I changed the plugs in my 2004 TJ Rubicon today. The old ones were extremely rusty, cruddy, etc., which made me wonder if they were originals. Anybody know what came as original from the factory? The plugs removed were NGK-R "ZFR5N".
I put the stuff on a black hardtop that had gone grayish last spring and it is glossy black yet today, about one year later. Wipe it on with a rag and buff out with a soft cotton or microfiber towel. It will vastly improve the look of your top.
Sorry. New to forum. I do not see that you PM'd me on the inbox little envelope thing. I would really appreciate a call as I am 68 years young and still not very computer literate.
