Spark plug OEM Toyota or BRISK

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.

I use a Brisk n17yc.

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

Get a Brisk spark plug. Worked for me

Been using the cheaper Brisk brand and never had an issue for 20k miles.

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.

Brisk are fine. You have to check them about every 5,000 miles. And change out sooner than other brands.

Last thing on my agenda is the spark plugs. Got it with 131K and I’m pretty sure the previous owner literally sold it to avoid doing them. I know I should have done them yesterday, but god it looks like a bitch, even with Car Care Nut’s guide. I’m planning on doing the job with the new plenum gaskets, and ignition coils while I’m back there.

I was given an "offer" to have my spark plugs changed for $368!
