Tiny but hold a lot of power
code readings indicated that I was having misfires in 2, 3, 5, 6, 7 after purchasing these spark plugs and installing them my car runs like a dream. It floats! And it's an American made car! 2003 Grand Marquis

Packaging was poor
First time using 1aauto. Don't think I'll be returning though. Products were fine. Price was good. I ordered 3 sets of brake pads and 1 set of 8 spark plugs. When I received the box, All the items were in one box. The box was mangled from the weight of the pads and being tossed around by UPS. All of the spark plugs ended up under the pads, boxes destroyed. 2 of the plugs were cracked, one was completely broken. Porcelain pieces everywhere. Just went down to AutoZone and bought a new set. Not worth the time and trouble of requesting a new set be sent out, etc. Thanks anyways.
