AFE PRO Dry S Filter

There are several types of cold air intakes on the market today.  Today we aren't going to talk about the standard oiled type air filter.  The media we will talk about is called the: A F E PRO Dry S Filter

Many people have complained about messing up their mass air flow or MAF sensor due to an oiled filter.  They never had any troubles when they first start using the kit.  It always seems like it is later on that they begin to have trouble. The reason for this is one of a couple of things. All of the reasons come back to not properly cleaning and re-oiling their filters. When cleaning an oiled filter you have to let it fully dry after washing it. This takes time. Most people are impatient and don't want to wait for it to dry before re-oiling the filter and as a result end up messing up their MAF sensor. The other main reason is over oiling. Many kits today come with measuring tools to measure the correct amount of oil. If you over oil, the filter doesn't work as it is designed to do.  

The Dry flow filters bypass getting oil on the MAF, because they don't use oil. To clean a dry flow filter, usually you'll tap the filter on the ground to get the big debris out and then wash it. You have to wait for it to dry fully before using it. But you don't have to worry about oiling it. You just let it sit out and dry and then drop it back into the intake system. The dry flow filters filter almost as well as the oiled filters and bypass the worries of over oiling or not oiling properly. The AEM brand and A F E Brand intakes are the only ones that have dry flow filters, but I'm sure many will follow. AEM does dry flow filters exclusively. A F E offers a 5 layer oiled filter, a 7 layer oiled filter and a A F E Pro Dry S filter.
