AVO Top-Mount Intercooler (TMIC)
I finally installed the AVO TMIC I bought back in March, and figured I would share a few notes and pictures with ya'll.
I bought the AVO TMIC from Infamous Performance & Tuning. As you'd expect, it was shipped expediently and was packaged very well. I order most of parts from IPT simply because I have learned the most of what I know about my Subaru from msprank's comments on these forums. Additionally, I have never had a bad experience with IPT.
The AVO TMIC is beautiful, and has the fit and finish of what I think anybody would refer to as a "quality piece." I was surprised to find that the cooler appears to have a ceramic-y, glossy coating. I'm not sure what this coating is and I'm not sure if it provides any functional benefits, but I can comment that the coating makes the TMIC look really nice and I suspect the coating will make the TMIC resistant to stains and easy to clean.
Perrin TMIC Coupler
I bought a Perrin TMIC Coupler (throttle body hose) directly from Perrin, and installed it with the AVO TMIC. The Perrin TMIC Coupler appears to be an exact replica of the stock throttle body hose but formed of silicone and looks pretty. When I removed my stock throttle body hose, one of the infamous rubber rings inside the stock throttle body hose was already falling off, so I'm glad I bought the Perrin hose.
I do not believe I have much to add beyond GTeaser's write up of the Perrin TMIC Coupler besides fitment notes with the AVO TMIC. In sum, the Perrin TMIC Coupler fit well with the AVO TMIC.
AVO TMIC Fitment
In brief, The AVO TMIC fit great after some careful and patient installation as shown in the below photos. The AVO TMIC uses the stock rubber grommets (cushions per Subaru), which are removed from the stock TMIC and on placed onto the AVO TMIC - a nice touch.
After replacing the stock throttle back hose with the Perrin, I slid the AVO TMIC onto the Perrin TMIC Coupler, and then onto the charge pipe (intake duct B per Subaru). The TMIC did not line-up with the stock mount points (intercooler stay RH & LH per Subaru) that first couple times, and thus, I removed the TMIC, marked the top of the coupler, rotated, or clocked, the coupler about 10-15%, and re-installed the TMIC until it perfectly lined up with the stock mount points. I suspect that if I hadn't removed the stock throttle back hose and installed the Perrin TMIC coupler (e.g., I suspect that I didn't get the TMIC coupler positioned perfectly the first time), the TMIC would have lined up perfectly the first time. Please note that silicone lube is very helpful when rotating the TMIC coupler and installing the TMIC.
Yikes! The driver's side of the TMIC proximate the BPV valve attachment area did touch, or contact, a portion of the driver's side intercooler stay after installing the TMIC. It didn't appear to affect the fitment but I'm pretty sure it would rub over time and/or provide noise/vibration, and although I don't think it would affect the performance of the TMIC, I find it to be undesirable. I think this has been a problem with other TMICS, but I cannot seem to find the threads/posts on legacygt.com to cross-reference.... To remedy this deficiency, I cut a portion of the driver's side intercooler stay as shown in the below picture.
Additionally, I cleaned the stay and painted it with high-temp paint. I hope that paint doesn't peel and flake all over my engine bay, but my luck is generally terrible.
Lastly, for whatever reason, I really like the stock engine cover, and was pleased to find that it fit and lined-up perfectly after installing TMIC.
I will getting a tune in the next couple weeks after I finish up my DP install, and will post some results in this thread.
