Yea, just do a search for deck plate mod. Someone here did a really good write up on it with step by step how to and even pics!

Yea you're right. Still drop in air filter should do well enough. Trust me K&N is not worth the $$$ its all hype, and the pretty sound.LOL.

make your own. make an area that enclosed from 4 sides: bottom top left side from engine heat then that back side. pipe into the box, put a filter and leave the front and right side open. enclose the area to the side of the engine bay and all the way to the front with the left side.

Yep. Rpms go higher before the truck shifts which may fell like better throtle response but infact it is not.

The OEM air intake system brings in more "cold air" than most aftermarket CAI's.

Can someone give me the part # that will fit 2010 Tacoma I need a AFE pro dry s air filter. I was toying with the idea of CAI but i just want the AFE. PART #? ANYONE?
Thanks in advance!!

The air that the OEM (the one it came with from the factory, or Original Equipment Manufactured) air intake breathes in is usually from just behind the grille itself, or sometimes from a fenderwell. This "air charge" is actually cold (or ambient temperature air), as hot air will just drop your ignition timing (because of pre-ignition or detonation) as the temperature of the intake air increases, and take all your HP with it.

Let common sense help some on deciding just how good an aftermarket part or system is:
1) Why would the Manufacturer short you on the performance it could have for an extra $100?
2) If you gained MPG with a simple piece of tubing and a "one size fits all" air filter element - wouldn't they do that at the factory that built the vehicle?
3) Who do you think has more money and resources for Research and Development - the company that designed and built the entire vehicle, or the company that made that "cold air intake"?
4) If something you could buy and install yourself would actually add HorsePower and MPG, why would any vehicle manufacturer waste millions designing it the way they did (and lose the edge on the competition)?

I know this is a pretty common argument for those who support oem and oem only, but I dont agree. Manufacturers install pieces like the air filter with longevity and durability of the engine in mind. Something that will filter more particles to keep the intake tract cleaner. I am willing to bet that any mfg will sacrifice HP for durability and longevity. The aftermarket crowd, who is interested in this stuff, will do the opposite.

Now, I'm not saying that a CAI will do anything. In most cases, I agree that it wont. However, a better flowing air filter will do something and its easy to prove with some proper, easy tests.

actually, strictly from a financial perspective they're worth it, not having to ever replace your filter. math is math.

second, they do allow more airflow in comparison to a standard air filter once it (the paper air filter) starts getting dirty - which of course you could replace them more often, which only makes the K&N purchase and even better move.

Why are we respectively argueing haha didn't chris4x4 and another member and ,I think it was gadget already disprove traditional aftermarket CAI (other than the ones gadget sells haha) the reason urds "works" is because the filter is out of the engine bay. And I parenthsied works because I have no experience with it but people do like it

Sorry maybe you misunderstoood, the K&N cold air intake kit is not worth the price, i have nothing against the drop in air filter. I just hate having to oil it and being concerned that i put to much oil on it.

Well then you should note that you are waiting longer before shifts, as in youre letting in rev higher before you shift, and that is why you think theres a hp gain. Dont believe me? try it. Pick a set of rpm's that you would like to shift at, preferably under 2k. Then drive your truck around with the knn kit and make sure you shift at the exact same rpms every time. Then take the kit of and do it again with the oem intake. note the difference in velosity gain, and overall speed on the shift.

I'm not sure if I would say it was worth the money but I do like it and would recommend the TRD Cold Air Intake.

Here's an interesting read....................

The OEM intake it came with is (in most cases) going to be the best - sounds crazy but here's the real deal -

The reasons anyone makes a "cold air intake" are:
1) To sell you something that "looks cool" and makes noise (keywords - sell you something).
2) Because "Fast & Furious" was just such a cool movie and "you gotta be like them, dawg".
3) You'll think your ride is that much better than the next one just like it (they made thousands of em).

Now back to the real deal -

Most "cold air intakes" are misleading to begin with. If the filter is an open element (you can see the filter) and it's under the hood, it is actually a "hot air intake" (in other words - they lie and sell you something). When was the last time you ever felt a cool breeze under the hood of a car/ truck? A true cold air intake has to take in air from an ambient source - aka outside the engine bay. If you want one that bad for the "cool factor", or if your car/ truck doesn't breathe from outside the engine bay, find one that fits that description.

The air that the OEM (the one it came with from the factory, or Original Equipment Manufactured) air intake breathes in is usually from just behind the grille itself, or sometimes from a fenderwell. This "air charge" is actually cold (or ambient temperature air), as hot air will just drop your ignition timing (because of pre-ignition or detonation) as the temperature of the intake air increases, and take all your HP with it.

Let common sense help some on deciding just how good an aftermarket part or system is:

2) If you gained MPG with a simple piece of tubing and a "one size fits all" air filter element - wouldn't they do that at the factory that built the vehicle?
3) Who do you think has more money and resources for Research and Development - the company that designed and built the entire vehicle, or the company that made that "cold air intake"?
4) If something you could buy and install yourself would actually add HorsePower and MPG, why would any vehicle manufacturer waste millions designing it the way they did (and lose the edge on the competition)?

Add to that the water protection that a stock OEM air box is designed to provide. Water intrusion is a HUGE concern to prevent damage, and here's the reason, air compresses and water doesn't. If an engine breathes in water, and tries to compress it, it will break in a big way.

Some "cold air intake" kits have a water intrusion valve that is basically a ping-pong ball in a sleeve - good luck trusting an engine to that. I know where they got the R&D on that design, just open up a wet/ dry shopvac and you'll see the same thing. Amazing how brilliant these things are when you dig.

great post. increased airflow is from reduced filtration = engine wear.
