Best K&N Filters

K&N high-performance wrench oil filter

K&N high-performance wrench oil filter-Very suitable for engines that require high oil flow

We believe that K&N Powersports is the best oil filter for cars that use synthetic oil. The filter is also suitable for motorcycles and all-terrain vehicles. The high-performance spin-on filter is very suitable for worn-out engines that require good filtration.

Design

The Powersports oil filter is designed to reduce the pressure without hindering the filtration process. Each rotary filter is housed in a heavy metal tank. The filter can be protected from extreme weather (such as freezing weather).

The tank is equipped with a 17mm exposed nut. The nut is located at the end of the filter to simplify installation. Resin is installed inside the filter, which can effectively filter contaminants.

The filter does have a backflow prevention valve to prevent contaminated oil from draining back into the engine when it is closed. However, it does not have the function of the Motorsports blowdown valve.

Performance

The oil filter is dedicated to synthetic oil engines. This manufacturer removes contaminants from engine oil with 99% efficiency. In fact, we have not found a better synthetic oil filter.

Due to the nut, the overall length of the filter is longer. This makes it difficult for most cars to pass through the exhaust system. Installation is easy, but it does require a narrow place.

The nut makes it easier to remove the filter when needed. Otherwise, this filter works as expected. This is especially true for older engines, especially those that run more than 100,000 miles.

Overall

This is a superb oil filter that works like an OEM product. There are indeed no major pros and cons that will affect the purchase. Compared with some OEM products, it is a bit expensive, but the price is worth it.

This filter is very effective in filtering out pollutants and keeping them out of the engine. For engines that rely on synthetic oil, we strongly recommend this method.

Pros

  • High flow of high performance engine
  • Very affordable
  • Designed for easy installation and removal
  • Suitable for all types of oil
  • Good efficiency rating
  • Excellent build quality with safety line function
  • Leak-proof backwater valve
  • Robust housing

Cons

  • The medium has no loops (although this may increase the oil flow
  • May be expensive
  • Nuts may hinder placement in the engine

K&N Filters Reviews

Are K&N oil filters better?

David Knight said,”They are a well known brand have a long history in filtration products . are they better ?, they probably are if you use them for long service intervals . otherwise just change your filter regularly as to recommendation. I am not sure that on technical terms you can tell the difference in performance terms with them fitted on a vehicle too many variables.

The only thing I use as indication is a visual inspection of the constructional details like are the pleats ( folds ) of filter material evenly spaced . If the construction looks good it probably is a quality product. And worth any premium on price.”

Is K&N air filter worth the extra money compared to ordinary air filters?

Jason Lancaster said,”I’ve actually tested this, and it’s pretty clear that a K&N filter (or another brand, like AEM) will give you a very slight improvement in fuel economy.

Most people will also notice a slight improvement in throttle response, and dyno testing may even show a slight increase in horsepower…but the variance is often small.

The trade-offs are:

1. More engine noise, especially at wide open throttle (WOT). That’s not a downside for me, but some people don’t like it.

2. More grit and grime entering your engine, or at least that’s what some people claim. This is difficult to verify, unfortunately, as it’s hard to measure the increase in particulate matter in oil when the particulates are so small (we’re talking microns). I don’t subscribe to this theory, but some do, so take that for what you will.

3. The need to clean your K&N filter every 20-50k miles. This is a biggie, especially if you don’t follow the cleaning directions precisely. If you use too much “oil” or “fluid” in your filter, that fluid can coat your vehicle’s MAF (mass air flow) sensor and potentially destroy it. A MAF sensor often costs $100-$200.

Still, when it comes down to it, I’m not sure a K&N filter is for the casual car owner. It depends on your willingness to work on your vehicle.”

If K&N air filters are so good, why don’t all car and bike manufacturers use it?

Matthew Storm said,” In a word, the reason is COST. Many folks out there will tell you that aftermarket performance products are not worth it since the OEMs build every bit of performance possible from a given drivetrain configuration into a car. The logic is that they know more about the car, have LOTS of well-paid engineers, and expensive equipment. And therefore, the aftermarket folks CAN’T do better when it comes to performance. This may be true. But the whole notion that the OEMs are unbeatable when it comes to performance is based on the false premise that performance is a top priority for them. It’s NOT. COST is generally their top priority. And performance parts like K&N filters just cost LOTS nore than cheap, paper filters. Furthermore, although K&N tries to sell themselves on the fact that their filters are reusable, the truth is that the recharge kit generally costs as much as or more than a cheap disposable filter. And cleaning it is rather time consuming and labor intensive, which is not practical for a typical dealer service department. In the end, an OEM does not deem the gains resulting from a filter like a K&N (which depend on the vehicle in question) to be worth the extra trouble and expense. The same, of course, applies to the rest of the car. It is, for instance, well within Honda’s capability to build a 300HP Civic that still gets good gas mileage. But they don’t make this due to the fact that it costs more to build and the average Civic buyer just wants cheap and economical ‘Point A to Point B’ transportation.”
