Because by hand holding every person that creates a thread like "what is the best intake!" or "how do i put gas in my car"or "OMGWTFBBQ does anyone make an upgraded heat exchanger" threads which have been answered 1 billion times it only encourages for more and more of these threads to be created which junks up the forum and frustrates people and discourages people from creating USEFUL threads.


the better you cool a FI car the more power you make

a upgraded HE is not going to help you much
a upgraded and expensive IC will help a little (it is upgraded thats the KEY word) but not worth the $
a chemical intercooler aka ALCOHOL INJECTION will do everything you want for about $200 and will let you increase timng for great power gains

If the little guy is still confused, alcohol injection is good and is cheap and will drop IAT's significantly. The EXPENSIVE mods such as IC and HE upgrades are not worth the $ for the small gains you get.

I hope this helped the little guy!
