But the biggest thing is i don't wanna mess with reliability at all.
Any input would be awesome thanks guys. |
You should really take a look at the true CAI. Or any intake
proven to reduce IAT, volant makes an effective one also, but
this one looks completely stock and uses the element that has been proven most effective at filtering while not creating excess resistance. I know that when I tow in the summer in the rockies, I get around a 2 mpg increase. Partly because it helps keep my fan off, and partly because it reduces combustion charge air temperature. It results in a minimum 100 degree, often 200 degree, lower EGT as well, these things I have seen.
So, it is not about what "flows more", it is about temperature control. it has been stated that airbox temperature gets over 220 degrees in the stock settup. Then the problem worstens in the turbo...all means lower oxygen concentration and too rapid combustion, things that hurt the efficiency of the motor.
I agree that an exhaust is also a good idea for egt. I went from 8 mpg stock to 11-12 mpg, by adding the airbox, TD-EOC (airdam), and exhaust. Like 40%. And it's much quieter without that fan all the time.
