First...I have no idea WHETHER this block will improve mpg...but I have reasons to believe it MIGHT.
The mod is easy to install and easy to reverse.
IF I do see an mpg gain...I MIGHT..........then........try to explain it.
Or better yet....I will let certain parties explain why it doesn't work after it does...as with the recent cone filter mod I tested.
PLEASE...remain as you are until testing is completed. Thank you....
