This past wknd I went camping on some very dusty roads. The dust was so bad you had to slow down until the vehicle in front was quite a long ways away. I was a bit worried the filter would let some dust in.

Opened the hood last night and the entire motor was caked. Opened the CAI box and the filter was really dirty. I decided to take it off and make sure it filtered most of the dust. To my surprise there wasn't a single spec of dust in the intake tube.

I was quite impressed, but I am not a fan of re-oiling it etc. AFE pro dry filter showed up at the house. Going with this new one for now to avoid re-oiling and destroying my MAF etc.

Yes, "oiled media" filters appear to be going the way of the buffalo, cassettes and zip disks.. Ron

The oiled filters seems to be pretty good, but now with the oil free filters it leaves it with less maintenance:bigthumb:.

Is that the blue filter everyone is talking about??? I'm thinking of picking one up myself. Can you post pics?
The oil-free media filter is white, AFE P/N 21-90044 ProDry S

On a more general note, Kep, how do you like your CAI? Has it provided you with a noticeable improvement in torque or drivability, etc? Am pondering one but am still undecided.

Thx.

Really like it, motor sounds a little more throaty and seems to have a tad more power. This has been debated many times, but most dynos do show slight power improvement. The cost is a little steep, but these can be found in group buys etc.

You won't believe how big the stock intake is when you take it off. My main concern putting it on was filtering, but doesn't seem to be an issue. Good luck with your choice!

Do you have to replace the dry one or is a lifetime filter the way the oiled ones are?
It's a lifetime filter that doesn't require oiling and can be washed with soap and water or dirt can basically be knocked off of it.

I am also considering the filter wrap for off roading to reduce the filter maintenance:

I only have 30,000kms on my K&N so I think I am good for awhile......atleast another 30K.
That's what I thought until this wknd, the dust was horrible. Only had it on for about 10,000 miles. Think the wraps are a great idea, may try one soon...

I have the TRD CAI unit. I was able to notice a small power increase. I have noticed that small hills have flattened out for me quite a bit. I believe the dyno tests claim 11 HP increase. This did make a difference last month when I pulled a 4800 pound trailer 1200 miles.

Fuel economy- slight improvement but hard to measure this statistically.

It sounds great though. This has turned out to be a really good intake filter setup, at least in my case.

To solve the filter oil / Mass Airflow contamination issue, I've got a spare filter. Clean the old one really well. Let it dry, then oil it and come back a few days later, after it really drains down, put it in a zip lock freezer bag and then box it so its ready to go for next time. I like keeping spare parts such as this.

I will say that the oil stops the dust dead in its tracks on the outside of the filter, where it belongs.

I may have to try the dry filter from AFE though.

What kind of prices are we talking about when done through a group buy? Toyota Parts People is selling them for $310. Can you get them much cheaper through a grp buy?
