Do KN air filters work?
On a daily driver they are of little or no benefit, and are not cost effective. They provide no noticeable increase in performance or mpg. In racing applications they do improve performance. They increase air flow in the very upper rpm ranges.
It also depends on what type of K&N air filter you get, if you spend the money on a cold air intake you will get better MPG on the highway and you will get more horsepower. If you get one of their stock replacement air filters it won't be as noticeable but you will be able to keep that for the rest of the cars life and instead of replacing it you can just hose it off.
K&N filters use oil to trap particles, which relative to the size of dust particles is similar to glues. They are also reusable by cleaning them with a hose, allowing them to dry, then reapplying the filter oil. The above posters are correct in that the filters make a negligible difference with typical driving; the change in drag is the square of the change in airflow speed.
And they make you burn through more fuel, especially if you have a stock CPU and it feeds more air through the intake system the CPU needs to balance the fuel to air ratio hence using more fuel to catch the increase of air introduced into the system.
I have a 98ToyotaCamryV6 I want to install a kn racing airfilter I need a plastic pipe that has a square side to install the air sensor as a pipe Where can I find one Thank you?
Dodge dealership replaced KN lifetime filter and said that he replaced 11 engines in his first year 8 of them because of KN air filters is that just BS to sell another filter?
HEPA, or "high efficiency particulate air" filters work by trapping particles that other types of vacuum filters would let back out into the air. These filters are beneficial because they capture dust particles and debris that would slip through other types of filters, meaning that they clean better than others.
A KJ is a unit of work, whereas a KN is a unit of force. Work is force times distance, so the two units are related by the expression 1 KJ = 1 KN*m. So, if you want to know how many KJ are in 1 KN, you need to know the distance your force caused your object to travel. For example, if 1 kN caused something to travel 4 m, then (1*4) = 4…
Electrostatic air filters are typically rectangular in shape and about an inch or a little less thick. The secret to their effectiveness is the polyurethane and polypropylene blends used in the filtering material. The fibers have been formulated so that when air passes by them, they generate strong static charges, catching all of the unwanted things out of the air and filtering it.
absolutely yes i have had much better performance with kn filters in all vehicles i have worked on and own K and N oil impregnated cotton filters are absolutely better for performance and fuel economy, BUT be aware, by their nature (allowing freer air flow) potentially allow more foreign particulates into the combustion chamber. This has the potential to cause damage in a few instances. Manufacturers are no longer allowed to void engine warranties outright…
