GrimmSpeed Stage 1 Power Package Subaru STI 2015-2021 - Red | 191013-RD

Fitment: This power package is specially designed for 2015 - 2021 Subaru STI models. Features: It's the ultimate all - around Stage 1 package your STI craves. First, there's the GrimmSpeed StealthBox Cold Air Intake in red (Part #: 060078). After long - awaited demand, it's finally here. It's like a perfect blend of the tube and filter from the 08 - 14 WRX intake and the Stealthbox heat shield from the 2015+ WRX intake. With minor design tweaks, it offers similar fit and great performance. Second, the GrimmSpeed 3 - Port Electronic Boost Control Solenoid (Part #: 057007). It's the most complete and user - friendly solenoid on the Subaru market. You can easily tune your OEM boost levels via the factory ECU. The stock solenoid gets unstable at high boost, but this GrimmSpeed one can handle up to 120psi, spooling your turbo faster and providing rock - solid boost control. Finally, the GrimmSpeed License Plate Frame (Pair, grm111002). These frames with raised white lettering make you stand out and scream 'GrimmSpeed'. The kit comes with two frames.

Using your GrimmSpeed Stage 1 Power Package: First, install the StealthBox Cold Air Intake following the included instructions. It'll help your engine breathe better. Next, install the 3 - Port Electronic Boost Control Solenoid. You can use your factory ECU to adjust the boost levels easily. Just follow the settings that suit your driving needs. As for the license plate frames, simply attach them to your vehicle. Note: When handling the boost control solenoid, don't exceed the recommended boost levels as it might damage your engine. For maintenance, regularly check the Cold Air Intake for any debris or dirt. Clean it gently with a soft brush if needed. Keep the license plate frames clean to maintain their look. If you have any issues, refer to the product manuals or contact our customer service.
