could changing the air filter significantly help gas milage? i changed my filter and it seems my gas goes so much further.

 

Yes, if it was really plugged up you should notice the engine running better too.

 

if you use a paper filter such as a fram then change it every time you change your oil. if you use a k&n filter then clean it as conditions require. I.E. if you are in a dusty area or if you are in a humid area. then clean an reoil sooner.

 

I personally don't understand why anyone uses paper filters any more. Besides the performance gains in a K&N the price is so low that in a year or less it has paid for itself.

I worke at a napa store and had a customer retun a K&N filter he was not happy with it. I use on im my gasser and love it but he had a trbo diesel and drove on dusty gravel roads alot and he had very! fine dust on the clean side of his intake tube and turbo so if I ever get a turbo diesel I may stay with the napa gold and not the K&N.

 

maybe I should invest in one, my gas milege could use a boost.... really bad.

 

I have a used k&n for cheap cheap! email me if you want it @imdarngood@aol.com

 

does anyone know how much a k&n filter will boost your h/p?

 

Not very much, they claim these high numbers but no one that I know who runs one has noticed a big increase.

 

I seemed to notice some increase but maybe thats because I wanted to feel an increase (perception)

Because they trap a lot smaller particle. A K&N will keep out the birds and gravel but not the fine dust.

 

i have a 93 f-150 i-6 300 and the intake was very restricted.
it came in from the front to a box on the driverside then in to 2 tubes to the manafold. i eliminated the box and split the tubes to accomidate 2 of the K&N cone style filters and OMG you wouldnt believe the diff. more power and better gas mialage. lots more power if you run duckting from the front and aim it into the filters.
try it GOOD LUCK!!!

 

K&N filters allow more airflow by being larger thus more surface area, and also having larger openings in the filter itself, thus allowing more debris into your engine. This is why I won't use one, ever, on anything I own.

If I need more airflow, I either find a larger airbox from a junkyard, or fabricate something.

My soon to be twin-turbo 460 will have two air boxes actually, one for each turbo. They as a pair will flow more air than the factory airbox, and since I have two turbos, two air boxes make sense because its easier to connect up rather than having large airhoses going across the engine compartment.

using two caddy northstar airboxes, BTW, not that it matters.
