I purchased these spark plugs for a 1994 Geo Tracker. They were shipped quickly to me and were packaged in their original boxes inside a larger box nicely done. The spark plugs were exact fit and made the old tracker run like new again. Shipping on line was easy and glad to have the tracker running good again for hunting season. I had a great experience with car parts with this purchase
