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