the fact of the matter is the less restrictive the intake the better. the problem with your thought process is that you think cold air is better. please do some googling to your hearts desire and figure out why we are all saying this. we are not just telling you things for fun. we are right, you are wrong.
cold air is more dense and helps make power, but ability to flow will ALWAYS outweigh the 'coolness' of the air considering the difference is MAYBE 15* or so at the absolute most. the timing tables in the PCM only adjust maybe 1* of timing from absolute coldest you can get to super hot temperatures. therefore, just about zero power gain. get your facts straight, jump on board with the rest of us, and learn a little bit before you try and tell people things you know nothing about.
