Spark plug Champion or Autolite

Them Autolites are sweet, if they were edible I'd ask for them in my Kung Pow?

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.

Ran Autolite Iridum XP XP3922 plugs in it and had zero issues at about half the price of the NGK plugs, and I had a mild tune.

These are good plugs Autolite my mechanic recommended them to me good spark and seems like my truck is running smoothly and there a good price.

I replaced the spark plug with an Auto Lite spark plug. Engine light went away but still runs rough and misfire on acceleration.

Local mechanic used an Autolite plug, not Honda-recommended NGK. Misfires stopped for a month, then happened twice more. I have since discovered this brand does not run well in a Honda engine.

I changed my plugs to autolite because I had never heard anything bad about them. I replaced them after 3 weeks due to misfires, put another set of autolites in and it ran fine for 2 weeks. Started misfiring again and swapped in a set of NGK's, no problems since.

I would never install Autolite on any car, definitely not the WRX.

Out of all my years replacing spark plugs. The only times I got bad spark plugs that misfired right away is the one time I ordered a fake set thru ebay(my fault for not doing my due diligence) and a set of brand new auto lites from autozone.

I purchased some Autolite XP Iridium spark plugs earlier this month and immediately installed them. Within a mile of driving, the car started shaking violently and the check engine light came on. I immediately turned around and reinstalled the old plugs and the problems went away.
