any with one of these, what is the inner diamter? how close to the stock piping is it? i need to buy a carb legal intake...... but i think this will be too small for my turbo's needs......

thanks in advance...

 

I have SPT. it works fine

i really dont wanna go out and measure but from what i remember it is just a tiny bit bigger than the stock. the hose coupler that connects the 2 is just a tiny bit bigger and the intake side than the other.

 

well i was asking size, because i usually run a larger turbo ( 20g ) and i need a 3" maf housing.... i think the spt is too small....

 

i will go measure it in a bit and i will get back to you

 

yeah i just measured it and it was 2 3/8 I.D.

 

I hope you have a turbo heat sheild like the SPT turbo heat
sheild or your CAI will be sucking in hot air instead of cold.
Have you looked at the Cobb Tuning intakes?

 

i got the heatr shield you can see in the pic. also after install and batt disconnect i had it ran and a/f is all good.

 

Can you remember off the top of your head what the
A/F ratio was?
Did you actually notest a difference in performance?
Better throttle response or anything?

 

I think it was 14.5-14.6:1 somewhere in there and as far as performance i did notice quicker spool up, well a little less spool lag anyway.

there is alot of wooshing and swooshing though. saved money on a BOV. sometimes you can hear outside the car but the sound is mostly for my enjoyment. it was distracting at first but nowadays i dont even hear it unless someone points it out.

i did combo it with a SPT exhaust and i noticed smoother spool up easier shifting and smoother accel. people will go one way or the other one short ram. the have a thread called THE GREAT INTAKE DEBATE or something . From personally having it i like it and i recommend to anyone. Especially if you worried about staying on dealership warranty.

and if that didnt answer your question Just for kicks after driving it for a bit with the SPT parts i thorugh the stock intake on with and without the stock exhaust and noticed more lag and less fluid accel with the stockers stuff on. i hope this helps

 

That definitely answers my question thanks Irish.
The SPT intake is the only intake I have seen that holds a
decent A/F ratio without tuning.
I have a warranty with Subaru and I will considering getting one
I appreciate your insight.

 

are u sure about that?! thats crazy lean bro...

 

from my research, only 3 intakes are cool with the car(sti)
aem
spt
and k&n intake sri which is what i got and my car is running fine. just recently dyno'ed it 275awhp @ gst's mustang dyno and mike said my car is running fine and consistant.

got it for 200 w/ shipping on ebay.

 

I had this on my car when I was at 349whp and it did fine with my 18g, this is a great rmi and will work great with you car
