Why Choose The K&N Brand?

High flow rates

Among the various K and N oil filter reviews, these designs don't slow down the oil flow rate, as some other companies do. Instead, the engine gets the appropriate amount of oil while remaining protected from contaminants.

Highly efficient filtration

The K and N oil filter is designed to provide plenty of filtration, even on the budget-friendly models. Of course, the premium units offer a higher filtration percentage, often allowing for more prolonged usage. 

Fast & Easy wrench-off® removal

With these products, you won’t need an oil filter wrench any longer. Because these come with a hex nut on the edge, you can use a standard wrench for quick removal. 

Anti-drain back valve

The K&N oil filter comes with a sturdy and reliable anti-drain back valve. With this equipment in place, the oil doesn’t drain out of the filter when the engine is off. This advanced technology prevents a dry start.

Universality

Whether you want a K&N oil filter for a motorcycle or your SUV, you will find a variety of options to choose from. K&N makes oil filters to fit just about every vehicle.

There’s another option if you want a motorcycle oil filter. This K&N high performance oil filter review shows why customers continue to purchase this model over and over again. It’s designed to work well with synthetic oil, but you can choose to use conventional if you prefer. The only difference would be how long you would go before replacement is necessary.

The anti-drain back valve ensures that the oil stays where it is supposed to while the engine is turned off. That’s the maximum protection that your bike or Polaris ATV requires. Yes, you will spend a little more on this filter compared to a budget option. However, the superior oil flow ensures the maximum performance you want and guarantees you get far more than you would with a cheap oil filter.

With 97-99% filtration efficiency, there’s virtually no chance of harmful contaminants destroying your bike engine. For the small amount of money spent, it’s quite the investment considering what a new engine can cost. Keep your ATV, side-by-side, or motorcycle in optimal running condition with a simple maintenance procedure involving this oil filter.

Comparing K&N Vs. Similar Oil Filter Brands

K&N vs. Fram

Some Fram models don’t come with an anti-drain back valve. These are a cheaper option for budget-friendly folks, but don’t provide the adequate protection that most people are looking for. While K&N will often cost more, it does ensure that the engine runs smoothly and efficiently.

K&N vs. Mobil 1

Looking at the K&N oil filter vs. Mobil 1, it's clear that these are both premium options. In some vehicles, the K&N seems to work better, while the opposite is true with other models. It's a trial and error effort to figure out what is better for you for many people.

K&N vs. WIX

 Which oil filter is better Wix or K&N? Wix is a good oil filter, but K&N is meant for racing applications and automotive enthusiasts. Because of this design, there is a larger oil flow with the K&N filters. If performance is critical, you would prefer the K&N filter.

K&N vs. Bosch

Again, Bosch is a great brand as an oil filter, but it cannot compete on a performance level with the K&N models. For more oil flow and superior filtration, K&N is clearly the winner, despite the reputation of Bosch.

K&N vs. AC Delco

ACDelco is an OEM brand to provide a direct replacement on many models. The K&N filters cost about twice as much but provide substantially better performance. Many people choose to upgrade the OEM oil filter with a K&N option instead.

K&N vs. Napa Gold

K&N not only has more pleats than the Napa Gold filters. Additionally, these models come with more drain holes for better performance.
