THIS PRODUCT IS CURRENTLY DISCONTINUED BUT PLEASE CONTACT US IF YOU WOULD LIKE TO JOIN OUR GROUP BUY WAIT LIST. When contacting us please specify if you have an 04-07 intercooler or an 08+ intercooler.
Once you swap your GC, it’s critical to make sure the air is forced through the intercooler to maximize its effectiveness which translates to the engine making more power because of the colder air.
Our intercooler splitter (or hood undertray air diverter) is designed for stock 2004-2007 or 2008+ STi intercoolers in stock STi engines. It will also work for WRX engines with STi intercoolers but may need a bit of adjustment for the correct fitment due to the small differences in each custom swap.
In our pursuit to build parts that bridge the gap between new and old, we have built an Intercooler Splitter with cutouts for optional water spray nozzles for 1998-2001 Impreza hoods. The splitter is designed to work with 2004-2007 or 2008+ STi Intercoolers.
For those who are using this for a JDM V7-9 application, the USDM STi fitment is going to be pretty good. The distance from front to back of the intercooler is a touch bigger but not enough to cause any issues.
If during your swap or project you've gotten rid of the nozzles, clip, or taping screws you can buy them with the Intercooler Splitter as a set or click here to buy the pieces individually.

"Seems like it was built well. Fits right inside the intercooler and the holes for the shroud line up with my hood."
