pwrliftin Posted September 5, 2011 Posted September 5, 2011 Has anyone used them before? About time to do plugs and wires and I see commercials for them all the time and ads at autozone, but I don't know anyone who uses them. Theyre not outrageously overpriced, just tryin to see if anyone has had any actual luck with them.
JeffN Posted September 5, 2011 Posted September 5, 2011 looks like they would have to be indexed to reap any real benefits.
dasbulliwagen Posted September 5, 2011 Posted September 5, 2011 Not worth the money for our trucks. The best plugs for our motors are OEM coppers. Sometimes the high tech plugs can cause running problems in the 4.0 and 2.5. Working in the dealer Ive seen this happen and OEM plugs take care of the problem.
pwrliftin Posted September 6, 2011 Author Posted September 6, 2011 ok, cause from the commercials they sound great, and theyre only 6$ a piece. figured they were to good to be true :rotf:
JeepcoMJ Posted September 6, 2011 Posted September 6, 2011 they don't ground out properly through the head, causing a weak spark. that's a by-product of having a high nickel content in the casting of our heads. stick to stock.
Rymanrph Posted September 6, 2011 Posted September 6, 2011 I'm running them right now and they seem to be doing ok. I'm not sure they're worth the extra money though.
Jerry Posted September 6, 2011 Posted September 6, 2011 FWIW, Running them in my 302ci land yacht, it runs smooth with no misfires.
Keith Posted September 7, 2011 Posted September 7, 2011 The E3 plug is just another gimmick, spark plugs are best defined by their heat range and electrode material. Standard Champion Copper plugs are well suited for your Jeep but the Champion Double Platinum or Irinium plugs will give you better performance and longer life, Platinum and Irinium are the best electrode materials regardless of brand, they require less voltage and wear much longer, cost is the only downside. Do some shopping on E-bay and you might find some priced way down.
mule13 Posted September 8, 2011 Posted September 8, 2011 i was running the double platinums and read all the stuff about copper being the best for our engines. i went and bought the regular copper plugs and installed them and honestly i couldnt tell a difference between the two.this was almost a year ago i havent looked at the coppers since then so i can't attest to their longevity i had a little missing problem once and changed out my cps and it went away. i'm staying with the coppers from now on, since i couldnt tell any difference.
