Spark plug Champion or OEM Toyota
Went in to find some non R plugs today. He popped the rabbit into the system and said "we've got Champion N11YC, non resistive in stock.
I got champion copper core for my 5.7 hemi which was what the factory had in it. I changed them at 68k and they probably could have gone another 68k they looked virtually new.Ran like a champ and I got them with rebates and at the end of the day they were 1.00 each.
I run Champion plugs in my Harleys. I have never had an issue with them and when I did try others, I never noticed any improvement over the Champions.
The proper champion plug is the "QL77JC4" gapped at .030".
In a pinch I use champions.
Customer had misfires, bought oem spark plugs and coil pack. Customer came back couple months later, misfire came back. Found that port injector was bad.
Post inspection they mentioned that the spark plugs have gone faulty and was firing properly. They installed the new spark plugs.\n\nThe issue here is, I have driven cars for 10-15k without changing spark plugs and this is a new car from showroom which had bad spark plugs, also looks rusted, which was unexpected.
But yeah, switch to another brand and stop using champions.
So Champion sucks, more like Chumpian.
Some of my best vehicle purchases have been trucks with "misfires" or "engine issues" and almost all of those have had goddamn champion plugs in them, or a champion distributor.
