I wanna put it on a 1999 toyota corrola what would be a good one?But i dont know which one and if i can even put one in
My friend has a dyno at his shop and we like to see the difference in peoples cars he/we dyno. Like in this case we have OH so many times looked for power gains with KN filters. We have never seen any proof on the screen that KN filters and many other aftermarket products that claim more power actually work. We have also dynoed with NO air filter and even that didn't add power. MYTH BUSTED! KN filters use an oil that is saturated in a cotton cloth held if form by wire mesh. ALL cars with a mass air flow meter for the last 10 years or so can't use a KN filter without problems down the road. The oil eventually makes it way up to the air flow meter and the oil coats little tiny sensitive sensors. Plus the dirt that is not captured by the filter also coats the sensors. When this happens all sorts of problems can happen, from poor gas mileage to a no run situation. KN filters LIE big time on the HP gains and MPG gains its all BOGUS. KN filters ONLY belong on carburated cars and cars with mechanical mass air flow sensors. Some people say this oil in the MAS problem is related to people putting to much oil on/in the filter ALSO a busted myth. Car companies are always looking to get a better MPH and hp and torque rating if KN filters worked and didn't cause problems ALL cars would have a KN filter or similar filter brands in every new car built.
The factory one. The car factory breaths its air form outside the engine bay. Most called cold air intake get there air from under the hood just behind the radiator Just about the worst place to get cold air from. After market cold air intakes are a complete and total scam. They give you no better fuel mileage or power. All they do is make noise and that makes people think that it made there car faster and more powerful. A aluminum pipe does not flow any better than a plastic pipe. And yes the reusable filters do flow a little better but that only helps and extremely high RPM's. And they only flow better because the let more dirt pass through. So is it really worth getting a minimal amount of increased flow when your engine is now breathing in more dirt. By the way if you completely pull the air intake of a car then you only get maybe 2 or 3 horse power. So how would any filter give you better flow making more power than no filter at all? Just use a good wix paper air filter it will work just fine.
KN air filter, which is a controversial item. Some claim the KN increases air flow without loss of protection; others say it is a waste of money, and at worst, that it lets more dirt into the engine. If the KN does make a difference, it is at the highest rpms when airflow becomes critical.
