 stock air cleaner.

Hey Scooter,

When I installed my open element cleaner. I did not see any change in my city
mileage, and a small (too small to verify really) increase in highway miles.
Mine is an Edelbrock 1002. This is a pillow-looking triangular air cleaner
with a reusable Foam element. Not exactly what everyone else on the list is
runnin, but for <$20, it looks good and gives me that open element look and
sound. Edelbrock says it will flow 1000CFM, plenty for my stock truck.

Later, about a month back, I installed a Cat-Back system (Dynomax Super Turbo,
3" in, 2x 2-1/2" out). This noticeably boosted my mileage. Before the Cat-
back, I had never been over 300 miles on a 22 Gallon Tank (19-20 gallon
fillups). The first road trip after the muffler, I went 335 miles and could
have gotten more. In MPG numbers, I went from 13-14 city, 15-16 highway, to
15 city, and 16-17+ highway.
