K&N Boost Control Modules

K&N boost control modules instruct the vehicle's ECU to increase the amount of pressure in the manifold to a higher level before releasing it through the wastegate, keeping more boost available for when you need it. The module reads the MAP (manifold air pressure), preventing over-boost and ensuring that power is added safely. Everything you need to set up your boost control module, including the control module, wiring harness, adjustable control dial, and complete instructions are included. With an easy plug-and-play installation, it can typically be installed and ready to use in 30 minutes or less!

Features Include:

* Improved throttle response
* Works within factory parameters to increase boost
* No software required and adjustable on the go
* Compatible with other performance upgrades
