im lookin for things to imrove gas mileage i was originally thinkin about gettin a throttle body spacer but not after reading everything about em. i was talkin to my instructor in auto class and he said addin a cold air intake wouldnt do much for regular drivin cause unless its hooked up to the outside air its just pullin in the hot air from the engine. any other opinions as to whether its worth the $180+

 

not worth it imo. from what i have seen, you will end up pulling in hotter air than stock.

 

If you want a good cold air intake, BUILD ONE. Its not that difficult you can buy all of the intake piping pieces and filters on e-bay and a few other sites. You could run it to a location that actually pulls in cold air and save some money.

if you don't really offroad you could route one down closer the ground. that would let you get some fresh air.

 

watch out for puddles then, you dont wanna hydro-lock your rig.

 

What is the basis for running a CAI ?
Some will say the colder , denser air improves combustion .
If that is so , then why do we Northeners have a more difficult time starting our engines in the winter ?
Why is our MPG lower in the winter (and don't use that "Winter formulated gas" excuse either)
There was/is a "chip" one could buy for older engines (which was only a resistor) one could install which fooled the PCM into thinking it was colder air drawn into the intake.
All this did was make the PCM dump more fuel in the engine , hence richer air fuel mixture.(sometimes more power gain) Gas mileage took a dump.

 

just enjoy your truck like it is... i put a K&N CAI on my ranger and had only a 2 hp gain and 3 trqu. just not worth it.
