What's the difference?

[URdone21]

Between a dry and oil filter for the S&B CAI from Moe's? And what would you recommend? Thanks.

A dry filter is thrown away after it is dirty and replaced with a new filter. Oiled filters are not thrown away. You simply clean, and oil them, before putting them back in the air box. It's all your personal preference. I prefer gauze filters that you oil, others prefer the paper filter that are disposable. Paper filter have come a long way and they have just as much flow as a gauze filter.

Didn't know that. So both CAI kits (dry or oiled) for the S&B are $300. If I'm understanding correctly, one of them you have to keep buying filters (the dry option), and the other you have to buy some kind of cleaning kit (the oiled option)?

Can you inform me of the costs for the replacement filters and the cleaning kit so I can compare?

it preference wise for you, if im not mistaken you are able to clean the dry filters from the s&b... and it is easier to clean a dry filter beacause you dont have to oil it. Some people say "too much oil and it can mess your sensor". not too sure if thats true.

You are correct RUdone21. Matt, Moe's, has them listed for $30.00. Im not sure how many times you can clean/oil the filter with one kit. Im sure someone will chime in with the answer. I didn't see a price for the replacement filters.

Just saw that cleaning and oil kit for $30. How much are the replacement filters if I decide to go with the dry filter option? I didn't see replacement filters on Moe's website.

I didn't see the replacement filter either. Im sure Matt will chime in shortly.

I just noticed that Moe's website says the dry filter is "cleanable". Maybe it's not throw away after getting dirty?

I never noticed that until now. That might be the best of both worlds.

What's the best way to get a solid answer on this ASAP? I plan on placing an order tomorrow so that I can get it on or before Friday. Thanks.

Call Moe's first thing in the morning. He will take care of you.

Its all personal preference.

Yes, there are differences. Let me try to explain, hopefully in a understandable manner, without injecting too much opinion into the subject. Of course, these explanations are overly simplified, but hopefully they may help.

Dry filters, in general, use a more restrictive filter media (smaller openings between the fibers) to keep dirt and contamination from getting into the engine. Some people consider this to be safer for the engine as it filters out more contamination, while others feel it can choke the engine somewhat due to it's more restrictive media.

Oiled filters, in general, use a less restrictive filter media (larger openings between the fibers) and add an oiling process to the filter to help catch some of the dirt and contamination from getting through the larger openings (like flypaper for dirt). Some people consider this to be less restrictive and conducive to better airflow, while others feel it leads to more contamination entering the engine.

So now, imagine that you can shrink yourself to say, the size of a few microns and are standing in front of a dry filter and an oiled one. If you looked at a dry filter, you would see that the openings in the dry filter media are smaller than you, so if you try to walk through, you can not. If you looked at the oiled filter, you would see that the openings in the filter media are larger than you, but they are also oiled so that if you touch them while going through, you will stick to them (like fly-paper). However, if you don't touch the fibers while walking through the oiled filter media, you will go through with no trouble.

So in the end, it comes down to a personal preference type of issue. Is the "possible" added airflow of an oiled filter worth the "possibility" of more contamination getting through to your engine? I use quotes because neither possibility (pro or con) is guaranteed.

No problem. Post up with what ever you decide on, or any info about the dry filter.

Oiled vs dry has been a sore subject for a while. Oiled filters flow a little better, but this also means they are more prone to allowing dirt through if they are not oiled properly. Too much oil, and you will gunk up your throttle body and IAT sensor...too little oil, and it will not filter the air as well as it should.

The S&B dry filters are technically disposable, but I have cleaned them out with compressed air. Once dirty, you can shake them out to remove bigger particles and then just hit it with an air hose to get some of the smaller particles out of there. You can usually get about 35-40k miles out of the filter. If you live in a dusty area, then you would need to replace it sooner than that though or go with the reusable oiled filter.

You wont feel a performance difference between the 2, so it really just comes down to the maintenance. The dry filters are $45 if you wanted to replace them.

$45 is fair for such a large filter element, but that's a big hit to the wallet, to replace.
My $.02

 

[BlackedOutHemi]

Depends on how much you drive. If they only have to be replaced every 30-40k miles that's 3-4 years for me. That's not really that big of a hit to the wallet at that point.

 

[URdone21]

Just ordered the S&B CAI w/ the dry filter from Moe's. Will probably get here Thursday or Friday.

 

[BlownGP]

You can clean a dry filter as many times as you want. Just take it off. Hit it good with the hose, let it dry in the sun and blow off the rest with the air hose. Done it over a dozen times with my cars. Never had a problem.

I gave up on crappy oiled K&N type filters years ago.

Got my S&B CAI from Moe's today and finished the install. Just as I thought, moving the AC supply line was the most difficult part of the whole install. I had to do this part because my truck is a 2013. At the end of the install, I can only get 1 of the bolts back on of the two that needed to be loosened. The one directly above the air duct (same place as the factory air duct) is the one I can't get back on. I don't think it will be an issue because its still very solid. Any thoughts?

Also, I noticed there are two holes in the bottom of the air box that are left open at the end of the install. They look like the size of a bolt. Both are on the bottom side of the air box closest to the engine. I didn't skip any steps. Are those by design?
