2015-2021 Subaru WRX FA20 Super Power Flow Filter by HKS
The SPF (Super Power Flow) filter by HKS enhances typical turbo intake sound and improves acceleration response.
There is no significant improvement in the maximum output, but the torque in the low to mid rpm range is increased, making it more comfortable and improving drivability. In addition, it doesn’t require ECU recalibration.
The green SPF body and black alumite heat insulator with HKS logo improves engine bay appearance.
