Spark plug Champion or BERU

Ive ran Beru ultra copper core for a couple months now and they are one step colder. I honestly dont even check gap on them and my shit runs smooth.

I used champion spark plugs.. no problems here

I use only NGK or Beru spark plugs.

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.

use beru plugs rather than Bosch, a lot of Bosch plugs sold for this application has the wrong heat range which can cause misfires.

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

I swapped out the oem plugs for Beru rs7 plugs when I went APR stage 2 at ~3k miles. The car ran well. Fast forward to the present with over 18k miles and is20 swap, and I noticed a few stumbles at idle. Nothing major but I figured I'd change them since APR recommends 10-15k mile intervals (visually the Beru plugs looked fine).

I quit buying Champions 40 years ago for shitty quality.

Champion is garbage.

Champion aren't a great brand. They may have been at one point, but not any more.
