For high-HP modified Subaru WRX and STI that need a larger MAF housing. 73mm MAF diameter is good for up to about 400-450 awhp. Cold-Air Intake puts the filter high inside the filter: Cooler air = more power.
- High filter position keeps intake away from puddles.
- Fits directly onto the turbo inlet (stock, silicone, APS, or AP). No MAF Elbow required.
- Reusable ultra-high-flow K&N filter. Optional Amsoil oil-free filter (see related products below).
- Works with TurboXS/Perrin/APS-style front-mount intercoolers (WBR & UR too) and all top-mount intercoolers.
- Highest-quality construction:
- Smooth mandrel bends
- CNC-machined MAF flange.
- Beautiful welds by ASME-certified welders.
- Reinforced silicone couplers.
- Designed, Tested, and Manufactured in the USA
Absolutely positively requires engine management and tuning!
Picture is not item specific.
Note: KSTech intakes can be made without the MAF flange.
