A regional tire store / repair center "recommend" spark plugs on my Sienna at 92K for $850 (intake manifold has to come off to get at 3 of the plugs). I asked them what benefit would there be in replacing spark plugs at 92K considering Toyota sets the spark plug replacement at 120K.
2005 Camry 2.4L just changed original plugs at 130k miles. I go 5k on synthetic oil and don't have to add any between oil changes.
The OEM plugs are iridium and are good for 120k miles, per Toyota. I paid about $16 per from a dealership (which I was happy to do, because its a job I dont want to be doing again in 50k miles).
Use the Toyota OEM iridium tip plugs. They are amazing!
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!
Customer had misfires, bought oem spark plugs and coil pack. Customer came back couple months later, misfire came back. Found that port injector was bad.
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
