Spark plug OEM FORD or OEM Toyota

Toyota Corolla (2017) gets 30/36 mpg and cost $13K with 80K miles on it. Insurance $100/month for maximum coverage. I have had it since 2019 and have never had any maintenance except spark plugs (once), battery (once) and tires (once), and oil changes. So I have spent maybe $1000 on maintenance in 6 years.

My feels like it’s running brand new with 100k plus miles ????

I bought six OEM spark plugs at the Toyota dealership parts counter and it was $12!

New plugs and a fuel filter are all cheap and easy maintenance items that no ones done.

OEM Toyota plugs will probably last forever but it depends if your gas mileage is like 5 to 10 miles less that's the only way I would change the back plugs.

Spark plugs 100k miles - $25

2013 3.5 hitting 170k miles within a few days. Second owner so not sure how it was maintained during it\u2019s life but I\u2019ve done 10k miles so far, needed a waterpump and sparkplugs but it\u2019s pretty normal wear and tear

I do need to change the spark plugs. I haven't done that in 10+ years and 100,000+ miles. It just started misfiring slightly I believe (haven't checked the code yet), but it runs and drives well still.

ford. had the explorer with the long spark plugs that break. did them once and that truck wasnt around much longer. focus. dual clutch transmission failure.

During a 300 mile trip in 100 degree weather, my car decided to start shaking horrendously, and the check engine light started blinking. Ford Pass notified me of a cylinder misfire. Apparently the spark plug was missing a piece, and there was extensive damage. Metal debris throughout the engine, turbo charger, multiple lines and drains. Everything has to be replaced.. but luckily it’s all covered by the 5yr/60k powertrain warranty. Such a huge failure at 46k miles is disappointing. I love the car but definitely have trust issues now.
