Help K&N !!!!!!!!
hey guys, new to the forum
I just purchased a 05 Lariat SCrew 5.4 I wanted to change the air filter to a K&N (drop in). I bought the filter but when i went to change it the stupid factory filter says you have to replace with a filter with a felt liner because others might adhere to the box. The K&N just has the normal rubber lining, im worried about fit issues and it if will melt to the box. (I figured if this was true K&N would of fixed this.?)
Is this true? or just a motorcraft gimmick.
Anyone have used the k&n, any problems? Thanks guys

You WANT the filter to get dirty, as that's a major part of it's filtering efficiency. You really only need to clean the filter about every 50,000 miles or so.. REALLY!
Unless you go into a really, really dusty situation where dust is literally caked on the outside of the filter is when you would do a quick clean, which is brushing off the excess dust on the outside and giving it a light re-oil.
The other thing most folks do is over oil the thing when they clean it every 10,000 miles, and that's going to effect the MAF when you are giving it 5 times the oil it really needs.....
I've had my K&N drop in for as long as I've owned the truck (9 years now) and it's got almost 150,000 miles on the filter alone. I've only done a full cleaning of it 3 times so far! I've never had a MAF issue, I've never had dust past the filter (I've done my own 'white glove' test), and the truck itself has over 212,000 miles on it...
I can't comment on any claims of increased HP or MPG, but what I can tell you is that when I do a cleaning of the filter, I put the stock one back in for the day or so I'm cleaning the filter, letting it dry and letting the oil soak in a bit, I can tell a difference in how it drives..
Seems to have a bit less throttle response to it and a little less 'oomph' going up hills with the stock filter.. I have this one hill in my neighborhood and I can usually get up it without it downshifting into second.. Put that stock filter in and It'll downshift every time!
Anyway, I know I'll get flamed for this... I do every time I post this... Bottom line is you either like them or you hate them.... Too many variables with the care and maintenance of them to make either statement a true "fact"....
