Does anyone have pictures, results, or know of a place that sells a 4" speed density intake for the stock turbo? I plan on going speed density and making my engine bay look better, would a 4" intake work adversely on my setup or does anyone have any words of wisdom?

STM makes one, jm fab, ETS...

 

a 4" intake would work just fine, plus you won't need to buy another one if you decide to go bigger... Win win situation. And nearly all shops make one lol...

 

I use the 4" tscomp intake. Just had to find the coupler reducer

 

Pm me and I'll send you some engine bay shots.

 

What would the difference be with the vacuum hose attachment or not by going speed density? tscomp shows those options


Wouldn't you need to be tuned for speed density also?

 

Buy two 45 degree 4" bends from siliconeintakes.com, grab two couplers, and make one. If you still want a vacuum port on it go to home depot or ace and grab a 90 degree hose barb to 1/4 npt and thread it into the pipe wherever you want

 

All you really need is one reducing 45 deg coupler and a 45 deg alum pipe. Get an air filter that fits that pipe and you are golden.

this is my 4" on a FP turbo w/ the above mentioned parts. The coupler in my case is a 4-3.25 45 deg. SIS did not have the 4-3.25 coupler, only 4-3, but I did originally buy my stuff from them. I wound up getting the coupler from ebay.

 

Mine isn't as clean, but also with the TSComptuned 4" Intake on a stock Evo 9 Turbo and speed density.

 

That is a simple but good looking engine bay!

 

^^thank you sir!

 

thank you everyone for your imputs! very helpful thanks guys, definitely going to come up with my own 4" intake. will post results upon completion
