Oiled or Dry Filters
It's probably one of the oldest debates out there since the inception of EFI engines (and maybe even older than that), but it's one of the most common questions we get when it comes to cold air intakes and filters: "should I get an oiled or dry?" The answer really depends on what you're going for in regards to your truck and which company you have mind, but in the end, it's actually pretty easy to narrow down the choice.
Lets start off by breaking down the filter options from our friends over at aFe and at Airaid. aFe offers cold air intake kits with both an oiled Pro 5 R filter and Pro Dry S air filter. According to aFe, their Pro 5 R oiled filters provide a slight improvement in airflow over their dry counterparts, but in all honestly, the difference is pretty minimal. Airaid offers intakes and drop-in filters in both their SynthaFlow oiled designs and SynthaMax dry designs. According to Airaid, their SynthaFlow and SynthaMax filters have the exact same flow efficiencies, making the choice between them pretty much a toss-up.
Now, which should you actually choose for your truck? The biggest difference between oiled and dry filters is the amount of effort they take to clean. Dry filters, are naturally easier to to clean out and don't require reoiling, while oiled filters are going to require oil when it comes time to clean. With Airaid's options, it's practically a no-brainer. Without a difference in performance or filtration, why give yourself extra work? Go dry. aFe is kind of different story. While the Pro Dry S filters are easier to clean, the Pro 5 R filters do offer better airflow. Our suggestion is to grab a dry filter if you're in an are with a lot of dust that requires frequent filter changes and an oiled filter for more temperate climates.
