These have both been a long time in the making and as the popularity of GrimmSpeed intercooler offerings has skyrocketed, we've had a massive amount of demand for splitter options that maximize performance of our Top Mount Intercooler on the 04-08 FXT platform, with some users producing 600-700whp with them. These splitters are designed to seal perfectly with your GrimmSpeed TMIC, ensuring that the system works as efficiently as possible. With the dense cores that we use, forcing ambient air through the core with a properly fitting splitter is more important than ever and these splitters will allow you to do that with ease.

For FXT and STI owners that are currently using a GrimmSpeed TMIC, this is a must have.
