Note: Always verify your vehicle uses the 3/4-16 UNF oil filter thread before ordering. Confirm filter dimensions (65mm diameter, 75mm height) provide adequate clearance in your engine bay. Replace at every oil change. Lightly lubricate the filter gasket with fresh oil before installation — hand tighten only.

Pro Tip: Pair with the GReddy MD-01 Magnetic Drain Plug for complete oil system protection — the OX-01 captures particulate contamination while the MD-01 captures fine ferrous wear particles.
