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

It doesn't look eroded. It looks like the centre electrode tip has fallen off. That shouldn't happen. I usually only use Bosch or NGK plugs. I've never heard of Auto lite...

Pros: reliable

When that started I replaced the spark plugs and coil packs. This was done at 82k miles. There were very small amounts of oil in cylinders 1, 2, and 4. Problems still persisted after replacement of plugs and coils.

Cons: problems still persisted

Vehicle: Volkswagen Golf

Mileage: 131951 km

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
