Harley-davidson Oil Filter Chart
The Harley-Davidson Oil Filter Chart is your go-to resource for identifying the correct oil filter for every Harley model, from vintage bikes to modern touring cruisers. Using this guide ensures proper lubrication, prevents contaminants from harming your engine, and keeps your ride running smoothly.
Key Takeaways
- Model-Specific Filters: Not all Harley-Davidson filters are universal; always match the filter to your bike’s year, model, and displacement (e.g., 103ci, 114ci).
- OEM vs. Aftermarket: Original Equipment Manufacturer (OEM) filters like Harley-Davidson PF-7 or aftermarket options like Wix 57289 offer similar quality but may vary in price.
- Change Frequency: Replace oil filters every 5,000–10,000 miles or per manufacturer’s schedule, depending on riding conditions.
- Installation Tips: Tighten by hand plus a quarter-turn (no over-tightening!), and use an oil filter wrench if needed.
- Signs of Failure: Check for leaks, excessive pressure, or reduced oil flow—these indicate a bad filter needing immediate replacement.
- High-Mileage Considerations: For older Harleys, consider a high-capacity or extended-life filter (like Fram Ultra Blue) to handle more contaminants.

Why Your Harley-Davidson Needs the Right Oil Filter
Your Harley-Davidson’s engine runs hard, whether you’re cruising down the highway or hitting twisty backroads. The oil filter plays a critical role in keeping everything clean and functioning efficiently. A mismatched filter can lead to premature wear, increased friction, or even engine failure. That’s why we’ve compiled the ultimate Harley-Davidson oil filter chart to help you find the perfect fit for your ride.
The Role of an Oil Filter
An oil filter acts as a sieve, trapping dirt, metal shavings, and other harmful particles that circulate in your engine’s oil system. Over time, these contaminants degrade oil quality, leading to:
- Increased engine temperature
- Reduced fuel efficiency
- Wear on internal components
Using the wrong filter compromises this protection, which is why precision matters so much.
Common Mistakes to Avoid
Many riders skip checking their filter compatibility or reuse old ones—both are big no-nos. Always:
- Verify your bike’s make, model, year, and displacement (e.g., 103ci, 114ci)
- Don’t reuse old filters—they lose sealing power over time
- Don’t over-tighten (use a wrench if needed but follow torque specs)

Filter Options Explained
- PF-7 (OEM): Harley’s standard design; reliable but often pricier than aftermarket alternatives.
- K&N HP-103: Great for performance builds; high-flow design reduces resistance.
- Fram Ultra Blue: Budget-friendly with good capacity; ideal for casual riders.
- Purolator PF7: OEM-compatible; trusted name for durability.
How to Choose Between OEM and Aftermarket Filters
While OEM filters are guaranteed to work perfectly, aftermarket options can save money without sacrificing quality. Here’s how to decide:
Pros of OEM Filters
- Perfect fit: No risk of leaks or installation issues.
- Manufacturer-backed warranty: Hassle-free replacements if defective.
- Consistent performance: Ideal for stock setups.
Pros of Aftermarket Filters
- Cost savings: Brands like Wix and Fram offer comparable quality at lower prices.
- Specialty features: Some come with anti-drain valves, longer service intervals, or enhanced materials.
- Compatibility: Many fit multiple Harley variants (e.g., Wix 57289 works for Softails and Touring models).
If you’re unsure, try a reputable afterbrand first. For high-mileage Harleys, motor oil for high mileage vehicles paired with a heavy-duty filter (like Fram Ultra Plus) can extend engine life.
Proper Installation & Maintenance Tips
A filter installed correctly makes all the difference. Follow these steps:
Step-by-Step Guide
- Park on level ground: Drain oil easily if done properly.
- Remove old filter: Use a wrench (see how to remove without a wrench if space is tight).
- Lubricate new filter gasket: Apply fresh oil to prevent leaks.
- Tighten properly: Hand-tighten, then add a quarter-turn—never overtighten!
- Check for leaks: Wait a few minutes before restarting.
Maintenance Schedule
- Racing/off-road: Change every 2,500–5,000 miles.
- Daily commuting: Every 5,000–7,500 miles.
- Long-term storage: Replace before riding again.
Signs You Need a New Filter
Watch for these red flags:
- Oil leaks around the filter base
- Engine noise (knocking/grinding)
- Oil pressure warning light
- Unusual smoke (blue/grey) from exhaust
Ignoring these symptoms can lead to costly repairs. If you’re struggling to remove a stubborn filter, refer to wrench alternatives.
FAQs About Harley-Davidson Oil Filters
What’s the difference between a full-flow and bypass filter?
Full-flow filters handle both oil and fuel contaminants, while bypass systems only protect the oil. Harley-Davidson uses full-flow designs exclusively.
Can I use a motorcycle oil filter on my Harley?
No—motorcycle and automotive filters have different housings and pressure ratings. Stick to bike-specific filters like PF-7.
Do I need a filter wrench?
Not always. If the filter isn’rusted and fits by hand, a wrench isn’t necessary. But tight or corroded filters benefit from one (tightening tips apply too).
How do I know if my filter is clogged?
Check oil pressure gauges or look for sluggish acceleration. A clean filter restores performance instantly.
Are high-performance filters worth it?
For modified Harleys, yes. High-flow filters (like K&N) reduce resistance and improve horsepower. Stock riders won’t notice a difference.
Where can I buy authentic Harley-Davidson filters?
Genuine parts are available through dealerships or online retailers like Amazon, RockAuto, or Harley-Davidson’s official store.
