I just bought a set of spark plugs and plan to do a plug change for my 98 Taurus SE. From the forum, I learned that the gap should be set to 0.054. However, under the car hood, it states gap to be 0.044 to 0.046. Which number exactly should I use?
Also, the motocraft plugs I bought has preset the gap to be 0.052. Shoud I adjust it and also I'd like to know how?
Thank you. I am waiting for you feedback and will start my job right away.
