Hello im still fighting with my gas millage - 14mpg.....
so how about spark plugs, i currently have oem Bosch spark plugs (by owner manual) was replaced little over 20000 miles ago
but in my previous experience with bosch i always had bad results, maybe i have to go with something else???

Stick with the OEM plugs. If the engine isn't misfiring, the plugs aren't the problem.
Have you checked the FPR?
Have you had your codes pulled?
