4" intake for airaid
 
Can I swap my 3" intake tube for a 4"?! And if so, where can I get one?! :)

Thanks sweethearts!

Just make one. I have used Spectre couplers and piping in the past....I usually finish it off with header wrap for insulation and a different look.

to be honest idk how much you would really get out of it without also doing your TB...can anyone else chime in? I had the airaid and the curve would def have to increase so its not really making a straight shot. I have the 4' bwoody but it really isnt much better for my setup than the 3.5" according to the posts I have seen. I need to do my TB too. Have you moved your IAT sensor as far away from the engine as possible? that will help a little too

From my experience the Hemi needs a larger intake tube than 3". I used a 4" on my modded 4.7 with favorable results.

If you have a proper CMR tune moving the IAT sensor does next to nothing, as most tuners will know to desnsensitize or remove the IAT timing retard function.

Greg had asked me what he should do for more power (already tuned his TCM, between his big tires and running 91 his pcm tune is closed to maxed out), and i explained to him that without resorting to doing things that would get in the way of emissions testing, this would be a start.

Coop listen to the man! And good point on the de-sensitizing IAT...didn't know the tuners could do that. Max it out Coop...

Ryan - So with mine I have the 4" and a Toona...would the TB be the next natural mod? I know we have gone back and forth about this, but I read conflicting stuff that leads me to believe it would not do much for my N/A Hemi...talk to me, i want to max mine out too :eek:
