Seren I will have my little mule on the hoist today and get your pictures, As to your question on air flow efficiency power so on, I am a licenced mechanic, I have played with trucks cars since I was 10 years old on the farm, and have now turned my love and passion into my lively hood.
I am not a EXPERT, I have been WRONG (ask my exwife) However I have tried just about everthing you can do to a car, Some things voided warranty the second I did it. Others just increase the potential of what is there.
To the statement that a dirty filter doesn't make a differance on engine efficentcy. Yes I do believe that our advances in computer technology will make a engine run, however you will never convince me because I have done the cfm testing that mileage and engine wear will not be increased. For example take your belt wrap it around your chest as tight as you can and run through a dust storm as fast as you can as hard as you can. Did it kill you? Nope were you able to do it? yep was your body happy with you? nope. You get the point.
Now do the same thing without the belt tight on your chest with a properly filtered resporater and do the same thing. Did you notice a differnce?
A engine is just like the human body, it loves clean air, good nurishment,(quality fuel) and clean blood (oil).
Anyway sorry to drag this on I will try to post the pictures to night, As I find most just like to throw shit at each other for coments made like monkeys in a zoo. So I dont like to comment, If you would like to chat through email, you have my address I will be more than happy to share my life lesson on What not to do
to void warrenty.
BTW congrates on your new truck may you enjoy it as much as I do mine.
