ok, so i remember reading on here about someone making a CAI out of PVC pipe and it looked really good, i am wanting to make one too, but as some of you kno im not very good at using this site soo if someone could bring it back up?? or put it back on here so i can get going on this that would be great.. im sure i could do it, but just want to make sure its done right and no screw ups.. thanks

sweeeet thanks man!!.. he did it with 3in im gonna attempt to make mine with 4in (if possible) so i can have some serious suckage!! kinda like a ramhammer setup! ill let everyone know how it comes out

 

just be sure to get a reducer for the throttle body. i dont think you'd see a difference though. you can only suck as much air through as the smallest diameter in the pipe allows, which is the throttle body reducer. you'd be doing it for all looks. I think 3" would be better.

 

i did it out of 4" pvc, and used rubber connectors to connect them instead of peicing the pvc together, the butt dyno feels like it gained some hi end HP above 4K u can look at it under my pics i think? if not i can give u a link to my build...

 

I first made a PVC intake w/4" pipe and 3to4 inch reducers at the air filter box and the throttle body. That was actually a little quieter than the 3.5" mandrel bent steel pipe I am using now. I do recall AIRRAM's original intakes (no longer available) were 4 inch tubing. You should do what you like to do. I will get no points for my intake, but it is simple and effective.
Extra note for thought: cold air intake is better for more power, warm air intake is better for mpg. Odd, I know. Some light reading from metrompg.com: http://www.metrompg.com/posts/wai-test.htm

 

I haven't read your link yet, but what you say makes perfect sense. The cooler the incoming air, the richer the mix should be, resulting in slight power gains, the warmer the air, the leaner the mix should be, resulting in better fuel economy.

Although unless the temp is of extremes, I don't think it'd be a big enough difference to either be able feel it with the butt dyno or at the pump...

 

This is one reason combined with different fuel makeup that cars see about 10-15% loss in MPG during the winter. I go from 15 summer (80s and up) to 12 winter (as low as -30F)

 

Has anyone tried a CAI on an 06 or newer with the MDS?? Does it have any affect on MDS functioning?

 

No it wont have any effect on mds
