Once I have a larger TMIC, what steps are helpful to increase it’s efficiency?
1. Increase the size of your stock hoodscoop to accommodate the increased TMIC surface area. Maximum efficiency of a TMIC depends on full air flow to the core. This generally means you should obtain a STi or aftermarket larger hoodscoop. 2. Proper ducting/shrouding plays a large role as well. OEM and aftermarket options exist for intercooler ducting/shrouding. This step may require custom trimming to ensure a perfect seal or the addition of an alternate substance to make up the difference if needed. Many people have custom trimmed garage door weather stripping/sealer available from Home Depot or Lowes to fill up any gap between the ducting/shrouding and their TMIC. The end goal of ducting/shrouding is a complete seal between the TMIC and hoodscoop. This ensures that 100% of the air entering the hoodscoop passes through the TMIC core assembly. 3. Additionally, there are OEM and aftermarket options that exist for air splitters. Air splitters divide and route the air coming into your hood
