Description
Impreza GRB HKS Intercooler 13001-AF014
Code No. 13001-AF014
■Features
- We used R type core for larger size + low-pressure loss for better performance than the stock intercooler.
- The side tank has effective usage of airflow of core bumper open from the intercooler entrance to exit.
- We made it a very short piping layout and a large radius of bending to reduce the bad response caused by the front mount layout. So it will have about the same as the stock intercooler boost pressure spooling.
- Stock intercooler in the engine compartment, the core tends to accumulate the heat from the engine and cause knocking for the starting. Putting the intercooler in front help prevent the knocking and make it unbreakable tuning.
- Core size (600×255.6×103), Stock (170×525×65)
- You can improve performance with normal ECU but using HKS F-CON iS/V Pro for setting let you have more and better performance.
■Components
| Core Assy | R type core (side tank polished) |

| etc. | bracket tromp |
■Test vehicle
| Vehicle | Impreza WRX STI |
| Model | GRB |

■Cautions for Installation
- You need to modify the bumper and size of the battery to B19L size for installation.
- Can’t use with the stock recirculation valve. SQV is installable. (The flange is welded into SQV pipe)
- Need separate Racing Suction Reloaded.
- You don’t need ECU setting for exhaust system tuning, but if you do the performance will get better. With already boost-up vehicles, we recommend the setting with F-CON iS or V Pro for better performance.
- The approximate installation time is 5 to 6 hours

* S Type AL is aluminum polished piping type.
(1) Inner Fin
1. Short type
・Short type that the pitch is optimized for fin shape, for small and light to improve the cooling efficiency.
2. Triangular straight type
・Triangular straight type for less pressure loss of airflow.
(2) Outer Fin (triangular louver type)
・Cooling efficiency improved with louver because of the shorter length and angle of the fin.
・Wide surface of the louver makes it more efficient in cooling.
