Automotive Acronyms and Terms

CarPartKings knows that we all don't speak the automotive language as well as the auto parts manufacturers. Unfortunately, the auto parts manufacturers themselves will use abbreviations for certain vehicle attributes or product features that is second nature to them, but not to you. So we feel the need to provide you with some help where we can. Below you will find a list of common automotive abbreviations that you may come across while searching our catalog. May it help you as it has helped so many before. If you have questions or would like to add to our automotive dictionary, please send us a message at sales@carpartkings.com.
