Spark plug NGK or BRISK

yup those are done.

the center electode is worn flat and the gap is way too wide.

just replace them. make sure yu use the specified NGK or Denso Iridium plugs.

Yes, they have a lot of buildup and deposits. Make sure you get that exact spark plug again same brand everything don't put anything other than the NGK that originally came with

Fairly easy to do,ive seen this plugs go past 150k honda tech here.

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.

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.

I do NGK 6510 one step colder. I do 0.025”-0.026” gap. I had a shop do my last set since I didn’t trust myself. He accidentally did 0.022” and I put them in and they’ve been fine. The other set is 0.018” and idk if ima put them in. Gotta change the one step colder NGK’s at around 15-20k miles. I usually change mine when I start seeing high spark retard. I’m BT 93/E40 with aux.

I just got some fakes with the EAC logo on the box and the accurate Japan stamp with the line under the p. I could tell they were fake just by looking at the poorly machined threads, let alone the crooked ground electrode that looks like it is made out of casted tin lol.

I bought 2 sets of NGK Irridium plugs from Amazon sellers that turned out to be counterfeit. The electrodes were completely worn off with 60k miles on them. They are supposed to last 100,000 miles. The cars were misfiring and had spark knock.
