Got a Link to one you like?Buy an ultragauge or scangauge 2, watch your iat (intake air temps) stock... Compare to ambient air. I KNOW second gens bone stock pull ambient temps at around 45mph. Then see if u need a "cold" air intake.
Keep the ultragauge or scangauge 2, and use it to monitor many other parameters such as a TRUE water temp gauge, voltage, etc. Also usable to read and clear check engine lights and pending codes.
I have used and been a beta tester with ultraguage MX (does trans temps atleast on second gens) i like it, but theres too many parameters available to watch for me. My ADHD makes it hard enough and i have all your normal gauges, plus boost and afr to keep an eye on, but heres the linkGot a Link to one you like?
