We are a Baldwin and Fleetguard Filter distributor that purchases new filters directly from them.  If you wish to purchase any filters you don’t see listed in our store, it’s possible we have them in stock, if not we can order the filters for you.  We all want the best prices of anything we buy. If you see any new filters in our store that have a higher price than other stores you see online, send me a text.  Filters are also sold locally that could limit availability of filters you see online. 

If there are any filters we need to order or are short on stated inventory, I will text you personally and not from a robot.  Please leave a cell phone as your contact.  Otherwise, you will need to contact me for status.  Contacting me by text is best way.

Filters ordered Monday, Tuesday and Wednesday before 10am will ship out on Thursday.  

Filters ordered Wednesday, Thursday before 10am will ship out on Friday.

If you have a shop and those darn filters are just collecting dust. Send me a list of filters you have and how much you are asking and your location. I will look up part numbers you send to find the wholesale value and send an offer to you. The more presentable the filters are the more I can offer.

Thank You for visiting AYP-Parts.
