Upgrade your turbo induction system with this dual-port blow-off valve engineered specifically for the Mitsubishi Lancer Evolution 8, 9, X, Ralliart, Colt GSR, and 3000GT/GTO platforms. Designed as a direct bolt-in replacement, this aftermarket unit stops boost pressure leakage when you lift off the throttle, protecting your turbocharger from compressor stress and maintaining consistent spool timing between gears. The split 50/50 outlet configuration balances internal pressures smoothly while delivering the aggressive flutter sound turbo enthusiasts look for. Built from CNC-machined aluminum and finished with a protective anodized layer, the housing withstands extreme under-hood heat and road debris without corroding or warping over time.

Benefits & Tips

  • Route the vacuum hose to a manifold tap located after the throttle body to ensure accurate boost-triggered actuation during full-throttle run-on.
  • Use a thread-locking compound on mounting bolts if your vehicle has experienced vibration, but leave the valve spring tension unadjusted to preserve factory calibration.
  • Inspect the silicone couplers for cracks before every track day; replacing aged tubing maintains airtight seals and prevents sudden boost drops.
