Spark plug NGK or AC DELCO

I plan on doing the spark plugs soon just picked up NGK Iridium plugs.

I put in NGK Lazer Iridium in mine about 60k ago and they've been fine.

I had to pull champions that were hardly worn. NGK ran a lot better.

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

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.

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.

just did my wife’s Nissan rogue and it needed NGK spark plugs that were around $35 each.

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.

I stopped buying “NGK Iridium” plugs on eBay AND Amazon a while back. They’re nearly all chinesium knockoffs.
