What are the best kinds of spark plugs I can get for a stock Scion tC?
Thanks

 

Many people are going to say Stock Plugs are best for the tC no matter what.
I have NGK, i will list the model number when i get home. I installed them at an impromptu tune-up at 60,000 miles.

 

Yea I was looking at the "NGK Laser Iridium Spark Plug"

 

Standard-___ spark plugs. Don't waste your money on anything special.

 

i have NGK i changed mine at 50k,why cause i honeslty didnt want to wait until 100k for them to go out,and when i put my new ones in i felt about 10hp gain lmao

 

Nuh-uh! Forreals yo?!

 

Yup the original plugs are the NGK part no 4589, also know as the IFR6T11, and "Laser Iridium Spark Plugs". Some tC's come with NGK's and some come with denso, I'd go with the NGK have always been a better plug in my experience.

edit:
to the OP (original poster) - go with the iridium plugs, best out there, plus it's what is to be used in this engine/ignition system.. just get some NGK 4589's you'll be satisfied.

 

stock spark plugs....
