Do I need the STi y-pipe for the intercooler to install on my 06 WRX?

yes the 06 is too short, but the people that sell them on the forums usually include the y-pipe, just make sure to ask before buying

I bought mine without the y-pipe. You still have to get a longer 90 degree elbow to reach the turbo, and those are about $45. I just bought a whole new y-pipe kit off of Ebay. It's a quality kit with good clamps and hoses. It fit my STI TMIC.

I'll be installing it this week or next, so that will be the true test, but all that's left if connecting it to the turbo. The cast pieces fit very well and come with new gaskets and Grade 8 bolts. There are cheaper kits on Ebay, but when I asked questions I got Engrish responses that didn't make sense. Boombop was a very good seller and answered my questions accurately.

OK, I installed my STI TMIC this weekend. The y-pipe kit worked but it required some trimming of the silicone 90 degree pipe to fit correctly. I had a friend that is a BMW tech. help me and I'm really glad he was there b/c it was a bear to wrestle with.

We had to test fit it 5 times before we got it right. It still pushes against my A/C line pretty hard but we added some insulation around it so it doesn't rub.

I also bought an STI hood scoop and splitter and it lines up perfectly. That install I did on my own and it only took about 30 minutes.

I swear boost comes on faster, but the real reason I did it was b/c I'm going to get the car custom tuned.
