K&N Oil Filter Review

Oil Filters are like the kidneys of an engine. Filtering out engine oil ensures the engine has fresh oil to run well. As your engine runs it wears and these wear metals collect in your oil. Your oil color darkening over time is a symptom of wear and tear. The oil filter is meant to slow down and extend the life of fresh oil by filtering out these tiny wear particles from your engine. This also means the oil filter has to keep a steady flow of oil pressure to reach crucial engine components. The K&N Oil Filter claims to be the official filter of Nascar. This means that this company knows a thing or two about oil filter performance. 

Materials make a filter either perform well or horribly. In a filter, you are looking for well-designed parts, sturdy materials, and technology that perform well in different oil temperatures. In this review, we will review this filter’s build quality and filtering performance to ensure the best choice for your investment. 

What you will learn:

Build Quality

The K&N oil filter has a heavy-duty construction with metal end caps, a silicone drain back valve, a release valve, and Synthetic media. Synthetic media is constructed to be a more optimized filtering material for tiny particles 30 microns and above. The metal end caps provide a sturdy build to keep oil pressure consistent. The drain back valve and release valve are designed to keep the engine supplied with oil under different oil pressures and temperatures. 

Flow rate

The K&N Oil filter is made with synthetic media as opposed to paper media shown in the image above. Paper media are good at catching tiny particles but can be more restrictive when it comes to oil flow. A Synthetic media is constructed with a more even structure to the material, which increases the flow rate while still being able to filter out tiny particles.

Particle Catcher

The K&N Oil filter traps 98% of particles at 30 microns. Considering we can only see particles above 40 microns, that’s good. Its filtering media is pleated to allow more surface area to withstand longer oil and filter change intervals. The filter media is supported by a metal barrel core, keeping oil pressure steady while doing a good job of filtering the oil. Although the filter can handle it, it’s better to keep up with changing out synthetic oil filters every 5,000 to 7,000 miles.

Price vs Value

With a 4.7 out of 5-star rating on Amazon and over 5,000 ratings, the K&N Oil Filter seems to satisfy a lot of customers’ needs. It is Priced competitively among the premium competition with a price of $15.94 for a pack of one. Considering the quality of the K&N oil filter, this is good value for the money. Remember K&N oil filter is the official filter for Nascar.

Conclusion

Filtering your engine oil is key for engine longevity. So the type and quality of the engine oil filter used matters. K&N being the official filter of NASCAR knows a thing or two about performance engines and how oils flow through them. As long as the filter matches your car’s owner’s manual recommendations as closely as possible, this would be a good filter not only for everyday drivers but for drivers who push their engines as well.

Hello! My name is Javaughn Barrow, a young car enthusiast who writes all the articles for Karcandy.com. I’ve written over 50 articles about automobiles. With each article, I deepen my understanding and expertise in writing and the automotive world. Ever since childhood, I’ve always had a strong passion for cars. All types shapes and sizes were interesting to me. I’d spend most of my time after school researching cars and the more I found out about them the more exciting it was. In my teens, I created a fan page about corvettes posting content at least ten times a day! Yes, I was crazy about it. The page ended up garnering over 40k followers! After a while, I wanted more than a fan page. I wanted to express my passion differently. I wanted to create more helpful content, higher-quality content. My first car was a 2013 VW CC Sport. Learned very quickly car ownership wasn’t as expected. I spent a lot of time replacing control arms, cam position sensors, brake rotors, brake pads, etc. Walking away with more information than I knew before. As I was growing in my automotive journey I was learning about writing. Starting by writing a detailed outline about 300 words long then I would pay a professional to write a full 1000-word article and learn from them getting familiar with the process of writing. The moment I realized I could use my writing skills to express my passion for cars and help people simultaneously, I started Karcandy.com. I realized with my unique perspective coupled with my hard work discipline and work ethic I can create a space online to help bridge the gap between the complicated and simple in the automotive world. I’m motivated by the challenges and work it will take to create such a space. My work ethic is something I choose to refine and make better each day. I think it’s important to push myself and stay committed to my evolution as a human and this website is only one of the results of that.
