This is suitable for all 4JJ1 engines. It is a perfect upgrade to fit yourself at home, adding bling to your bay as well as the functionality of being able to fit a boost gauge to your vehicle to monitor those epic boost levels the 4JJ1 engine can handle. These fit directly into the map sensor position, and come with a new O-ring keeping it all freshly sealed. Available in a range of colours.
