Cold Air Intake System

[WJC]

I have a dodge Durango and looking to put a K&N intake system on. It states this will give you about 17 additional hp and increase torque, also give an additional 2mpg which I could use when towing ! Has anyone used this system ? Any pros or cons thanks!

Without the rest of the parts it IMHO will be totally useless. Think of your motor as nothing more than a large air pump. In and out have to be matched or else you will gain nothing. Besides that I would never put a K&N filter on anything. There have been a lot of tests done and the bottom line is, the stock air filter flows better than any of the aftermarket stuff. And, if you are planning to use the washable K&N stuff plan on cleaning your MAF about 4 times a year.

You can believe the claims if you like, but you won't get 2 mpg better, especially when towing. I have very detailed records on a 2001 F150 Ford with a 5.4L, and a K&N filter got me about 1/2 mile to the gallon, on the road. Nothing in town. Acceleration was improved, and you have know how to clean and re-oil your filter so you don't contaminate the maf sensor as stated in post #2.

I also added added a "cat back" duel exhaust, matched the throttle body to the intake, and a few other tweaks. The K&N, made the only change in mileage. This was running the same 150 mile trip, (75 mile trip one way), every Wednesday, same time of day and traffic, for over 2 years. 50 miles of highway, and 25 miles of mountain road, going from 700 feet above sea level to over 3000 feet above sea level.

i just put one on my hemi and all it does is make it super load when you hit the gas
and looks cool, I would save the money for a camping trip

There's no product out there that can give you more horsepower and at the same time, better fuel mileage. You don't make more horsepower with more air...you need more fuel too.

Dave is right!!!!!!

I talked to my mechanic about up grading my F150. His response was to keep my money and use it to purchase a F250. A half ton is a half ton no matter what you add to increase hp and towing.

I used to use K&N filters on several gassers and knew a number of people that also used them and have never had to clean my MAF sensor. I would think that would indicate over oiling. Now, I am not endorsing the use of any of these type products, just saying.

X2 That is a sign over oiling. I had a K&N on my 2000 F150 for 80000 miles and not once did I ever have to clean my MAF.

Only mod that ever gave me more MPG was a Catback exhaust and it only gave me 1 MPG on the highway. It sounded a lot nicer though.

Correct, plus improper cleaning. People that use compressed air to clean or dry the filter element are increasing their chances of having mass airflow problems as this method loosens the filter fibers which are then drawn into the mass air flow sensor.
