    I've been seeing alot of talk about Afe and K&n filters on here. But are they worth it? I don't plan on doing any hardcore off roading, as this is my daily driver, but I will go out shooting, camping, and riding (dirt bike) from time to time. Would this be a good purchase for me, and will I see any improvement in acceleration and fuel efficiency out of my 3.4?

    Not worth it, and it can coat your MAF sensor with a thin layer of oil and dirt, no matter how careful you are.
    Don't.

    Well, not quite. If you use a kn filter and a magnet on your fuel line concurrently, your mileage can double by halved.

    Just stick with a regular one. The oil from K&N filters gets on the MAF sensor. Then you have to clean them. Previous owner put a K&N in mine, and it messed up the MAF sensor. With me not really knowing much about my truck at the time and just wanting to get it to run without the terrible acceleration hesitation so I could get to school the next day, the mechanic cheated me out of $90 for a new one at AutoZone. Now its causing my engine to have issues because its aftermarket. I get Fram air filters. Does the job.

    I did a comparison between an oem filter and a K&N several years ago and found no difference in mpg. Didn't notice any hp gains either.

    I run a aFe dry filter on my truck and I like it. I'm not sure about mpg improvement but they are great filters if you want a cleanable filter. aFe makes the filters for TRD btw

    Eh, see my Build Thread sig link. Too many mods to list.
    aFe Pro Dry doesn't use oil, so it won't do anything to your MAF. Hence the "dry". It's a washable filter for $60.

    If you normally change filters every 6 months at $15 per, then in two years it pays for itself and you're not adding to land fills.

    Also, you don't have to make a special trip to the store to buy a new filter. Wash it in the sink, let it dry overnight, and done.

    The OEM filter is good for 30K not 6 months, but it can last a lot longer, I'm planning on changing my current filter at 60K, it's at 45K now with no drop in mpg.

    It must depend on the car. I had a 2012 sierra v6 and on the forums there a guy dyno tested a K&N drop in and had a gain of 8hp and 8tq. When I put it in, I noticed more throttle response. I accidently squeaked the tires for the first time when I first drove it. Maybe toyota's OEM filters are already performance oriented or something since people on here aren't noticing anything

    My MAF was always dirty.
