Hi i have a 97 jetta and is wat i did considered cold air intake or wat is it. I took the stock box out and added a high performance filter then i ran an air duct tube from the other side of the filter and ran it down so it sucks the air from the ground. Any answers would be greatly appreciated.
I wouldn't call it a cold air intake. It is more free flowing which is totally a plus, along with the cooler air coming into the airbox. A real cold air intake seals with the hood, and does not allow heated air from the engine to get into the intake! What you did is fine though :)
bypass with cover induction, supplies you chilly air and and comparable effect of ram air too. it relatively works on physique aerodynamics which creates a intense-rigidity cellular at section between the returned fringe of the air scoop and the windshield base. Airflow Over and around the Hood Hump makes turbulence and drag which forces air returned in in direction of the interior music. Rain water is not any project because of the fact it relatively is plenty heavier than air. Vacuum operated gate opens to bypass air filter out to get much extra circulate as we communicate into intake. The extra air you have the extra gasoline you may blend with it equals extra potential. i do no longer preserve chilly air intakes, there have been too many engines ruined with water being sucked into engine inflicting hydro lock.
you won't have the same affect as a true cold air intake, but it could help a little. the point of a cold air intake is that it is scooping up ambient air instead of the extremely hot air that is inside the engine compartment. the theory is that the cooler air is denser giving you more oxygen to burn in any given amount of air that comes in. do they work? maybe. it depends on the car, and much on the maker. they will increase the amount of oxygen available to your car, wether or not your car can take advantage of that extra oxygen depends on the amount of air the car was getting to begin with (it may already be maxed out) and the programming of the computer that controls your mix ratios. on some cars they will actually decrease your feul economy and power as the computer is thrown off. after 6 years of running hi flow filters on cars, i average about a 6% increase in fuel economy. at todays gas price that means i pay for a filter in about 3 months.
