Excellent service
Came quickly and as advertised. Great transaction
Already unplugged to the best.
Excellent fire off these spark plugs!
I have to give a rating even though I didn't receive my order.
Very weird - I ordered four new ones and these came back as if they had been installed in another car already. Visible scuffing, ceramic already discolored, heck the cardboard box it came in had oil in it. I'm afraid to install these but if you don't hear back it's because I haven't installed them yet or I was too lazy to update the review to say they work fine.
