Spark plugs. Why is it so hard?

As an update I almost had to call 911 last night. I decided to look into some platinum plugs and nearly stroked out. I found plugs as much as 14 bucks. EACH. At that cost it had better be an instant 20 pounds of torque everywhere. I’m still on the fence about it. If they last 5 times longer they are cheaper than conventional plugs. The upfront cost is a real gut punch. I think I need to do some more research.
