HKS SUPER POWER FLOW Subaru WRX 2015-2021 #70019-AF107

Stealth frame is redesigned!

“Hyper Stealth Frame” exceeds the performance of previous Super Stealth frame.
Increasing air intake surface area by 27% improves air intake efficiency.


Bold white HKS logo printed on black anodized back plate accentuates the engine bay!

The outer edge of the funnel is securely fixed to the aluminum back plate. Use of aluminum significantly improves rigidity and durability. Alumite process improves surface of the funnel and also provides a sleek black look.


Light sports



Ambient exposure type air clearner has larger area of induction inlet that increases intake air volume. Engine horsepower and torque become higher than a stock repiacement type.
Without air clearner box, sporty intake sound is created.


Free layout and larger inlet area will increase performance of engine.

* Approximate change period:

Dry type: after 6 to 12 months, or drive 6,000km to 10,000km

Wet type: after 3 to 6 months, or drive 3,000km to 5,000km


For proper product performance, replace the air filter element at regular intervals:

(Recommended) Replace every 6,000-10,000km or every 6-12 months.


* There are certain conditions where, dependig on dirt buildup, the filter may need to be replaced earlier than the above recommended intervals.
