    stock so far
    hi i owned a 97 tacoma that was recalled by toyota. I just bought a used 07 dbl cab LB silver tacoma, I am going to be putting an intake on it, i read about the oiled filters and the dry air filters, and how it could mess up your MAF. my Question is can i use an oiled filter w/STOCK MAF, If i do and mess it up is there an after market MAF that can handle it? Or do I just stick with a dry one?.... I am also going to be installing a throttle body extender, put one in on my old truck and it really helped. thanks for all your help

    I will never use an oiled filter again. It's old technology being used on new vehicles with many electronic sensors and such that can be affected. With options like the AFE ProdryS or the AEM Dryflow (I have/had both), there's simply no reason to use an oiled filter.

    honestly, i wouldnt go with a complete intake.......its really a waste of money, and if you go with a filter like the afe pro dry s, and remove the secondary filter, your mileage will be above that of an intake, since intakes work in the upper rpms anyway. just food for thought. and also, dont go with a throttle body.....they wont do anything for a fuel injected motor, honestly. just trrying to save you some $ and get the best bang for your buck.:)

    I've run the oiled filters for many years in many vehicles and never had any problems with them. I cleaned them regularly (every 6 months). When I cleaned them, I let them dry overnight and was careful not to over-oil them.

    I'm currently running an AFE dry filter and have only owned it for a couple weeks and haven't made a full tank of gas through it yet. So - I don't have any feedback on it yet.

    I thought I'd give this dry-technology a try and see what happens.

    If this didn't exist - I'd still be buying the oiled filters.

    I have run the oiled filters for a long time as well. Until I started doing oil analysis. After I saw what kind of crap is getting into the engine from poor filtering, they ALL went in the garbage.

    Oil analysis? What would that tell you?

    If you don't over-oil the filters, it shouldn't get into your engine. Besides that - if the oil gets into the engine, it'll burn up in combustion. It can't be anymore harmful than any crap in the gasoline we use.

    Oil analysis can tell you everything thats getting into the oil, aluminum, calcium, zinc, whatever is exposed to your engine. Oiled filters generally dont filter efficiently anything smaller than 50 microns. And, yes, dirt gets thru them. I have seen at least 10 intake tracts that had oiled filters on them, and they were DIRTY. On my last Tacoma, when I installed the super charger and saw my intake, I was like :eek:. And my filter was always oiled perfectly and cleaned regularly. Anything larger than 20 microns (from what I was told by a friend who is an engineer for what was once Garret Aviation) will cause wear in an internal combustion engine. When I saw how much dirt was in my intake, I pulled my head and did a full inspection. Now, Im in dirt every day, so I may be an "extreme" case, but since I have stopped useing oiled filters, my oil samples have been much better, with just the "regular" metals in the oil, and everything in the good range. You should get samples done every now and then if you want to keep an eye on what is going on inside your motor.

    I don't have enough time in my schedule to keep my truck clean on the outside let alone time to do tests. I'd take termite inspections on my house as a higher priority than an air filter test (or even an engine oil analysis).

    No offense....

    But again - it can't be any worse than whatever 'stuff' is in the gasoline we run through the engine.

    It doesnt take any time. When changeing the oil, put a little bit in a bottle that they give you, and throw it in the mail. We have a bunch of Heavy equipment, and put lots of miles on our vehicles, so I just throw my oil in with the rest. BUT, to each his own. :)

    LOL! You should know by now you can't win, Chris. :lalala:

    I, too, have done multiple oil samples and found high silicate counts while using K&N that went down after when using better filtering non-oiled filters. I just changed my oil recently but I do have analysis for the change prior to that so I'll be able to tell after my next oil change how well the AFE is working.

    I'm glad to hear that someone has seen the same results as me! Thanks, Wilson. :)

    I don't see why anyone would run an oiled filter instead of dry at this point unless they couldn't find one to buy. I mean, they cost about the same except you have to buy an oil cleaning kit for the oiled ones. So that means there's more work to clean it, and the cleaning kit adds to the cost. When there's ones you can wash, rinse, and put it back in why bother with oiled ones? :laugh:

    It's a matter of choice.

    It's the same reason why YOU (and everyone else here) decided to buy a Toyota instead of ****** something else.

    Who's to say the dry-flo filters (or any filter) is better than the others?

    ummmm.... because a dry filter is cheaper, easier to maintain, and has no chance of f'ing up your maf sensor because there is no oil? I said nothing about filtering. Simply the time and money involved in maintaining them and the fact a dry filter will never f'up your maf sensor. Seems like dry filters are better all the way around. (Guess maybe that's why OEM filters are never oiled? :rolleyes: )

    Most people might look at it that way... but not everyone. Again - it's a choice. Lots of people use K&N's or other oiled filters. They have their own oppinions to use one or the other. As do I.....

    Are all AFE filters cheaper in ALL applications?
    Not everyone has problems with their MAF ....I never did.
    How much time do you really save in cleaning the AFE? I haven't cleaned mine yet, so I can't comment on if it saves time or not.
    OEM filters will never be high performance filters (oiled or dry)- they're too expensive.

    Well, wash, rinse dry, and put back in the AFE. I assume you have to do all of that AND apply oil to a K&N. And you mentioned letting it set for 24 hours. Gee, I don't think I can be without my truck for an entire day. I do these maintenance things between other errands and tasks, or after work. Losing it for 24 hours is hard to do most of the time. That also skews the cleaning time if we're comparing that here. :D

    Also, how much does the cleaning kit for the K&N cost? That was my main point. Dish soap and water I already have at home are all I need for the AFE or other dry filters. Don't need to spend more money on special oil/cleaners for dry filters. That alone makes the maintenance cheaper.
