GrimmSpeed Top Mount Intercooler Splitter - Subaru WRX (GDA/GGA) MY02-03
The factory splitter chokes airflow to a bigger top mount intercooler, and GrimmSpeed built this piece to fix exactly that. Laser cut from 5052 aluminium and finished in durable black powdercoat, it's designed to direct far more ambient air from the scoop straight onto the core, giving your Subaru WRX noticeably better heat rejection under load.
This listing covers the Subaru WRX (GDA/GGA) MY02-03 fitted with a USDM WRX scoop, running either a GrimmSpeed or OEM STI top mount intercooler. SKU GRM093073.
Key Features
- Up to 70% increase in flow capacity to the TMIC
- Redesigned vanes for even airflow distribution across the core
- CNC laser cut 5052 aluminium construction
- DuPont black powdercoat finish
- Custom EPDM rubber gasket included
- Provision for up to three intercooler sprayer ports
- Riveted assembly instead of welded for long term durability
Vehicle compatibility, OEM part numbers, and fitment notes are provided in the tabs above. Please confirm your scoop type and intercooler setup before ordering.
