DO NOT TRY THEM!!!!!!!!! I had them on my 88 renix with 115,000 miles on the odo and they didnt even last 2,000 miles. I was wondering why my xj was running so bad, I checked everything (sensors,wiring,comp test,etc.) because I didnt think It would be the new plugs I put in.Finally, I pulled the plugs and to my suprise I had three bad plugs. One had the ceramic insulator which is around the electrode broken which fell over the electrode, and the other two I guess were arcing out the back of the plugs. So I was only running on 3 cylinders which would explain the rough running :doh:. So I pretty much felt like a POS for buying into those gimmick plugs. STICK WITH CHAMPIONS. I will try to get some pictures on here, as I still have the plugs and plan on sending them back since they have a warranty. We'll see how that goes.
