants before they circulate
Buying Guide for Oil Catch Cans
Choosing the right oil catch can depends on several key factors that impact its effectiveness and compatibility with your vehicle. Here are important considerations when shopping for an oil catch can:
Capacity and Size
- Tank Size: Most catch cans range from 300ml to 750ml capacities. Larger tanks require less frequent emptying but need more installation space.
- Physical Dimensions: Ensure there is enough room in your engine bay for installation, including hose routing.
Compatibility and Fitment
- Universal vs. Vehicle-Specific: Universal kits fit most vehicles but check hose sizes and thread types (commonly M16*1.5) for compatibility; vehicle-specific kits like the K&N separator target certain models for optimal fit.
- PCV System Integration: Most catch cans connect to the Positive Crankcase Ventilation (PCV) system. Confirm whether it fits your engine’s PCV layout and location.
Design Features
- Baffled Design: Baffles inside the catch can enhance oil vapor separation and reduce liquid carryover.
- Filters: Some catch cans come with optional breather filters or upgraded filters like bronze mesh for superior trapping.
- Drain Valve or Dipstick: Convenient features make maintenance easier by allowing fluid level monitoring or quick draining.
Material and Durability
- Construction: Aluminum alloy is lightweight, corrosion-resistant, and durable for long-lasting service.
- Hoses: Heat and wear resistant hoses such as NBR or braided nylon extend reliability under engine heat and pressure.
Maintenance and Serviceability
- Ease of Cleaning: Removable baffles and filters improve cleaning ease and efficiency in maintaining catch can performance.
- Recommended Maintenance Intervals: Typically requires inspection and cleaning every 500-1000 miles depending on use, to avoid clogs and maintain function.
Selecting an oil catch can with the right capacity, fitment, and durable materials tailored to your vehicle and driving habits help ensure improved engine cleanliness, reduced carbon buildup, and sustained performance over time.
