Replace spark plugs
for Christmas this year i got a set of Bosch Platinums to install into to truck cuz the stock are pretty much gone after 7 years of driving. i know the what im trying to do and ive helped do it on other cars/trucks... but im really not positive about how i should replace spark plugs. 1st question... do i need to unplug the battery before doing anything. 2nd question... i was lookin at my engine bay and took notice the very small amount of room that i have to do this... do you guys have any tricks or other ways of getting to your spark plugs? 3rd question... anything else i need to know before getting started? thanks for any help.
