Ok, I'm confused. Today I ordered 6-Autolite double platinum spark plugs for my '06 Rubicon. According to the auto parts store, and the Autolite website, the '06 Rubi takes part #APP5224, and that is what I ordered. They are due in tomorrow.
Upon searching the web tonight, I found that according to partsamerica.com and autolite.com the '05 and earlier 6cyl - 4.0L Wranglers take part #APP985.
#APP985 or # APP5224. Both are Autolite Double Platinum. What is the difference?
My hood sticker says use NKG ZFR5N, and that is listed as the correct plug for '06, '05, and earlier 6cyl - 4L Wranglers. Why would the Autolite Double Platinum Plugs be different for the '06?
