What it does

Boost changes need fuel and tuning to match, or the engine can run lean. Air and fuel parts decide how well the engine breathes and how cleanly it runs, so the right part restores smooth running and can support more power on a modified engine.

Installation & tips

  • Change fuel and tuning together with boost, and check for leaks with a boost leak tester.
  • Tuning: Most boost changes need a tune.
  • Couplers and clamps: Old couplers split under boost.
  • Put the new part next to the old one and compare the shape, mounting points and connections before you install it.
  • Work on a cool engine with the vehicle secured, and use a service manual for your vehicle for torque specs and procedures.
