Spark plug Bosch or OEM Honda

OEM Honda Spark plug

Got my 2019 Civic 1.5T to 93k miles and sold it this fall. Great car. Probably had some oil dilution because dipstick level would creep up. No CVT problems (drain and fill were done at 45k & 90k). Replaced plugs at 90k as well and they looked good although there was a little oil in cylinder 3. Ran great, no codes, high quality oil changes every 5k.

Pros: Great car, high quality
Cons: oil dilution
Vehicle: Honda Civic
Mileage: 149669 km

Bosch Spark plug

It doesn't look eroded. It looks like the centre electrode tip has fallen off. That shouldn't happen. I usually only use Bosch or NGK plugs. I've never heard of Auto lite...

Pros: reliable

Bosch Spark plug

Changed valve cover/gasket and installed new Bosch plugs and NGK boots.

Car had slightly higher rpms at cold startup but didn\u2019t think anything was wrong. After a few days engine started to misfire. I did some research and it sounded like I should use OEM plugs. I purchased Nissan plugs from the dealer and replaced the Bosch plugs. Misfire went away, but higher rpms at cold start persisted.

Pros: misfire went away
Cons: higher rpms at cold start
Mileage: 90000 km

Yes. However as a long time old car mechanic I learned the hard way some new cars are super picky about what spark plugs you put in them. It kind of caught me by surprise. Parts store gave me Bosch plugs their system matched to my GF's Pilot, and it fell on its face hard about a half hour into the next drive.

Pros: new cars picky about plugs
Cons: Bosch plugs caused issues
Vehicle: Honda Pilot

I have a 21 xlt 4wd 2.7 and I do A LOT of driving for work. Recently crossed 80k miles and it started misfiring like crazy shortly after that and threw a code. Pulled the plugs and they were definitely fouled. I did some reading and saw most people change the plugs out around this interval so I went ahead and did it. EVERY auto part store near me only had 1 or 2 oem plugs and I couldn\u2019t really wait so I went ahead and got BOSCH iridium plugs. Well I\u2019m noticing when I get on it or go to speed up at higher RPMs/gears, I\u2019m getting what feels like stuttering or very minor misfires every now but it\u2019s not throwing any codes.

Cons: stuttering, minor misfires
Mileage: 128747 km

OEM Honda Spark plug

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.

Vehicle: Honda Fit
