Detonation or "knocking" can destroy an engine in no time flat leaving you with a repair bill that can cost you thousands of dollars. So how do you KNOW that you are knocking BEFORE it's too late? The TurboXS KnockLite (TM) will detect even minor, inaudible detonation and flash the multicolored LED to alert you to the knock so that you can do something about it before it's too late. The KnockLite is a must-have product for anyone that is modifying their engine for more power. The KnockLite wires into either your factory knock sensor or into separate knock sensor (sold separately) that is mounted to your engine block.

 
So why drive around hoping that your engine isn't knocking? Drive with confidence with the TurboXS KnockLite!

TECH TIP: As an added bonus, the KnockLite also comes with a programmable shift indicator.
