Reviews of NGK spark plug

They are 2 hot for the engine , (the orange burns ) try colder plugs like heat range 8 NGK (SILZKR8E8G97080) are heat range 8 . The ones you have are 92422 are heat range 6 they are 2 hot . Same plugs fit my 2013 Veloster turbo fit your car .

Factory plugs were causing the auto transmision to take longer to shift and jerk more suprisingly. I assume because the engine was acting differently than the transmission expected.

Make sure you get NGKs: FA/FB/EJ/Etc. love those the most.

Also you might have bad type of plugs - NGK PFR6T-10G is correct one.

Please use original plugs for the replacements. Just yanked out aftermarket NGK platinums because of a misfire. For some reason, Mazda and aftermarket plugs in my experience always resulted in a misfire.

Yes, all the time. No big deal!

The CX5 should not be a problem. All the posts telling horror stories aren’t answering the question. You don’t need to be ripped-off by a dealer for this task. You must have a Friend or neighbor to help! It’s a 30 min job at the most. Be sure to get the right plugs, NGK is a great brand.

Also I like the NGK sparkplugs more than Bosch.

Had some problems with Bosch plugs once.

I’d personally run NGK, they have always performed better than Bosch in these generation engines. Iridium if possible and just whatever my reputable local parts supplier would get me.

I'll just start with my bias of never using Denso for anything anymore but for plugs I only use NGK laser iridium and always get at least 80k out of them.

I changed the plugs on my 2017 raptor recently with NGK iridium plugs. The punchline is that the truck started backfiring when I pushed it. I ended up putting Motorcraft plugs in and it cleared up.
