Heavy-Duty Construction: The cold-rolled steel canister is designed to withstand high burst pressure and extreme vibration, preventing structural failure under heavy loads.
Precision Anti-Drainback Valve: Engineered with high-temp resistant silicone to keep oil in the filter after engine shutdown, eliminating harmful "dry starts."
