Spark plug Champion or OEM Mazda

I’ve had my cx5 since August of 23. Put 48k on it since owning it, bought used at 44k it’s been a dream come true. cx5 just takes regular maintenance like oil changes spark plugs and brakes..and another plus it’s a very sharp looking vehicle inside an out.

Spark plugs, coolant exchange, transmission drain/fill, brake fluid flush, and air filter replacement, stat.

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.

My RX8 also got pretty piss poor compression numbers. The only time it struggled with a start up was with literally the original 20 years old plugs it came with and I had to do multiple hot starts. It still started and carried on.

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.

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.

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.

But let this be a lesson never use champion plugs again
