K&N Vs Wix Oil Filter- Which One is the Best For Your Engine?

An oil filter is one of the most important parts of your car’s engine. The function of an oil filter is to remove impurities from the engine oil before it reaches critical moving parts in the engine, such as bearings or pistons.

These moving parts rely on a thin film of oil for lubrication, and if this film becomes contaminated, it can cause wear and ultimately failure.

Oil filters usually consist of a paper or cloth filter element that traps contaminants as oil flows through it. Some filters also have a metal screen or magnet to capture even smaller particles. There are different oil brands, including K&N and Wix oil filters.

While all filters serve the same purpose, different brands offer varying quality, and so it’s essential to know the distinguishing factors between these two brands. Let’s get started.

As far as oil filters go, there are a few different brands that stand out from the rest. In this article, we’ll compare two of the most popular brands on the market – K&N and Wix.

Off-road drivers will find K&N oil filters to be a lifesaver. These filters are designed to filter large quantities of oil efficiently. They handle boats and even godsend for owners of classic cars. You’re not alone if you’re wondering who produces K&N oil filters. K&N Engineering, Inc. produces k&n oil filters and they are located Riverside, California, United States of America.

Before leaving the factory, each K&N oil filter undergoes laboratory testing to verify it meets the highest performance, capacity, and bursting strength criteria. Here are few reasons why we believe the K&N oil filter is better.

  • A valve made of silicon rubber prevents oil drainback. Double-rolled high quality seals and a durable canister help in ensuring long-lasting functionality by limiting oil loss.
  • Instead of reliance on single-use plastic filters that harm our environment, K&N recyclable engine filters offer a sustainable, long-lasting, and cost-effective alternative.
  • Regardless of the type of oil in your vehicle is synthetic, conventional, or a combination, you may use these oil filters with just about any type of oil. For instance, K&N Performance Gold oil filters filter your engine’s oil to the highest quality. Keep contaminants smaller than 10 micrometers out of your engine.

Are they good?

Wix is a remarkable high-quality filter that uses high-quality materials and stands out from the competition. Mann and Hummel were the owners and manufacturers of the German multinational corporation Wix Oil filters.

Where are Wix oil filters manufactured? Wix has factories on four continents, including North America, Europe, Asia and South America, and its headquarters are situated in Gastonia.

Below are some of the reasons why Wix oil filters are considered one of the best in the market today.

Quality Materials: By replacing metal pieces with new plastic elements, Wix was able to reduce the size of the filter while maintaining its quality. This is how the bulk of a filter may be reduced while filtering quality is maintained. Using a glass-enhanced media, the filter for synthetic motor oil catches 10-12 micron particles.

The brand maintains product quality via routine laboratory testing. The OEM-specified, springs, valves, and housings of the filter can survive harsh conditions. For example, their racing oil filters are made using quality components to increase speed.

Spin on Filters: The criteria for spin-on filters must match those of the engine or car manufacturer. Wix oil filters function properly in oil systems due to their composition.

Custom Valves: The design and features of spin-on filters must conform to the engine or car manufacturer’s specifications. Custom-made to the needs of each individual client, Wix oil filters work efficiently in an oil system.

K&N vs. Wix Oil Filters Comparison


When it comes to performance, there’s really no clear winner between K&N and Wix. Both brands offer high-quality filters that will do a great job of protecting your engine.

K&N oil filters are designed to trap more dirt and debris than other brands, making them ideal for high-performance applications. Wix oil filters are also effective at trapping dirt and debris, but they may not be able to keep up with the demands of a high-performance engine.

Wix’s filters are designed to trap 99% of harmful contaminants, and they also have a lifespan of up to 15,000 miles.

In addition, K&N oil filters flow more freely than Wix oil filters. This means that they allow your engine to breathe easier and run more efficiently. As a result, your car will have more power and better fuel economy.

Filtration media

All through process of filtering, the filter media gathers any unfiltered oil particles. The oil filters manufactured by Wix utilize synthetic media. K&N oil filters are optimal for race vehicles that require thicker oil. Additionally, the oil-changing interspace is a constituent of the oil filter. With 15,000 miles intervals between changes, Wix is the best in this scenario.

Drifting Oil

Take into consideration the oil flow before buying an oil filter. Drifting oil allows oil to bypass filters that are blocked. K&N oil filters have a faster flow rate than Wix due to their racing nature, making them ideal for high-performance engines. Typically, a greater flow rate indicates a less effective filter material. Wix collects 95% of particles at 20 microns, whereas K&N only removes 85%. The oil pressure release valves of K&N oil filters are made of steel springs, and the filter’s pressure drives the spring down to open the bypass valve.

Backup drain valves

Wix oil filters are fitted with silicon anti-drain back valves for a smooth vehicle startup. In contrast to plastic or rubber anti-drain back valves, Wix anti-drain back valves are more flexible and durable than those manufactured by K&N. Alternatively, the K&N oil filter surpasses nitrile rubber in preventing oil from flowing back into the filter.

Flow Rate

One of the most important aspects to consider when choosing an oil filter is flow rate. A filter’s flow rate indicates how much oil can pass through the filter over some time. The higher the flow rate, the more oil that can be filtered.

K&N oil filters have a high flow rate of 9-16 gallons per minute, making them ideal for use with high performance engines. Wix oil filters have a flow rate of 6-9 gallons per minute.


K&N will typically cost you a little more than Wix, but not by much. That said, K&N does offer a wide range of filters at different price points, so you may be able to find one that fits your budget a bit better.

Wix makes it easy to find the right filter for your car with their “Finder” tool on their website, and they also have a handy chart that shows you which of their filters are compatible with which car models. As for price, Wix filters tend to be a few dollars cheaper than K&N filters.


Both K&N and Wix make high-quality oil filters that will do a great job of protecting your engine. However, K&N does have a bit of an edge when it comes to quality control.

K&N’s manufacturing process is ISO 9001:2008 certified, which means that their filters meet high standards for quality and performance. In addition, all of K&N’s filters are tested to ensure that they meet or exceed OEM specifications.

Wix’s manufacturing process is also ISO 9001:2008 certified, but they don’t seem to test their filters as rigorously as K&N does. That said, Wix does offer a 100% satisfaction guarantee on all of their products.


Efficiency is important when it comes to oil filters. A good oil filter will remove contaminants from your engine oil, keeping it clean and extending the life of your engine. K&N and Wix are two brands that make high-quality oil filters. So, which is better?

K&N oil filters are known for their high efficiency. They have a pleated design that allows them to trap more contaminants than other types of oil filters. They also have a low restriction design that helps improve engine performance.

Wix oil filters are also very efficient. They use synthetic media that traps contaminants better than other types of media. They also have a higher capacity than most other brands, meaning they can go longer between changes.

So, which is better?

If you’re looking for an oil filter with a longer lifespan, then go with K&N. If you’re looking for an oil filter with a higher flow rate, then go with K&N. If you’re looking for a more efficient oil filter, then go with K&N.

So, overall, we think that K&N oil filters are better than Wix oil filters. However, it really depends on your specific needs and preferences.


Both K&N and Wix make high-quality oil filters that will do a great job of protecting your engine. However, K&N oil filters are the better choice if you are looking for quality and performance.

They cost more, but they are worth the price because they last longer and provide better protection for your engine.

Wix oil filters are a good choice if you are on a budget. However, their lower quality means that they won’t last as long or provide as much benefits as K&N oil filters.
