So I have 56k miles on my 2013 si and I was wondering what are the best plugs to change to from the stock ones? Will I get a little better performance and not have to tune my car?

if you're n/a oem plugs are best. i believe the interval to change them is 100k miles. or 160k kms. depending on how bad the plugs are you probably wont feel any performance increase. tuning is not required unless you change your exhaust and intake. the ecu will adjust itself. if you are already tuned and your old plugs are real bad you may want to have the tune looked at.
Agree, no more power. Use NGK or Denso.Nice low mileage!!
really they should be changed whenever you feel the car is running strange or just down on power. You can always pull them out to check the diode and make sure they aren’t cracked or anything out of the ordinary. I changed mine at about 95k miles to an iridium plug and the engine sounded healthier, no increase to power though.
that's what i use too. Think it came with the Densox2 on NGK
Worth noting -- no increase in power BUT, if you don't change the plugs when due your gas mileage will probably suffer at some point.x2 on NGK
Interesting. what was the letter/number on the imid?Maint. Minder told me when to change plugs and I think it was around 120k.

im at 125k still stock oem plugs
They want your $. It’s not time to change them.Mainly the dealership said they recommend I change them.
