long time reader, first time poster. 2004 Dodge Ram, HEMI, 78,000 miles, Black, crew cab, laramie, leather, cooper ltz, diy cai w/ k&n filter.

Just wanted to say thanks for all the great info.
i drive 60 miles one way at 55mph was getting 17mpg with stock air box and k&n flat air filter.

Switched to a 4" crapper tube (pvc) and a 4" k&n filter. now i get 18.5 to 18.8mpg.

did see 19.5 with a light wind at my back and a fresh oil change.

although i did have a 4" spectre air filter from murrays and it did just as good as the k&n.

keep in mind that all numbers are from the over head display. and i have not manualy checked them

thanks for all the info

Oh by the way i pull a trailer here and there. weights about 8k and i am getting 11-12mpg now. was only getting 9-9.5 before.

 

damn, i was thinking of doing this, but I just spent 55$ on an airaid intake tube. may have to play with both and see which feels better.

 

The overhead is known to lie, hand check it and let us know the results.

 

congratulations

 

the overhead is not 100% correct but if you are using it for comparing deals like this it is just fine! and thats a great improvment!

 

Where are the pics?
