Just like your life, not every part in an automotive comes in black or white, chief among which is the air intake filter. The Wet or Oiled air filter against the Dry filter debate has been raging on for quite a long time without any clear outcome. There are many who swear by wet filters’ ability to boost their car’s performance, while some are constantly worried of oil spilling on the sensor behind the air filter. Many feel good old dry filters are the best at getting the job done. Whatever it is, we believe it to be more of a subjective choice rather than an objective answer on this. Hence, here are the benefits of both to help you choose the one that best suits your vehicle’s needs.
Oiled/Wet Air Filter
Wet Filters or oiled performance filters as they are known are built from high-flowing cotton and treated with oil. What’s more, choosing high quality wet filters and maintaining them with regular check-up of oil, there is a minimum risk to your engine and intake.
The oil is a form of a trap where air contaminants stick, thus providing an extra layer of protection to keep the air free from dust particles. The filter generally comes with a specific amount of oil which maintains itself.
Another major benefit of using oiled filters is the fact that there is lesser frequency of changing the same compared to dry filters. If you have been running your car long enough on a wet filter, you don’t need to replace it often. All you need to do is clean it and change the oil periodically.
Dry Air Filter
Anyone driving a passenger car knows that a dry air filter consists of a paper or a foam like substance which has excellent filtration properties. Generally factory built, the dry air filter intake tends to form a layer of dust and particles over a period of time if kept unchecked. This hampers the fuel economy of the car greatly. At times, compressed air can be used to blow off the dirt and your filter is good to be used again. Thus, there is little maintenance required here.
If your primary purpose of driving is just commute with little emphasis on performance or racing, the traditional dry filter must be your choice.
Which One to Choose?
If you are into performance or racing and stuff, the wet filter is a must. Although a bit expensive than the dry filter, it does boost your acceleration. On the other hand, if you just need the vehicle for your daily commute, you won’t notice any difference with the oiled filter struck in traffic. At such times, best go for the dry filter. On the other hand, wet filters do allow a fraction of large particles inside, which may affect the fuel economy of your car. So if you are frugal with your car, then go for the traditional dry filter! Pick up a performance air filter for your car here.
