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’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.
the cheap, no name one it came with was doing the exact same thing as the new NGK one I put in (and properly gapped) to try and remedy the issue.
I’ve had almost all of them destroy themselves recently.
A few months ago i had a intermittent misfire appear and went to investigate it but when I popped the hood while it was running, the wire on cyl 3 was literally popping and sucking itself in and out with the spark plug core still on. I took the plug out and the ceramic was moving in and out from the threaded bit. So it was gapping and slamming itself together while running.
I changed the one spark plug cause I had a spare ngk, I forgot about changing the rest and now I have a new misfire….. I can now feel the tick from combustion going thru the wires on cyl 1 and 4. So now 2 spark plugs are starting to do the same thing. I will be changing to ngk plugs now and won’t be touching Bosch.
Ngks are fine but be careful with them. I myself ran these and changed them at 10k intervals. I met someone at a car meet who recommended 5k intervals w these n I didn’t understand till my engine was gone. They can foul up and break inside the cylinder. Granted in my case it was my fault but it’s happened a few times w other ppl.
