We had an issue with one of our important accounts about the price of an air filter of all things. 2014 Dodge Charger. Air filter price installed was $51.00. Our price was $25.48. This is for a premium filter as the economy grade was not in stock anywhere and this client demands a quick turn around. Our pricing on filters is based off a pretty standard matrix and we do not charge labor. One of my techs inadvertently got into the debate and tells me how "down south" (he worked in North Carolina for a stint) they only mark filters up $10 and don't charge labor on filters either. Seems unrealistic to me but nonetheless I still would appreciate actual shop owners input on this subject. Am I too high, too low, or in the ballpark? How do you guys price smalls such as filter, blades, etc.?
