🛠️ Frequently Asked Questions

1. Does this fit the stock turbo or only aftermarket upgrades??

While this hose has a 3-inch diameter for high flow, it is typically designed to fit the standard turbo flange. However, if you have a significantly larger aftermarket turbo, you should verify if the inlet diameter matches the compressor housing.

2. Is this compatible with the CVT transmission WRX?

Yes. The engine bay layout for the FA20 engine remains largely the same between the 6-speed manual and the CVT models, so the inlet hose will fit both.

3. Do I need a Pro-Tune or an Accessport "OTS" map to run this?

Generally, a turbo inlet hose does not require a new tune. Unlike an intake (MAF housing), the inlet is located after the MAF sensor. It improves flow and throttle response but shouldn't alter the air-fuel ratio readings that require a remap.

4. What are the benefits of the "4-ply" construction?

The 4-ply silicone is much more rigid than the factory corrugated plastic. Under high boost/vacuum, the factory hose can collapse slightly; the 4-ply design stays rigid, ensuring consistent airflow and preventing tears.

5.What is the "Nozzle" for?

The nozzle/bung on the side of the hose is for the PCV (Positive Crankcase Ventilation) or BPV (Bypass Valve) recirculating hoses. It ensures you can plug in your factory vacuum lines without needing custom fabrication.

6. Will this make my turbo louder?

Yes. Because silicone absorbs less sound than thick plastic and the interior is smoother, you will likely hear more "turbo spool" and "induction noise" during acceleration.
