Default Spark Plugs

I don't remember who told me to watch for my gas mileage to drop off after I installed my Bosch plugs , But they where right ! Plugs only lasted about 6 months, then mileage dropped down, Then engine recently started to miss !.
Installed new NGK TR55'* this Sunday, Running much better now !!
Wish I'd known about the Bosch plugs before I installed them !
Thanks !

There'* a good handful or two of us that have achieved our all-time best MPG'* with the TR55'*. Great plugs.

This story is repeated over and over with the bosch plugs, including me.
Seems our cars like conventional plugs better.

Glad to see you made the switch to TR55'*. I will be doing the same in about a week, I have AC Delco plugs in now but I want to see if I can gain anything.
