Best Spark plug for Honda Fit

On my Honda Fit that would be an excellent price because you have to take off a cowl to get to the plugs.

Only things other than oil changes and brakes have been spark plugs at 100k and 200k, fuel injector at 120k, transmission fluid at 200k, and ac compressor clutch at 230k. 2012 automatic

Should have used NGK Laser Iridium plugs and Hitachi coils.

NGK Laser Iridiums will last longer, but those aren't bad per se.

I just got whatever the NGK equivalent was of the Denso IK22. One step colder works great on my car considering it gets thrashed. Comes up to temp extremely fast which helps fuel economy.

NGK OEM equivalents or Denso IK22 for a slight bump in performance.

I've always used NGK plugs on my Hondas. My 2nd generation Fit I installed NGK Laser Iridium.

I went with the NGK rutheniums as they're also rated for 100k and were slightly cheaper on Rock Auto than the iridiums. Supposedly they maintain fuel efficiency longer over their life than iridiums

My 2010 came with denso, replaced them with ngk at 100k, then at 200k replaced them with denso…not sure if it made a difference

struggling to home diagnose what’s wrong with my 2015 Honda Fit (around 160k miles). Worked fine 2 days ago when I last used it, Went to turn it on this morning and it sputtered then stopped. Red oil light came on, red battery light, and orange power steering light showed on dash. Brake pedal locked up. We changed the oil, checked battery life (at 70%), replaced spark plugs and alternator coils (needed new ones anyways), and it’s STILL not starting.
