Honda OEM Oil Filter - S2000 F20C / F22C Engines You're doing an oil change on your S2000 and you want the factory filter that Honda designed for the F20C or F22C. This is genuine Honda OEM part 15400-PCX-306. It's the correct spin-on filter for every S2000 from 2000 to 2009. AP1 cars with the F20C. AP2 cars with the F22C. Same filter works on both. The filter mounts on the engine and catches contaminants in your pressurized oil before it heads through the bearings, VTEC system, and all the oil passages. You're getting the factory-spec filtration. No guessing. No mystery media. Just the filter Honda engineered for your motor. Available as a single unit or a 6 pack if you're doing multiple oil changes or you want to stock up. Here's What the Filter Does The oil filter is a full-flow spin-on design. All your engine oil flows through the filter before it goes to the bearings and the rest of the engine. The filter media catches particles and contaminants so they don't get circulated through the engine. The filter's got an internal bypass valve so if the filter gets clogged cold oil can still flow to the engine. The filter's also got an anti-drain-back valve so oil doesn't drain out of the filter and back into the pan when the engine's off. Both valves are built into the filter. You can't service them separately. You replace the whole filter at each oil change. That's the way Honda designed it. That's the way you keep it running correctly. Replace It Every 5,000 Miles - Honda Says So Honda recommends an oil change every 5,000 miles or 6 months on the S2000. That means a new filter every 5,000 miles. The S2000's a high-revving motor. The F20C and F22C are pushing 9,000 RPM regularly. The oil's working hard. The filter's working hard. Fresh oil and a fresh filter every 5,000 miles keeps the engine healthy. If you're tracking your car or running at high RPM all the time replace it more often. Don't try to stretch the oil change interval on an S2000. The engine's not going to tolerate neglect. Replace the filter when you change the oil. Every time. Torque It to Spec - Don't Hand Tighten It This is the thing people get wrong. The filter's not just hand-tight. Honda specs this filter to 15-18 ft-lbs. Use a filter socket and a torque wrench. Tighten it to spec. Don't overtighten it. We've seen people crank on the filter like it's a lug nut. The gasket gets crushed. The can gets damaged. The next oil change you're fighting with a stuck filter. You're cursing because you overtightened it. Undertighten it and the filter weeps oil all over your subframe. You're getting a slow seep that makes a mess. Get it right. Use 15-18 ft-lbs. Pre-oil the gasket lightly before you install it so it seats evenly. Then torque it to spec. Honda OEM Filter - The Right Part This is genuine Honda OEM part 15400-PCX-306. It's the filter Honda installs on S2000s at the factory. It supersedes the older 15400-PCX-004 if your parts counter or service record shows that old number. Same filter. Updated part number. The media's engineered for F-series oils and flow rates. The anti-drain-back valve's the right stiffness. The bypass valve's the right pressure. The threads are M22 x 1.5 and they match the filter boss on your engine perfectly. Aftermarket filters are cheaper. Some are fine. Some are junk. We've seen cheap aftermarket filters that don't flow right. The bypass valve opens too early and cold starts get poor oil pressure. We've seen filters that collapse under pressure. We've seen filters where the anti-drain-back valve doesn't work right and oil drains back into the pan. The S2000 engine is tight and precise. It doesn't need mystery filtration. Buy the Honda filter. It's engineered for your engine. It flows right. The valves work right. You install it once and you're done.
