Custom any K&N filter for your vehicle?

Question

Rather then by a K&N kit for you vehicle why not just buy any of the Round Tapered(cone filter) and attact it to your own tube?
I'm asking this cause they do not make any kits for my vehicle.

Answer 1

That is a waste of money. Might as well buy one of those Vortex-Tornado-Cyclone-Gizmo that was advertised long ago that inproved gas mileage. Never panned out.

The so cold air filters is supposed to work by placing the filter outside the car and receiving a denser air. As soon start running to the engine it will heat up again making it less dense. The purpose is defeated. Well, the stock Air Box does have an opening to the outside too. Even my Dad's 75 Monte Carlo had a duct for cold air. So is nothing new. New cars has an intake disguised on the grill or has a hole somewhere that leads outside. Now, the biggest benefit of the intake outside is not cold air but ram air. For that you have to run pretty fast to achieve a Ram/Turbo/Supercharger like effect. If you see dragsters they have such thing, but the cowling ad extra drag too, so is a balancing act of use or not use it.

The factory air box has a lot of thought on it. It was designed for all kinds of weather conditions. Has larger filter area and prevents from the elements to get inside the filter and clog it. The K&N is exposed to the elements, therefore will get dirtier that the regular filter. It might look nice to have it and impress the crowd. The Looks Wow effect will go up. HPs... no so up.

I know... those types of filters are shown on the commercials used on racing and that is a control environment. Those cars are not daily drivers eating bugs and running in a storm or a blizzard.

Street cars can benefit from ram air if it's gathered from a high pressure area (base of the windshield area) is actually better than the grill. A normal run of the mill OEM cold air box is best. The fancy chromed-up air tubes inside of the engine compartment re-cycle hot air only and that (air) has less available oxygen than cold outside air. Why not drop in a perfectly fitting K&N or GREEN air filter inside of the standard box. The GREEN brand claim higher air flow but all of these high flow air cleaners are careful not to tell you the particle sizes in microns of actual filtration.
I've been running a K&N for five years and the car now has 130,000 miles on it. The crankcase oil consumtion is zero and is always on the clean side with 3,000 - 4,000 oil changes with either Havoline 5w-30 in the winter and Penn Brad 5W-30 in the summer. A recent compression test for the he*l of it has proven to me that no ring or cylinder wall damage has been done.
I do however wash and re-oil the air cleaner yearly.

You can do that and it will be fine. K&N is a name and you really don't get mutch from the filter other than it looks cool.

Actually a few years back they used to restrict flow and lower horsepower when we placed the vehicles on the Dyno. They have fixed them since then.

There is nothing wrong with that. K&N is a very good filter, I run one on my truck and on both of my motorcycles. K&N is a real high flow air fliter. The more air and gas you can put in a cyclinder the more power.
