How hard is it changing the plugs on a 2.0? My car is 3 years old now and the plugs have never been changed. Thinking its probably a good idea to do it soon. What are the best plugs to use for this car?

 

NGK are most oem branded hyundai plugs





2010-2012 2.0 Hyundai Genesis coupe Turbo

Hope this Helps you.

 

I'd also recommend changing your plugs more often than that. Have you kept all the other servicing up to date?

 

It's easy to change them. You need a long extension though.



OEM are Denso and are the best. If you get the NGKs the get the Laser Iridium Part Number 6481as it is comparable to the OEM Denso. Set gap at .032"

 

^ Set gap at .032" ??? I thought HMC recommends gap to be between .39 - .42 I thought most GC owners generally set their gaps at .40

 

That's what works for me. OEM they are around .028. The factory spec will cause blow outs.

 

If you're boosted maybe. I've always gapped mine at 1mm (0.040") with no troubles.

 

Hyundai service def says .39-.42 gap

 

I know what the manual says. They come out from the factory at .028.
