The goal when developing our new top mounted intercooler was to make it the very best aftermarket top mounted intercooler for WRX/STi... period.

We studied our competitors products and fixed all of the mistakes they have made...some of them major.The most obvious error that EVERY one of our competors makes is not supplying their intercooler with proper ducting/shrouding to suit the increased size of the new intercooler. There is no point in installing a larger intercooler and leaving the factory under bonnet splitter/scroud in place.

Here is the solution. A properly sized splitter/shroud to suit the application.
