Power vs. Cooling - what would you do?

  1. Power all the way and forever

    Installed this uses the drivers side hood exhaust vent for air as well as the headlight opening. they state it is a 38.5 HP increase. I am wondering about engine cooling since one of the vents is blocked from cooling the engine bay. Anybody got this installed? If so, notice any cooling temp increase? How was the power gain? Worth the $280? k&n.jpg

    You will be lucky if you gained 2hp....might have even lost power based on some other observations by a few members here....those K&N (and other companys) claims of HP increases have been proven over and over to be BS..

    It wouldn't be using the side vent in the hood for air...that vent is used for hot air to escape, not cold air to enter. If you're planning on driving or leaving the car in the rain, you will want either a dry charger to put over the filter, or a cover on top of it. Any intake claiming gains of 30+ horsepower simply by bolting it on are sadly mistaken. Intakes, WITHOUT A TUNE, are simply for looks and for more supercharger whine. If you're running pulley upgrades and tuning, then an intake can be very beneficial as long as your tuner knows what they are doing. There are numerous threads on it that will provide hours of reading LOL.

    When I had upgrades done on my car, the tuner said it made less HP on the dyno than the stock airbox did, so mine is sitting in the storage unit now...

    For reference those 2 rear canted hood vents are there primarily to reduce front end lift at very high speed, not to remove heat.

    I put the k&n on mine....don't know if there's any gain or not....feels more responsive....maybe in my mind, but I love the sound....I did change the filter to the k&n oil less filter....cause of all the controversy about oiled filters & maf sensors.....didn't want to take a chance....also put on a dry charger.....I don't drive this car in the rain anyway....not my DD...

    After seeing the thermal pictures of the hood vent, I don't see how an open air element is good for the cat.

    someone on here had dynoed results & there was a gain....search it out......looks nicer, better sound, & easier access to filter....if your not driving in the rain......which I dont......I like it.....to each their own......

    Dynos are great for use as a tuning tool but not for measuring output. The track is the best meter of performance gains and the members on here that are experienced at the track reported no gains with a CAI...some even lost MPH.......but yes you get a better sound and easier filter access...looks depend on the beholder..

    That must be why they are called air extractors.

    I don't understand how you can loose hp by giving it a little more air flow....can only help......

    Many factors, not just increased airflow, affect it. You want the flow to be smooth, the air to be cool and dense, and the correct amount of fuel mixed with it. This is why the intakes show more power gains with tuning, rather than just slapping it on.
