When you own a Harley-Davidson, you know it’s more than just a bike—it’s a piece of art. To keep that masterpiece running smoothly, you need to take care of the engine. One of the most important parts of maintenance is choosing the right oil filter. A good oil filter will keep your engine clean and running strong.
Today, I’ll share my experience and insights on the best oil filters for Harley-Davidson motorcycles. Each one offers something different. Let’s dive in!
1. Harley-Davidson SuperPremium5 Oil Filter: The OEM Gold Standard
If you want a filter that fits perfectly and works well, the SuperPremium5 Oil Filter is a great choice. It’s made by Harley-Davidson for Harley engines. I’ve used it myself, and I trust it for its high quality. Here’s why:
Why I Recommend It

The Key Factors When Choosing an Oil Filter
Picking the right oil filter for your Harley isn’t just about grabbing one from the shelf. It’s important to understand the key factors that make a filter great. These factors will help you choose a filter that fits your needs and keeps your engine running smooth for years.
Let’s break down the most important specifications to look for when choosing a filter.
Filtration Efficiency: Micron Ratings Matter
The efficiency of an oil filter is one of the most important things to think about. It tells you how well the filter can clean your oil. The smaller the micron rating, the better the filter will capture tiny dirt and debris.
A micron is a very small unit of measurement. A human hair is about 40 to 90 microns wide. When choosing a filter, think about how well it captures particles.
- Nominal Micron Rating: This rating tells you what percentage of particles the filter catches at a certain size. For example, a 5-micron filter might catch 50% of particles that size. But this rating doesn’t always tell you everything.
- Absolute Micron Rating: This rating is more reliable. It tells you that the filter will catch 98.6% or more of particles at a certain size. This is a better way to measure how well a filter works.
When comparing filters, check if the rating is nominal or absolute. For example, AMSOIL EAOM134 has a 99% efficiency at 20 microns, which is great. K&N KN-171C, on the other hand, has a 25-micron nominal rating and only 3% efficiency at 5 microns.
Oil Flow Rate: Balancing Filtration and Flow
An oil filter doesn’t just need to clean the oil. It also needs to let enough oil flow to keep your engine running. If a filter is too dense or gets clogged, it might slow down oil flow. This can hurt the engine.
That’s why filters have a bypass valve. If the filter gets too clogged or the oil is too thick to flow, the valve opens. This lets oil bypass the filter and keep the engine lubricated. But unfiltered oil circulates, which isn’t great for the engine.
Some filters, like K&N and FLO, are designed to allow high oil flow. This is especially useful for riders who demand more performance from their bikes.
Filter Media: Paper vs. Synthetic vs. Stainless Steel
The material used in the filter is another important factor. Filters are made from either paper, synthetic material, or stainless steel mesh.
- Paper Filters: These are the most common and cheapest option. Harley-Davidson and WIX use paper in many of their filters. Paper filters work well for regular use and are affordable. But they might not last as long as synthetic filters.
- Synthetic Filters: AMSOIL and Harley’s SuperPremium5 use synthetic material. These filters last longer and capture smaller particles better. If you want a filter that lasts longer, this is a good choice.
- Stainless Steel Mesh: FLO PCS4 filters are made of stainless steel mesh. These filters are reusable. They’re durable and can be cleaned many times. They also allow high oil flow, but they cost more up front.
Bypass Valve: Keeping Your Engine Safe
The bypass valve is important. If the filter gets clogged or the oil is too thick, the valve opens. This allows oil to flow around the filter to keep the engine from starving for oil. But this means unfiltered oil is circulating through the engine, which can cause damage over time.
Different filters have different bypass pressure settings. For example:
- The WIX 57348 opens at 8 PSI.
- The K&N KN-171C opens at 14 PSI.
- The Harley-Davidson SuperPremium5 opens at 10 PSI.
The goal is for the bypass valve to open only when necessary. If it opens too often, it means the filter is too restrictive or clogged, which isn’t good.
Step-by-Step Guide to Installing Your Harley-Davidson Oil Filter
Installing an oil filter on your Harley-Davidson isn’t too difficult, but it does require some attention to detail. Whether you’re a first-time DIY mechanic or a seasoned pro, following the correct steps will ensure your oil filter works efficiently, keeping your engine clean and running smoothly.
In this section, I’ll walk you through the steps to install your oil filter properly. I’ll also cover some common mistakes to avoid during the installation process.
What You’ll Need:
Before you get started, gather the following tools and materials:
- New Oil Filter: Choose from the filters we discussed earlier, depending on your preference.
- Fresh Engine Oil: Make sure it’s the correct type and amount for your Harley model.
- Oil Filter Wrench: This is especially helpful for removing old filters.
- Clean Rag: Use it to wipe down the filter area and prevent any contamination.
- Rubber Gloves: To keep your hands clean and protect them from hot oil.
- Pan or Container: To catch any old oil when removing the drain plug.
- Torque Wrench: To ensure the filter is installed at the right tightness.
Step 1: Drain the Old Oil
Before you can change the oil filter, you’ll need to drain the old oil. This ensures that no contaminated oil remains in the engine, which could affect performance.
- Locate the Oil Drain Plug: For most Harley-Davidson models, the oil drain plug is located at the bottom of the oil pan.
- Place a Drain Pan: Position a drain pan beneath the oil drain plug to catch the old oil.
- Remove the Plug: Use a wrench to carefully unscrew the oil drain plug. Let the oil drain completely, which can take a few minutes.
Step 2: Remove the Old Oil Filter
Once the old oil has drained, it’s time to remove the old filter.
- Use an Oil Filter Wrench: The filter is usually tight, so you’ll need an oil filter wrench to loosen it. Place the wrench around the filter and turn it counterclockwise to remove it.
- Check for Leaks: After removing the filter, inspect the filter area for any oil leaks or leftover debris.
Step 3: Prepare the New Oil Filter
It’s important to lubricate the gasket of your new filter before installing it. This will ensure a proper seal and make it easier to remove the filter next time.
- Lubricate the Gasket: Apply a small amount of fresh engine oil to the rubber gasket of the new filter. This helps the gasket form a good seal when installed.
- Inspect the Filter: Check the new filter to ensure it’s the correct model for your Harley. Make sure there are no damages or defects.
Step 4: Install the New Oil Filter
Now that the new filter is ready, it’s time to install it on your Harley.
- Screw the Filter On: Carefully screw the new filter onto the oil filter mount by hand. Turn it clockwise until the gasket touches the mount. Be careful not to over-tighten it.
- Hand-Tighten: Most manufacturers recommend tightening the filter by hand and then giving it an additional 3/4 turn. If you’re using a filter with a 17mm wrench-off nut (like the K&N KN-171C), you can use a socket wrench for added convenience. Just be sure not to overtighten.
Step 5: Add Fresh Oil
With the new filter in place, you’re ready to add the fresh oil.
- Check Your Oil Capacity: Refer to your Harley’s manual to know how much oil you need to add. The amount will vary depending on your bike model and engine size.
- Pour the Oil: Slowly pour the fresh oil into the oil fill cap. Use a funnel to prevent spills.
- Check Oil Level: After adding oil, use the dipstick to check the oil level. Add more if necessary, but avoid overfilling.
Step 6: Start the Engine and Check for Leaks
Once the oil and filter are installed, it’s time to fire up your Harley.
- Start the Engine: Let the engine run for a few minutes to allow the new oil to circulate and fill the filter.
- Check for Leaks: After turning off the engine, check around the filter for any signs of leaks. If you see any, carefully tighten the filter or check the gasket for proper placement.
Step 7: Dispose of the Old Oil and Filter Properly
Proper disposal of used oil and filters is crucial for the environment.
- Dispose of Used Oil: Take the old oil to a local recycling center or auto parts store that accepts used oil. Many stores, like AutoZone and O’Reilly Auto Parts, offer free oil recycling services.
- Recycle the Old Filter: The old filter can often be recycled. If the filter is made of steel, you can take it to a metal recycling center.
Common Mistakes to Avoid During Installation
While changing your oil filter is straightforward, there are a few common mistakes to watch out for:
- Over-tightening the Filter: This is one of the biggest mistakes you can make. Over-tightening the oil filter can damage the gasket or make it difficult to remove the filter later.
- Skipping the Lubrication: Failing to lubricate the gasket on the new filter can lead to poor sealing, which might cause leaks.
- Not Checking for Leaks: Always run the engine and check for leaks. This step ensures that everything is properly sealed and working correctly.
- Using the Wrong Filter: Make sure you’ve chosen the right filter for your Harley. If the filter doesn’t fit properly, it could lead to oil leaks or poor filtration.
