Re: AirAid wet or dry filter type and why?
Oiled type: The "holes" that the air flows through are larger than the dry. The oiled type relies on the static charge of the oil to attract dust/dirt particles to the filter and stay there while the air flows through the large hole.
Pro: more air.
Con: How much oil is on there??? Too little and dirt won't get attracted to the filter and go into your motor. Too much and oil will leak off and fly onto your MAF sensor and severely mess up your MAF and cleaning the MAF may not work and then you'll need a new MAF. Then you get fed up and put your stock airbox and stock paper filter back on.
So when you clean your filter and re-oil it, the question in your head is, "Did I use enough oil? Well better safe than sorry.", and you use too much oil.
So some people may chime in and say "I've been using an oiled filter for 15 years and 250K miles and I never had a problem.". And those who ruined their MAFs stay quiet.
My friends with their K&N's and their 4th gen Camaros and Trans-Ams back in the day ruined their MAFs.
I've used an oiled filter on my turbodiesel VW Rabbit and it doesn't have a MAF so I didn't have to worry about it. But when it came time for a new one I just went with a dry so I wouldn't have to worry about oiling it.
BUT WAIT!!!!!!! Some people might chime in and say they read that some professional laboratory tested Brand X dry filter vs Brand Y oiled filter and that the dry flowed more air and trapped more dirt than the oiled.
So until someone tests the exact part number dry filter vs an exact part number oiled filter we won't truly know.
I have used Airaid synthamax dry filters on both my current 2012 CTSV and my previous Shelby and been very happy with them. It washes with mild soap and dries quickly. They even made a blue one for my current car as it is opulent blue. Good guys and a good product. Enjoy your car no matter what you use.

I've always used the K&N oil type because there wasn't really any other options until a few years ago. I thought I try the washable dry type this time simply because it doesn't require buying the cleaner and re-oiling kit.
For the oil type the best thing to do after washing and drying is to spray the filter a little light and give it 30 min. then take a look at the filter and u will see if there are a few spots need a little more oil and then u just mist those areas after all the wicking has been established from the first spray of oil. That has seemed to work on our '09 with no failed MAF's.
