K&N reusable air filters are definitely worth the additional upfront cost, as they are designed to last the life of your vehicle. Installing a K&N high flow air filter is the simplest, most cost-effective and least technical way to increase engine performance. K&N filters are worthwhile, are reusable and come with a 10-year or million-mile warranty. If you've ever been to an auto parts store, you've probably seen air filter boxes that promise more power and more torque than the factory filter.
But being so cheap and easy to install, it's hard to believe that these filters actually produce observable benefits. Well, Jason Fenske of Engineering Explained put these claims to the test, and it turns out, yes, high-performance air filters actually do generate more power. The original air filter is almost never a restriction point. I have been using K&N filters on my cars for 10 years or so.I'm not sure if they're really worth it, but I've never had a problem with MAF.
I would have to disagree with this general statement. In a normal passenger car? Sure, it's probably not worth it. However, once you find the need for a high-performance filter, K&N is an excellent choice.I bought a K&N input years ago for my Subaru, and that same filter is still in use and looks like new when it's clean. CRC Sensorklean will remove oil from the MAF.
A couple of original teams have included it as a first step before replacing an iirc mass airflow sensor. I know Chrysler does it for sure.If you grease the filter too much, then yes, it will damage your MAF sensor and even clog the throttle. A simple solution to that would be simply not to grease the filter too much. How do you know if you're oiling too much? In addition to the videos you can find online and tutorials, the cleaning kit describes how to properly grease the filter.
Find an offer (ebay, amazon) for a visit and try not to pay full price.K&N in itself is decent. But it is almost impossible to clean them properly, the oil CAN affect the MAF and dirt sticks to the oil, which means that the filters can clog more quickly. If it's for a daily driver, I'd say no. If you're trying to modify a project car, there's no reason not to, but I highly recommend Specter on K & N.You'll never get a big boost of energy with a cold air intake, but it doesn't sound bad at all.
It depends on what your goal is. If it's about increasing HP, no, it's not worth the money. If you want to eliminate the need to buy a replacement OEM-style air filter every time you make your adjustments, it will take you a few years to get the most out of it.But if you're looking to increase MPG, an air filter that provides greater airflow to your intake manifold while keeping the air relatively clean and free of debris will give you an increase in MPG. He finds that on the test bench, aftermarket filters do in fact more than the OEM unit, with the highest amount of gains produced by the K&N filter (about four horsepower and five pounds).
Using a K&N Power clean is a better option, you can also buy the refill and service kit that includes cleaner and more specialized K&N air filter oil. It suggests that the increased power could be the result of less filtering, especially in the case of the cheaper CarQuest filter, although because it had no way to test the filtering process, that aspect was not observed.It really is that simple and that's why upgrading an engine's air filter is one of the easiest and most cost-effective modifications an owner can make. Warm air is not as dense in oxygen as cold air and, as you may remember, the air-fuel ratio is very important when it comes to making horses. I change my air filter every 20,000 miles, and at 10 dollars at a time I would have to keep my car for 100,000 miles for the k&n to be worth it.
The high-performance air filter will not only slightly increase your power but also improve your vehicle's fuel economy.One is the original air filter that came with my car after thousands of miles, the second is a brand new OEM filter from Subaru, the third is a low-cost replacement from CarQuest and finally part is a K&N air filter. However, for most drivers out there, installing one of these high-performance air filters may not have crossed their minds or they may have wondered if it was worth spending money on one. An engine does not run on gas alone - it needs air (oxygen) and since fire cannot exist without oxygen present in its environment - both gas and air are equally important components in this process. Air is also a critical factor in internal combustion occurring inside an engine - ensuring adequate airflow can maximize engine power and efficiency.For some people adding a high-performance air filter isn't necessarily something they need but something they want because they are interested in modifying their vehicle.
So if more air produces more power - would removing my filter completely not increase power? Yes - you're right - I would - many do just that.
