Turbosmart IWG75 97-07 Subaru Impreza WRX 7 PSI Black Internal Wastegate Actuator

This is the Turbosmart IWG75 internal wastegate actuator, designed specifically for your 2004-2007 Subaru Forester. It's a direct replacement for your factory actuator and is set to 7 PSI, aiming to give you better boost response from your stock turbocharger. If you're looking to get more out of your turbo without going to a completely different setup, this is a solid option.

The main advantage here is the improved 'Working Ratio' compared to the stock unit. This means the actuator can react more quickly to changes in boost pressure, helping to keep your boost levels more consistent and improving overall response throughout the RPM range. It's built from high-grade billet aluminum, which is a strong material that holds up well under the heat and pressure of the engine bay. Turbosmart also uses a proprietary silicon Nomex diaphragm, known for its durability and ability to handle temperature fluctuations. The unique locking collar system makes adjustments, if you ever need to change the spring later, straightforward.

This actuator comes pre-set at 7 PSI, but Turbosmart offers optional springs if you want to run higher boost levels down the road. It features stainless steel rods and clevis for corrosion resistance. Keep in mind this part is not CARB approved and cannot be shipped to California.
