common oil filter thread standards in the performance automotive world, used extensively by Honda and Acura across their B-series, K-series, F-series, H-series, and C-series engines. It is also used by Subaru on many of their EJ and FA\/FB series engines, as well as by other manufacturers. This broad compatibility makes the GReddy OX-01 a versatile choice for shops and enthusiasts who work across multiple Honda, Acura, and Subaru platforms. Always verify your specific vehicle's oil filter thread before ordering — while 3\/4-16 UNF is common, some applications use different thread standards.\u003c\/p\u003e\n\u003ch4\u003eFilter Dimensions — 65mm x 75mm:\u003c\/h4\u003e\n\u003cp\u003eThe OX-01's 65mm diameter and 75mm height are important fitment considerations beyond just the thread size. In some engine bays, particularly on modified vehicles with aftermarket components, filter clearance can be tight. Verify that a 65mm x 75mm filter has adequate clearance in your specific engine bay before ordering. If clearance is limited, a shorter filter may be required. Conversely, if your engine bay has ample space, a taller filter provides greater filter media surface area for improved filtration capacity and longer service intervals.\u003c\/p\u003e\n\u003ch4\u003eAnti-Drain Back Valve:\u003c\/h4\u003e\n\u003cp\u003eThe OX-01 includes an anti-drain back valve that prevents oil from draining out of the filter when the engine is shut off. Without this valve, oil drains back from the filter into the oil pan, leaving the filter empty. On the next startup, there is a brief period before oil pressure builds and the filter refills — during which the engine runs with reduced lubrication. The anti-drain back valve keeps the filter primed with oil, ensuring immediate oil pressure and lubrication on startup. This is particularly important for performance engines with tight bearing clearances where even brief oil starvation can cause accelerated wear.\u003c\/p\u003e\n\u003ch4\u003eOil Change Intervals:\u003c\/h4\u003e\n\u003cp\u003eReplace the GReddy OX-01 at every oil change. For performance and modified engines, more frequent oil changes are recommended — typically every 5,000 km or less depending on driving conditions and oil type. Track use, high-boost operation, and extended high-RPM driving all accelerate oil degradation and contamination, requiring more frequent changes. Always replace the oil filter at every oil change — reusing a filter allows contaminated filter media to re-enter the fresh oil charge.\u003c\/p\u003e\n\u003ch4\u003ePairing with GReddy MD-01 Magnetic Drain Plug:\u003c\/h4\u003e\n\u003cp\u003eFor comprehensive engine oil protection, pair the GReddy OX-01 oil filter with the GReddy MD-01 magnetic drain plug. The OX-01 captures non-metallic contaminants and larger particles through its filter media, while the MD-01's Neodymium magnet captures fine ferrous metal wear particles that can pass through the filter media. Together, they provide a complete oil filtration upgrade that protects the engine from both particulate contamination and ferrous wear debris — a simple, cost-effective combination for any performance build.\u003c\/p\u003e\n\u003ch4\u003eWhy GReddy?\u003c\/h4\u003e\n\u003cp\u003eGReddy (Trust Co., Ltd.) is one of Japan's most respected performance parts manufacturers, with decades of motorsport and street performance heritage.
