    I wanted to get a K&N for my truck but i was wondering if there were any disadvantages to having the cold air.

    ^this.


    if you want a CAI it should be in a sealed box such as the TRD or volant.

    If you want increased power, save up a few more dollars and get some doug thorley LT headers

    Pulls in cold air, not the warm air under the hood.

    Your truck already has a cold air intake on it. There are numerous threads debating this issue. The consensus is to just buy a drop in filter for the factory intake system.

    Interesting video but not broad enough. They test a specific car over and over again with different intake setups. All you can draw from that is a CAI won't work for a Skyline. Some vehicles aren't set up nearly as well from the factory. Fortunately, our Tacomas are set up pretty well from the factory so there are only minimal gains to be had with SOME cold air setups.

    Plus The Skyline is turbocharged, ours aren't. In another episode of theirs they did runs with a N/A Daihatsu too, they lost power with pod filters inside the engine bay.

    Yeah they're totally different cars, but hey it was cool :cool:

    I keep reading this, but my Mustang also drew air from inside the fender. I never measured the power outpu, but I do know my mileage increased by minimum 100 km per tank.

    I would not get one if I was you.

    I bought one and put it in my 07 dodge with an electronic throttle control (E.T.C.) and the first winter I went through with it my computer sensed the throttle valve sticking because of the oil that had blown from the filter. It shut off the engine and I lost all power. (Including power steering and I was trying to turn a big lifted truck right when it happened) It wouldn't run right after that. The air inlet system was the same as on our Tacomas and I never put any oil on it. It was just how it left the factory. I was pissed. I spent about $60 on it and had to take remove all the inlet and throttle body components and clean the oil from them in the snow because my truck was lifted and to big to fit in the garage!! Not a good experience!!
    I would highly recommend staying away from them.
    Plus, there is a reason why they breath better, they let more crap through with the air. There was quite a bit of dust mixed with the oil I had to clean up in the throttle body.

    And the K&N filter doesn't filter worth a shit.

    Send a couple of used oil samples to Blackstone, then switch to a K&N and send a couple of samples.
    By the 2nd or 3rd sample, the silicon levels will be high enough for them to express concerns that you should check the seals in your air filter housing.

    I've seen engines with under 50k on them, with the factory crosshatch honing marks still visible, show serious scoring after running a K&N.


    Seriously man... just stick with the stock paper filter.

    That wasn't due to the filter.

    No, it wasn't due the filter, it was the intake. Perhaps it was the location of the filter (at the inlet vs half way down the tubing), maybe it was routed more efficiently...don't know. Just know that I saw significant gains, and then it dropped back down when I put the stock back on before trading it in. My only point was that I keep hearing guys say that our trucks already have essentially cold air intakes, and that in and of itself, based on my experience doesn't negate the benefits of an after-market system. Truthfully, I couldn't tell you the affect on our trucks, just that I don't believe the arguement that an after market is a waste because the stock already draws from the fender is valid.

    As to the other arguements against, most sound plausible.

    I will be putting in a new TRD intake this weekend and pulling out the current K&N 66 series. Tired of sucking in hot air...

    If you or anyone else for that matter has a SGII or Ultragauge make note of the Air Intake Temperature reading before and after switching.

    With the factory air box and cruising on the highway at about 65MPH the "IaF" read out on my SGII is usually just a couple degrees more than the outside temperature.
