Spark plug NGK or Autolite

NGK Spark plug

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
Part number: 4905S

Autolite Spark plug

I've been running autolite in pretty much every domestic that comes through my shop for years since they’re usually the workhorse for Ford and GM tunes. Also, I haven’t seen any dip in the plug quality lately so that's a good sign. The iridiums are still pulling clean gaps right out of the box.

Pros: clean gaps, good quality
Vehicle: Ford

NGK Spark plug

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
