Features & Product Details

The Grimmspeed Top Mount Intercooler Y-Pipe Kit has been designed to work with factory or aftermarket top mount intercoolers. This is a single piece developed from aluminum casting that has been machined after the casting process to ensure for flat flanges, and a precision fitment. This Y-pipe perfectly distributes and balances the airflow to evenly distribute charged air across the inlet, as well as the tank on the TMIC. 5-ply silicone couplers are included to prevent expansion under high boost settings, but still, offer flexibility which absorbs the vibrations caused by the engine. The 90-degree coupler included in the kit will come a little oversized to accommodate those with aftermarket turbocharger setups in the stock location, however, it can be trimmed to fit your application. 

Additionally, worm clamps, as well as zinc plated hardware will be included to make this Y-pipe ready for the installation.

Note: Fitment is for STI or Grimspeed TMIC only. The elbow coupler is sized to fit multiple turbo setups, some trimming may be required.

My OEM TMIC an its y-pipe finally became an eyesore in my engine bay. Got this along with the TMIC from grimspeed on my list of upgrades to do. Shop reported to properly screw down the clamp on the elbow connecting to the y-pipe, they had to come from underneath the TMIC. Item was well packaged an shipped quickly.

This was not a preformance mod. Rather, replacing failing couplers. I cut the lower one back 1/2 inch to minimize coupler flex for my stock turbo and tmic. I polished the cast welds out just for fun. All is well

She gone. 4 years ago
5out of 5stars

The day started off like usual. Rolled out of bed at 6 this morning and got ready to go to work. It was a brisk January morning and scraped the frost from the windshield. My wife was gone. I didn't know where she was but I wouldn't be surprised if she were was where she shouldn't be. Life had bound me to this woman for 33 years as I sit at my cold desk stroking the gray scruff from my face as 4 days had passed since my last shave. I often found myself gazing out the window during lunch hour as I examine the younger co-workers so full of life, energy, poise. Little did they know that life has different paths, and you only get to choose one path that leads to happiness. And my instincts were wrong. The coffee in the dixie cup grew cold. I had to leave. I grabbed the keys to my 2002 Subaru WRX. My wife was waiting in the parking lot because she knew what time I was leaving. Her car packed with her belongings and accompanying her was her much younger boyfriend. She said she was leaving me and my tired old car. She wanted one last race. After all. we met at the drag strip some years back. We both pulled onto the main road where we lined up at the red light. As my Subaru rumbled, she was in a newer car with all the advanced technology. The light turns green and she gone. She gone. And at that moment in acceleration, I realized that the high-pitched whistling noise came from a torn intercooler coupler. I ordered the Grimmspeed Y-pipe kit and have been happier then I have ever been.

Clean and perfect fit. 4 years ago
5out of 5stars

I needed this to install a grimmspeed intercooler on my forester since it has the smaller stock y pipe. It was a perfect fit, materials are great quality, mating to my vf39 needed a tiny bit of trim on the hose, but it was easy enough with a razor. Hose clamps were also good quality.

  • Q: Fitment for WRX OEM Intercooler  Kellen Morse5 months ago

    I see that it says fitment isn't confirmed for the OEM intercooler but why is that? If i trim the silicon it looks like it would fit. Thought?
    • 1 of 1 people found the following answer helpful

      A:  Honestly, I'm not sure. It seems like it would fit but with Grimmspeed saying it is only for the STI and Grimmspeed TMIC, I would tend to believe them. And it may not be just a matter of trimming, the length from the top of the y-pipe mount to the bottom, might be just physically too long for the WRX intercooler. Hope this helps. Thanks

      A:  The mounting locations for the two bolted down portions of the Y-pipe are in a different location than the WRX OEM intercooler. I found out the hard way, but luckily I have an aftermarket turbo now and will be upgrading to a new Grimmspeed intercooler in the near future so I will be able to use the Y-pipe after all.

  • Q: td04 turbo fitment  Heathen7 months ago

    So I'm looking into moving to an STI intercooler but I know that my stock turbo is smaller than the STI's so I am just wondering what 90 degree pipe would I need to get this to fit my stock turbo or would this one still work?
    • 0 of 0 people found the following answer helpful

      A:  This one would work just fine for you :) It comes with a bit of additional length for your exact setup. Thanks!

  • Q: What is included.  Isaac d1 year ago

    Does this kit come with the y pipe gaskets connecting to the intercooler?
  • Q: Fitment  Arthur2 years ago

    It's my understanding that the 06-07 WRX and 04-07 Forester XT have the same intercooler. I'm not too concerned with the fitment of the 90 degree coupler, but does the bolt patter match up?
