    Hers is the 2.7, it's got it. I didn't know it was on the top part of the lid. Has anyone just tried cutting the mesh part out? Drilling it out seems much harder.

    for future reference, I took a pic of mine............ STOCK 2006 TRD offroad 4.0 V6

    [​IMG]

    TRD makes ZERO filters.......... they outsource.
    depending on application and who WON the contract, it could be K&N or AFE.

    the 1st design TRD intake for the 2005+ 4.0 tacomas was made by AFE, which is why they are exactly like the AFE stage 2 Si minus the front port.
    AFE in turn made those filters inhouse.

    the newer (FLAWED) TRD cold air intakes for the 4.0 atleast are made by K&N and should therfore use a K&N filter made inhouse.

    K&N oil is not MAF friendly, but SUPPOSEDLY the afe is easier on them. Its a different formula and the oil should not be used across platforms unless known to be compatable. The upside to AFE, is they offer the 5r, 7r, and the DRY filters.

    sounds familiar, Ill look around

    Just pry yourself away from it and drill it solidly into your head that removing it has no benefit. Much easier and a cleaner outcome.

    Alright, I have a stick 2.7, 2003, I wanted to know if this mod really does give more power, and mpg. I typically get 20-22mpg with my truck now.

    It doesn't, but your 2003 doesn't have one.

    It's gonna take at least two tanks of gas to really tell on your mpg

    It doesn't effect mpg, don't need any tanks.

    What happens when you take the screen out that's in front of the MAF?

    I drove my 4.0 about 4 tankful's without the screen and it did not change the MPG, but the engine was not as smooth at low RPM's. so I reinstalled it and around town drivability improved. So I would saw removing the screen does nothing.

    Good to know, so it does help with air flow to the maf.

    It does nothing positive, but you noted the engine didn't run as smoothly. In some vehicles removing the screen lets turbulent air hit the sensor which makes the fuel mixture bounce around.

    Howdy,
    I read all these posts about removing the carbon filter so I took a look at mine. After about 5 minutes I decided to do it. I used a box cutter and just cut around the perimeter and it was done. Took all of 2 minutes. No mess or cuttings to clean up. The Taco loves it. It still runs smooth and I know it is flowing more air without a messy pattern after it went through that screen. It was easy and of course I celebrated with several cool beverages. Have a goodun!!!!!!!!!!
