This new version of the Hondata Boost Control Solenoid Kit that we sell now features 4 ports! For vehicles using a FlashPro, only the following applications are compatible: 2006-2011 Honda Civic Si, Honda S2000, 2007-2008 Acura TSX.

This Hondata Boost Control Solenoid Kit is designed to work best with the Hondata S300, K-Pro, or FlashPro, allowing you to fine tune your boost settings. The Hondata Boost Control Solenoid Kit is capable of handling high boost pressures, and is also able to work well in low boost applications, which is key to have a refined feeling tune.

Hondata also chose to go with a normally closed boost solenoid due to the fact that if there were some type of failure, you will run off wastegate spring pressure to keep boost at a same minimum. This helps prevent catastrophic engine damage and keeps your engine's internals safe. Additionally, this boost control solenoid kit uses 1/8th inch NPT threads, allowing you to use the fitting that are already supplied or upgrading to stylish -AN fitting adapters.
