Spark plug Autolite or Denso
Bought two auto light from autozone to fix a quick misfire. Used it for two years then took it out and saved it. Quick changed two with the auto light I had previously saved. And bought another one at autozone. 2 years later still running good. Gotten lazy to changed them out. But still running good in my 08.
Pros: long-lasting, reliable
Vehicle:
Ford
Denso work quite well
Pros: work quite well
Autolite plugs work fine in my Toyotas.
Pros: work fine
The plugs EQT recommends are compatible. I’ve been running Denso 5749 plugs for over 10k without issue
Pros: compatible, no issues
Mileage: 10000 km
Part number: 5749
i just put the densos in my '17 alltrack with a stage 1 tune and they run noticeably smoother than stock. i gapped them to 0.026" before install. it didn't seem like plugs would be that important for a stage 1 tune so i've been surprised.
Pros: runs noticeably smoother

If it didn't misfire until you put plugs in it I would suspect the plugs are the cause.
Cons: misfire after plugs
Make sure if you purchase spark plugs that it is not Auto Light. They tend to mess your vehicle up more and not work well with Toyotas.
Cons: mess up vehicle, not work well
Don't use AutoLite plugs in this car, they are known to have issues.
Cons: known to have issues
Also, Autolite is extra terrible. I would have done anything else.
Cons: extra terrible
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.
Pros: misfires stopped for a month
Cons: misfires returned, does not run well
