4 Port Boost Controller

The Hondata 4 port boost control solenoid offers enhanced control over your engine's boost pressure. By precisely directing pressure to both the top and bottom of the waste-gate diaphragm, it allows for significantly lower waste-gate spring pressure. This results in better low-gear boost control and perfect high-gear, high-boost performance. It features a normally closed design, ensuring that in case of failure, the system reverts to operating off the waste-gate spring to prevent over-boosting. With features like "Better spool-up and mid range power" and "Better duty cycle control," this boost controller can help achieve over 50 psi of boost when used with a 10 lb waste-gate spring. The unit utilizes 1/8th NPT fittings, which can be adapted to AN fittings. It is compatible with Hondata S300, K-Pro, and FlashPro tuning platforms, including specific applications like the 2006-2011 Honda Civic Si, Honda S2000, and 2007-2008 Acura TSX. If upgrading from a 3-port solenoid, re-tuning of the boost control tables will be necessary. The product is listed under Universal Parts, specifically within Forced Induction and Turbo Boost Controllers. While the product page states "This part does not have vehicle specific fitment," detailed compatibility is provided for specific Honda and Acura models when used with a FlashPro tuning system, including the 2006-2011 Honda Civic Si and 2004-2008 Acura TSX.
