Sorry if this is a repost, I can't find anything about it when I searched. I have the water injection that I'll be installing here within a half an hour. It suggests copper spark plugs over double platinum. I guess for the temperature to convert the water into steam?
Anyways Autozone only has platinum plugs and wouldn't sell me anything else because that's what ford recommened. I went to the dealership and they were trying to get me to buy some single platinum (wire plugs?) that were 4.80 a piece.
To get copper ones with a 1.3-1.4mm gap am I going to have to order them or buy some and regap them? How much is a spark plug gapper cost? ANY advice would be appreciated.
It will be installed today either way, but for the fuel economy the coppers are suggested. Thanks.
