Any one know the plug gap for the spark plugs?

Thanks

0.028 - 0.031 is recommended for turbo plugs. .028 is what I gapped mine at.

NGK iridium plugs come pre-gapped and highly recommended.

Adding another question to this post:

Does anybody know the correct index position for the plugs or is 6 o' clock satisfactory?

6 should be fine as it's pointed towards the intake valves, but in all reality, it doesn't matter for these cars. Just torque them to spec and call it a day.

Anyone tried those plasma plugs yet? All I hear is poor reliability and failure after just a few 100 miles.

 

[GaijinPDX]

Now there's some snake oil for you. Basically what they say is because their spark plug ignites earlier, it turns your fuel air mixture into a plasma field. Stick with a highly regarded brand like NGK.

 

[Tuns]

OEM spark plugs are cheap. Stay stock.

Would you recommend the colder one though? rate 7 instead of 6 for the NGK in the 2013 turbo?

Unless your engine is pinging, there is no reason to go to colder plugs. Plug temperature is how much heat the plug retains. Warmer plugs retain heat while colder plugs send combustion heat into the coolant quicker. Heat on a plug is a good thing. It burns away the deposits on the tip so it doesn't foul. You actually want to run the hottest plug that doesn't cause pre-ignition. The commonly believed advice is to go one step colder for every increase of 75-100 hp. Is your engine making 75-100 hp more than stock? If not, then there is no reason to go to a colder plug.

That's what I did, I'm staying on stock. I'm still interested what Hyundai did to this same engine to have the 2015 and up versions using a colder plug.

I have just installed my second set of Denso Iridium plugs on my 2016 Veloster turbo. Pre-gapped .07mm or .32... Work perfectly fine. Takes 10 mins to change. Good luck

.028 is the correct gap for turbo .

 

[andy305mia]

.028 is the correct gap for turbo .

been running .32 for 50k miles not a single misfire or issue

 

[SVTfocusO3]

0.032"

Its off by about 100μm, car don't know the difference.

 

[RPW00Mirage]

That’s cool if it works I’m just saying .028 is optimal and the gap can widen as it degrades.

 

[SVTfocusO3]

Yeah, ill gap mine to spec. Im at only 19k as of now.
