i have a rcsb 4x4 tundra ,perf. exhaust,,,,,absolutely love the truck,,,i drive it real hard,,,,my goal is to burn off my michelin tires so i can put on some real tires. i pulled my charcoal filter today as i've read so much hype on this forum and noticed ZERO difference. no sound or performance change what soever. don't waste your time

For the most part I drive my CrewMax fairly easy, and if I remember right, I had around 8k miles when I pulled the filter. The results were immediately noticeable. The best way I know to describe the difference is like between wearing a dust mask and not wearing one when your working or jogging. The throttle was crisper and the wife and I both thought the sound was noticeably louder.
Did you disconnect the battery after pulling the filter?
i'm with Dan. i beat the breaks off mine every sat night at our "local drag strip". i noticed a crisp throttle and some noise. be sure to unhook the battery for a few mins.

These sorts of changes need to be quantified. Dragstrip testing and/or chassis dyno. Seat-of-the-pants impressions may not draw the correct conclusions.
I believe its hype as well. My mileage dropped considerably after removing the filter...
I have 16,126 miles on mine since I removed the charcoal filter last July. My average at the time was 16.42. It immediately dropped to 16.2. My overall average to this date is 16.01, which means its still going down.
Some of this can be the winter fuels...but the charcoal filter definitely was NOT hurting me when it was in place. I have yet to see higher average mileage than before I removed it.
HYPE!

I have had mine pulled of for almost a year now and looking back on it I think that I just wanted to believe that it made a difference but I don't think it does.

removing the hc filter form the housng does absolutly nothing for performance. I took mine off and looked at it. It has about 1/4 cup of activated charcoal and the see through pouch that holds it. there is no way that this would net any real world gains. most gains reported are most likely in your head that some how that was the "trick" to shave off .0001 off at the track but it just isn't that easy.

The descriptions of the backyard mechanics who removed the HC emission filter are just too funny. Crisper throttle, more powerful engine noise, increased fuel mileage, faster acceleration, etc. are just a unfounded comments. Go borrow your wife's hair dryer and blow through this restrictive filter and see how much of a restriction it is.
Besides, who drives their Tundra at full throttle around town? Normal driving requires only minimal air at low throttle. Most of the time my engine is running 2000rpm's or less.
If you believe that yanking out the HC emission filter gives you better mileage, then try filling your tires with helium...it might lighten the truck and make you float down the highway giving you 100 mpg.......

Looking back at the mixed results people are getting from this, I think it may be due to the different styles of driving people do whether or not they see any difference. One other possible reason is that some charcoal filters are more densely packed than others, varying the amount of flow restriction. Also, some people have other airflow mods (exhaust, headers, etc) while others have left their truck stock/unmodified, which would interact with the intake airflow characteristics. Back when I had two intakes to experiment with (one with the filter and one without), I went back and forth between the two and noticed a clear difference in throttle response and mpg - at that time I had added a cat back exhaust. I'm still seeing an average of 1 mpg better with my modded airbox with only 3500 miles on the truck. I don't think dyno or 1/4 mile testing will reveal anything significant.
