Bro ABSOLUTELY do the spark plugs yourself. I bought oem Denso spark plugs from Napa Auto for about $180. Then all you need is a spark plug socket w/ swivel head, 10mm socket, 12mm, a couple extensions, needle nose pliers, dielectric grease, and a pick to make life easier.
I only use NGK or Nippon Denso plugs, for a reason after a career as a technician.
Denso iridium spark plugs
New Denso Platinum spark plugs. Car drives great, no codes, no sputtering or stalling or hesitation.
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.
Spark plugs do actually vary for some reason, I always use whats oem to the car. In my case thats the ngk iridium plugs (same goes for cables).
Fitting a decent set (Denso or NGK) of iridium plugs is also worthwhile.
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.
Put in new plugs which are NGK 2309 at stock gap which was recommended by my tuner. DID NOT CHANGE OR FIX MY PROBLEM.
Those spark plugs don't look like the highest quality parts. Get some from NGK or Bosch. Better made parts that are more suited to modern engines
