Hi guys, I will buy the spark plug for my 2016 GT-S. I saw the OEM number 22401AA870 (NGK 95768 SILKAR8D6), and on this site (4turbo.pl), the alternative spark plug is the one for the 2.0DiT engine (NGK 96024 ILKAR8H6).

I need to know if the two types of spark plug are interchangeable, I think yes because on the site are suggested, but I need your help

Thank you

I don't know who translated this website, but in polish it says "Produkty podobne" which means "Similar products" not "Product alternatives". If I would be unsure, then I'd stick with the OEM one.

It's just Iridium, but it's just 1.6 DiT, so I wouldn't expect much. Especially as the gap is the same - 0.6mm (smaller is better for turbo engines).

Euro spec Levorg 1.6 uses NGK SILKAR8D6.
Ok, so I need to buy the SILKAR8D6, I don't know if the ILKAR8H6 has the same propreties (I found on Amazon for 30 euros the pack of 4) but it seems the same
