Auto Air Gloucester supply a range of aircon compressors that includes both genuine OEM products as well as aftermarket products.

They refer to their aftermarket compressors as “pattern” products, and these are given a -P suffix, to differentiate them from their OEM products.

In the above example, both products fit exactly the same vehicles (various Volvo models), however 14-0075 is a genuine OEM Sanden manufactured unit, while the 14-0075P is an equivalent aftermarket-spec “pattern” product, hence the cheaper price.

What you can be assured of though, is that while many of Auto Air’s ‘pattern’ products may be manufactured in China, they are NOT “cheap Chinese copies” and are built to high quality standards, and as such, Auto Air are that confident of the quality of the products manufactured for them that they offer a 3 year guarantee (against defects and workmanship).
