These filters are a stocking item. Sometimes however our inventory can fall short. If needed, we will order directly from Baldwin and then send them to you. We put a extended shipping time to play it safe. We receive orders in about 7-10 business days. Once received they will be sent to you next business day.
All cross numbers listed will spin on and seal. If you need more exact crossovers such as size or micron ratings message me. The crosses listed are only a guide if specifics don’t matter. Use the pictures shown as a help in determining if this filter is right for you.
We are a Baldwin and Fleetguard Filter distributor that purchases new filters directly from them. We also purchase filter from stores going out of business or old inventory stores want to get rid of. These can be from any brand name that are purchased. Some filters may have OE boxes, seals, or plastic wrap missing. Some may even have slight dings or minor surface rust. I do throw away filters I would not recommend using. If any filter has any rust dings or something missing, I will inform you and show pictures. If I feel the filter will be ok to use, I will list them. If you wish to purchase a case of filters you don’t see listed in our store most likely I can order these filters for you. All Baldwin and Fleetguard filters are sold by the case unless smaller lots are shown. If you don’t need a full case message us and we may be able to sell individual quantities. We all want the best prices of anything we buy. If you see any filters or parts in my store that have a higher price than other stores you see in online, send me a message.
We also have several parts that are new or used from vehicles. Soon we will be a source of many used auto parts. All used parts will be cleaned and if possible tested to insure they work. Stay tuned for more parts to come.
We do purchase new and old inventory and also vehicles that will be sold for parts. If you have a shop and those darn filters are just collecting dust, or cars rotting away in the back message me. Send me a list of filters, parts or cars 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 and vehicles look the more I offer.
Thank You for visiting AYP-Parts.
