Make sure you use genuine NGK plugs, otherwise you will have problems.
Cons: will have problems
I used the gimmicky Bosch Platinum 4+ plugs which solved that problem (no more CELs) but sometimes idle is still a bit rough.
Pros: solved CEL problem
Cons: idle still a bit rough
Vehicle:
Ford
I run Champion plugs in my Harleys. I have never had an issue with them and when I did try others, I never noticed any improvement over the Champions.
Pros: no issues
Cons: no improvement over Champions
Denso or NGK. Buy them from a real vendor not eBay or Amazon or anything like that
Replace with OEM - Denso. And yeah, get them from rock auto. Anywhere else is way too expensive and eBay is most likely counterfeit garbage.
Cons: expensive elsewhere
2004 1.4 Jazz. 225.000 kms approximately. It is OK but the idling is poor (having done a valve clearance and changed spark plugs and coils). Meh…..it is still holding so I’m hoping for 100.000 kms more
Pros: still holding
Cons: idling is poor
Vehicle:
Honda Jazz
Mileage: 225000 km
Out with the old and in with the ngk 94833
Don't use AutoZone crap
Cons: AutoZone crap
Vehicle:
Audi A3
Part number: 94833
These things literally blast out spark plugs ????. Lots of other tricky issues too. I'm know I'm very biased towards GM but I wouldn't mess with this generation at all for a Ford lol.
Cons: spark plugs blast out, tricky issues
Vehicle:
Ford
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.
Pros: increased gas mileage
Cons: truck started backfiring
Vehicle:
Ford
Mileage: 100000 km
