Description

GrimmSpeed Stage 1 Power Package - 2008-14 Subaru STI (GRM191004)

GrimmSpeed Staged Power Packages combine components designed and tested to work well together as a complete system, instead of piecing together parts from different manufacturers. The Stage 1 Power Package is an excellent place to start. The GrimmSpeed 3-Port Boost Control Solenoid offers more accurate and more responsive boost control and is a must when having the vehicle professionally tuned. The GrimmSpeed intake reduces pre-turbo restriction, letting the turbo build boost more quickly and efficiently.

Important: that all GrimmSpeed Staged Power Packages require a proper tune.

Included components

  • GrimmSpeed 3-Port Electronic Boost Control Solenoid
  • GrimmSpeed Cold Air Intake System

Features

  • Decrease spool time: lower intake restriction and better boost control
  • Plug and play into OEM harness: no splicing wires like other BCS solutions
  • Hybrid cold air/short ram design
  • Air straightener dimensionally mimics the factory configuration for accurate MAF sensor readings
  • MAF sensor location inside the heat shield, isolated from engine bay heat
  • Custom reusable high flow air filter with integrated velocity stack entrance
  • 60 minute installation with written and video guides

with the package and a tune, expect a decrease in time to spool, rock solid boost control and an increase in torque and horsepower. The solenoid keeps boost in the system instead of bleeding it away like the factory configuration, and the intake decreases restriction before the compressor.
