Autolites and Motorcraft are the same thing; autozone has a chart that cross references them.
Think about it this way...pay less for your plugs and change them more often
Also, I haven't done this, but I plan to next time....check out side gapping....http://performanceunlimited.com/documents/plugsidegapping.html
Yeah but the price goes from $1 to around $4.99 a plug. I would save the money and just cut them myself.HISSIN50 said:one can also buy plugs that are side gapped already. i might also index them if going to the trouble to cut them.

Kevin, i hear ya. but if someone fears screwing up the knife edge or lives in an apt, a prefabbed plug might be a viable option.89sleeper said:Yeah but the price goes from $1 to around $4.99 a plug. I would save the money and just cut them myself.

Good point JT. Also it was good to mention them because some people might not even know they are available.HISSIN50 said:Kevin, i hear ya. but if someone fears screwing up the knife edge or lives in an apt, a prefabbed plug might be a viable option.
