HI GUYS!

I'm a long time reader, 1st time poster. I've been reading the site a lot and I like to thank you guys for making work go by so quickly (band)

Anyways, now thats done, I like to post pics of my custom SRI and I tell you how you can do it yourself. So far I notice a deeper sounding engine, I can hear the turbo spool up quicker and I hear what seems like a turkey sound when I shift to the next gear. I assume thats normal?

Parts - I got them from good ole Canadian Tire (Canada)

1x - Heat Shield Filter (I bought Ractive: SF300 Chrome) $39.99 CAD
1x - 2.5 x 2.5 Elbow 90 Degrees $7.79
1x - Coup Flex 2"x2" $8.79 (I used 2x2, but I suggest you look hard for 2.5x2.5 I couldn't find any)

Grand Total: $56.67 (CAD) + Tax + 1 hr of your time :)

Instructions:
1) Disconnect your battery terminal (the one with the plastic cover)
2) Disconnect the MAF and Air Sensor
3) Unscrew/Remove the Stock Air Box
4) Unscrew/Put aside the coolant container (do not unplug, just put it aside)
5) Drill a hole in the middle on the coup Flex for the Air Sensor (Doesn't have to be big, just enough and push the plastic air sensor in)
6) Now put the COUP FLEX in where the maf pipe ends, you'll need to really stretch that to make fit, it takes a few tries (thats why I suggest you find 2.5x2.5) its the hardest thing you'll do (spin)
7) Now put the Ractive Filter at the end of 90 Degree Pipe and tighten really hard.
8) Put the other end into the COUP FLEX and tighten really hard.

9) Adjust to make it fit :P - Tip put the filter over the hole :)

10) Plug the MAF Sensor and Air Sensor in, plug the battery terminal and go for a spin! :)

11) oh before you do that find a place to screw the coolent reservoir :P

Welcome from a fellow southern Ontario member! Check out toprotege.com as well.
The intake looks good, and great first post, but calling it a SRI is a little misleading.
It looks like you have replaced the stock piping, but the intake still sucks air through the same path that the stock airbox does.
A true SRI would be like the AEM or Injen without the last pipe that leads from MAF into the fender well.
To be an SRI, it would have to come from straight off the turbo to the spot where you have your cone filter.

Hey,

Intake looks good! I bought an AEM intake but will do a conversion similar to your's for the winter.

I agree that the title is little mis-leading, but it does basicly the same thing as an SRI (and you save yourself a few bucks :) ), and its an improvement over the stock air box, its at least sucking air from that little hole unlike the stock air box which is not. I could even get another pipe and make it go down the hole and call it a CAI! :) same crap, its just piping

Next project an Air Duct :P
 
That is kinda how I did mine too except the filter is in the fender as the pipe goes through the whole in the engine bay. I just used the lower intake pipe from my old cars CAI. Works good, was free, and sounds cool

I know what you mean, but on a real SRI, the air would travel directly form the filter, through the MAF, down to the Turbo, not follow the whole path that the stock airbox did.
That's all i mean.
