GrimmSpeed Top Mount Intercooler Splitter - Subaru WRX (GDA/GGA) MY02-03
Sick of your OEM splitter choking the airflow to your intercooler? GrimmSpeed builds this splitter to fix exactly that, giving your Subaru WRX the ducting its top mount intercooler actually needs. SKU: GRM093074.
This listing covers the Subaru WRX (GDA/GGA) MY02-03 fitted with a JDM STI scoop, paired with a GrimmSpeed or OEM STI top mount intercooler.
Note: This splitter requires a JDM STI scoop and is designed around STI sized top mount intercoolers - it will not suit vehicles running the factory WRX scoop or standard sized TMIC.
Key Features
- Increases flow capacity to the TMIC by roughly 70 percent over the OEM splitter
- Redesigned vanes for more even airflow distribution across the intercooler core
- CNC laser cut from 5052 aluminium for a lightweight, fatigue resistant structure
- Finished in durable DuPont black powdercoat
- Includes custom EPDM rubber gasket for a proper seal
- Provisions for up to three intercooler sprayer ports
- Flathead riveted assembly instead of welded joints
Vehicle compatibility, OEM part numbers, and fitment notes are provided in the tabs above. Please confirm your scoop type and intercooler setup before ordering.
