PC Racing Reusable Spin-On Oil Filter for Harley — Black Anodized, 35µ Stainless Mesh

The FLO PCS4B replaces disposable paper filters with a precision laser-cut, 304 stainless steel micronic mesh that offers far more filtration area and long-term durability. Its welded pleat seams resist heat, water and repeated cleaning; the stainless-media maintains strong oil flow at cold start and under extreme operating temperatures. Finished in black anodized housing with machined fins, this unit is designed to combine race-proven filtration technology with a premium look that complements Harley and other performance bikes.

How does this filter improve oil filtration compared with paper filters?

The FLO uses medical-grade 304 stainless micronic cloth that captures contaminants to about 35 microns — typically roughly three times finer than many quality paper or brass media. The larger total filter area created by the laser-cut mesh gives better flow and longer life between cleanings.

• Stainless mesh filters down to ~35 microns for finer capture.
• Up to 200% more active filter area versus common paper elements.
• Welded pleat seams withstand up to 600°F, unlike glued paper.
• Consistent flow under heat, water exposure and cold starts.

Is the FLO PCS4B easy to clean and reuse?

Yes — it’s designed for repeated service. Clean at every oil change using solvent, kerosene, contact cleaner or even dish soap; blow air from the inside out and lube rubber seals with fresh oil before reinstalling.

• Simple solvent or soap cleaning; air blow-out removes trapped debris.
• No adhesive pleats to fail — welded seams allow aggressive cleaning.
• Reusable design reduces landfill waste and long-term filter cost.
• Maintenance routine matches regular oil-change intervals for convenience.

Which bikes does this PC Racing spin-on filter fit?

The PCS4B fits a broad range of Harley-Davidson Twin Cam and earlier Evo models plus many European motorcycles listed by manufacturer and year. Check fitment against your specific model and year list to ensure compatibility before purchase.

• Harley: Touring/Twin Cam 1999–2013, Softail/Dyna Twin Cam 2000–2013, Evo models and Sportsters as specified.
• Buell: select M2, S3 and X1 models (mid-late 1990s to early 2000s).
• Selected Aprilia, BMW and Moto Guzzi models across model years shown in product listing.
• Direct spin-on replacement form factor for compatible engines.

What features support reliability and engine protection?

Beyond the stainless media, the filter includes design elements to sustain oil flow and capture metal particles. A bypass path maintains lubrication if the element becomes heavily loaded, and the magnetic prefilter collects ferrous debris before it circulates through the mesh.

• Integrated bypass ensures continuous oil delivery under restriction.
• Magnetic prefilter captures metallic particles to protect components.
• Billet-style black anodized housing with machined fins improves heat dispersion and appearance.
• Race-proven materials and construction used in motorsport and aerospace.

Who is this for: The PC Racing FLO PCS4B suits riders who want a durable, serviceable alternative to disposable spin-on filters — especially owners of compatible Harley-Davidson touring, Softail, Dyna, Evo and Sportster models and a range of European bikes who value high flow, finer filtration and reduced waste. It’s ideal for enthusiasts who perform routine maintenance, riders exposed to harsh conditions or high engine loads, and anyone seeking a long-term, performance-minded filter upgrade.
