These plugs are supposed to last at least 30k miles, so what the hell? Then i got suspicious - the plugs look fine otherwise, and there's no reason for them to wear that fast unless they're running insanely hot. So I emailed NGK and they confirmed that they were counterfeit! That specific batch number was made in Thailand, but the part says made in the USA. They said Amazon isn't an authorized seller, but they're planning on working with them in the future. They even offered to send me new plugs if I mail them in.

TL;DR: Watch out for counterfeits when buying off Amazon.
Sorry you were cheated. While Amazon hosts the sales they are often NOT the actual seller. Check your invoice and call out the seller so we can steer clear of them. "Amazon" doesn't help much and I seriously doubt, given all they have to lose, would be(deliberately at least)selling counterfeits.
