I had to pull champions that were hardly worn. NGK ran a lot better.
Pros: NGK ran better
Cons: champions hardly worn
Personally I’m running EQT’s stage 1+ tune and I just went with the recommended plugs (NGK 4905s) for peace of mind. I think it’s worth the extra couple bucks for my sanity
Pros: peace of mind
Vehicle:
Volkswagen Golf
Part number: 4905S
I'm using oem ngk plugs changing every 2nd oil change so around 16,000km

I only use NGK or Nippon Denso plugs, for a reason after a career as a technician.
Pros: reliable, technician recommended
The NGK plugs are like $8ea when you buy 16. Still costs you nearly $800 less than what the dealer cost for that job is. And they last 60-75k miles.
Pros: last 60-75k miles
Cons: pain in the ass
just did my wife’s Nissan rogue and it needed NGK spark plugs that were around $35 each.
Cons: expensive
Vehicle:
Nissan
I stopped buying plugs from eBay and Amazon years ago after getting what I can only assume was a bunk set for my BMW. They looked the part, but caused the engine to run rough.
Pros: looked the part
Cons: engine run rough
Vehicle:
BMW
I stopped buying “NGK Iridium” plugs on eBay AND Amazon a while back. They’re nearly all chinesium knockoffs.
Cons: chinesium knockoffs
