"I have a 2003 Buick G.S., with the 3.8 L., S.C. motor.
Mileage is up from 28.5 to 32.5 with the A.C. on, cruise
set @ 65. I have ordered another set for my 2003 Durango R/T.
I'm currently getting 15 M.P.G @ 65 M.P.H. If I could pick
up another 2 on this one @ cruising speed, I suppose that would be an improvement. I'm trying to get as much M.P.G.
out of it as I can, because I just like the thing to much to
part with it. Great product! K., Bristol, CT" —Karl J from Bristol, CT bought a Pulstar Performance Series Spark Plugs for a 2003 Dodge Durango, 5.9L V8.
