Perhaps most of u guys will think "well duhh-who doesn't know that"
I made an interesting discovery. I have an Airaid Synthamax system. Out of pure ignorance the driving factor for my choice was that you can just wash the air filter. I had a Brute Force system on my V-10 Excursion and it saddens me to think of all the missed power and mpg I missed.
I bought A Spectre filter-high flow disposable filter to put on when I needed to wash the regular Synthamax filter--it takes a long time for any washable filter to dry despite what instructions might imply. Usually about 3 days has been my experience. Anyway, I put on the Spectre filter and took off on my 30 mile one way work commute. I was shocked!
The Overland had a noticeable increase in power. It also picked up 2 mpg. At 80 mph on cruise with the interceptor tuner, I am now getting 19.7 mpg from the Hemi.
I smacked myself on the forehead. The oiled filter was letting in a larger amount of air. I never thought to even consider that concept. I just wanted a washable filter. It was one of those "you dumbass!!" moments
Ergo, for those who knew all of this--you probably got a chuckle out of it.
For those who did not, I would suggest this fact as a major consideration in choosing a cold air induction system.
