Spark plug Champion or OEM Subaru

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.

Subaru forester. Mine is a 15. Comfortable, decent gas mileage, able to seat 4 with stuff in back. Kayaks fit on roof. AWD helps in rain and snow. Easy to do basic maintenance, but spark plugs SUCK.

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".

Champion are ok if you change them every 2000 miles, otherwise they tend to loosen up at the terminal and you end up having to retighten them on a rigid mount Harley every 500 miles or so.

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.

RIP doing spark plugs at home and not hating life.

Good luck doing spark plugs

But yeah, switch to another brand and stop using champions.
