Spark plug NGK or BRISK

Very broadly, only use NGK, Denso, Bosch, or Champion.

according to my halfords e- receipt i last used cr8 iridium plugs, no complaints here.

NGK all day, compared to all others they’re just made better, I bought Bosch platinum for a VW and the OE came out were NGK, after 50k they were still visually a better manufactured plug. Example- the plating on the Bosch threads was rougher.

Over the last 16 years with my 8 gas engine VWs and Audis, the OEM or OEM equivalent (Bosch or NGK) at stock gap (unless chipped) have performed better and more consistent than any other I've tried.

The NGK's have been a solid go to for me and my little Pocket Ferrari for every day driving.

NGK run good for me

I’m 90% sure my EGTs came with Bosch plugs, switch to NGK that are 2 steps colder for my tune haven’t had any issues with them for about 25k miles

OE plugs for this engine is NGK Laser Iridium. Hyundai/Kia usually use either Denso or NGK plugs.

I've used Autolite plugs in my stock 2011 for 6 years. I wanted to try NGK's so I recently installed a set of Ruthenium NGK plugs. I haven't noticed any difference between the two brands.

I also just put in a set of NGK BKR7E's and gapped them a little large (.034) seeing as the ones I pulled out were at .043 That did nothing and the issue is still persistent.
