Spark plug Champion or OEM Subaru

I used champion spark plugs.. no problems here

I have a Champion 20 Ton model with the 196cc engine. I have used it for 5 years, splitting about 35-40 cords. The only issue I have had is I had to replace the spark plug once. The engine still works well but just in case I bought a direct replacement Power Fist Chonda engine for $229 CDN.

Champion iridium. Champion makes the Mopar plugs. It's the closest thing to the original plugs without having to spend $30/plug.

Changing my sparkplugs for the first time (32k miles, yes it's early but I got a great deal on the plugs) and found that the stock plug in cylinder 4 actually had a ground electrode defect and was significantly thicker than normal. The car runs stronger than it ever has as this was likely causing extra timing pull.

im at 95k with the original plugs. no issues

I have measured resistance above 5k and determined the plug to be causing a problem. Typical resistance is 1-3 kOhm, sometimes less for a new one.

My service center guys installed Champion plug instead of Bosch on my turbocharged Altroz. Company user manual clearly says to use Bosch in TC. My car's economy has dropped significantly...and I'm just frustrated.

I won't run champion plugs in anything but lawn mowers. That's the only thing I've put them in that didn't get angry about it. Guess everybody's vehicles are different, but personally I don't think they're very good plugs.

Champion spark plugs are rubbish, not sure why they’re even sold.

I quit buying Champions 40 years ago for shitty quality.
