The TurboXS boost control solenoid for 2008–2015 Mitsubishi Evolution X replaces the factory two-port solenoid with a three-port unit to improve boost control when running an aftermarket downpipe or upgraded turbocharger. The direct-fit replacement is intended to enable more precise boost management under modified forced-induction setups and is specified for Evo X applications where enhanced boost regulation is required.
