    The name cold air intake is kind of a deception. Should be called Air intake performance kit, or as K and N calls it, Fuel Injection Performance Kit (FIPK). And they are all good, but don't really offer too much gains until you start adding other things along with it such as headers, or you're running your engine in the higher RPM range. But they do give the engine a much nicer Brap sound. But I do believe URD (Under Dog Racing) offers a true cold air intake that snakes the cone filter in between the grill and the radiator. Might be something that would interest you. Good luck

    Volant for the 2.7l, so legit. Cone filter hidden in the box, cool air from the grille with the scoop attachment and there is a hidden pipe on the side that goes into the fender.

    Get an AFE pro dry filter and you should be good.

    Where 'bouts did you get that? Looks like a nice setup. Could pass for stock if the top didn't say volant.

    The only thing it's going to do is make noise unless you are tuned for it...

    And like was mentioned above most of then draw warm air from the engine bay, not cool air like the stock air box does

    is there any that will give you a little more power? Or are headers/exhaust the way to go.

    I'm going to partially disagree here... Granted the noise is the most obvious change, the power increase is notable as well to a stock tune. I agree that the right system must be chosen to improve performance. It would be pointless to tune after every mod because that would start to get expensive, unless you can tune it properly yourself. Wait until you've done all your major performance mods before tuning and then once you do you'll unleash some better results. You will feel improvements along the way though.

    Headers are a must. Read what I posted here http://www.tacomaworld.com/forum/4-cylinder/85764-doug-thorley-vs-lc-engineering-6.html#post8018235

    I agree with Capt Fluffy. Cold Air intakes are wasted money. The guys in this video are very careful to try most alternatives and they still only get 1.7% performance increase by hanging the filter outside the engine bay in front of a fan.

    Built for maximum low end torque, tooter II.VII intake manifold spacer, LCE long tube header, Injen long tube intake, 2,900 rpm torque peak.

    From my own experience I'd say that headers are the best bang for the buck mod as long as you don't open up the rest of the exhaust system and lose your low end torque.


    While I don't know about 4-2-1 Doug Thorley headers because there doesn't seem to be any 2.7 specific dyno charts on them, I did run a dyno test with an LCE 4-1 folded long tube header on my engine...


    [​IMG]


    ...and it lowered the torque peak by 650 rpm from 3,800 rpm down to 3,150 rpm. The run with the header is the blue lines.


    [​IMG]


    The red lines are the dyno run with the combination of the header and an intake manifold spacer.

    I run a warm air intake for better gas mileage.

    Only way a CAI does anything is if you get tuned for it. The ECU will compensate for the increased airflow using Fuel Trims to maintain Stoich 14.7 AFR....but they do sound cool lol I bought my truck used and it had a K&N intake and throttle body spacer sounds like a vaccumm cleaner LMAO

    A little extra power tends to be a big waste of money. You wont in any conceivable sense notice 5hp. Your engine makes a fraction of what it can at any given time driving around. A 500hp engine is making around 50hp 99% of the time, making it a 505hp engine, it will still be making 50hp 99% of the time.

    If you figure a lot of 'good' bolt on will net a 10% improvement, a 140hp engine becomes, after several hundred dollars, 141.4hp. Yay.

    I still throw money at my toys, but not because i actually expect a real effect.

    Built for maximum low end torque, tooter II.VII intake manifold spacer, LCE long tube header, Injen long tube intake, 2,900 rpm torque peak.



    The best bone stock 2.7 dyno run I've seen so far is: 119hp 133tq

    I did dyno runs on my 2.7 with only these mods:

    Injen long tube intake
    [​IMG]


    LCE long tube header...
    [​IMG]


    No power steering or air conditioning.
    [​IMG]


    ...and it made: 135hp 158tq

    So the combination of those mods netted gains of 16hp and 25tq.

    Intake: $220
    Header: $473

    ...for a total of $693.

    10% of 140 =14
    So total is 154

    10% is a huge improvement on a small motor.. but I doubt you'd get that high a percentage.

    Edit.. just read Tooter's numbers.. looks like he got close to 14% on HP and 19% on TQ! Very impressive!

    Built for maximum low end torque, tooter II.VII intake manifold spacer, LCE long tube header, Injen long tube intake, 2,900 rpm torque peak.
    And the intake manifold spacer added a couple more of each to make 137hp and 160tq.

    So from 119 hp to 137 hp is 18 hp is 15% increase in horsepower...

    ...and from 133 tq to 160tq is a 20% increase in torque and that higher peak torque is reached 1,100 rpm sooner, at only 2,900 rpm instead of the 3,800 rpm peak on a bone stock engine...

    ...and this is with just the stock ECU, no tuning, and cheap regular 87 octane pump gas, so I'm really pleased with how this particular combination of mods has worked out. :)
