KnockBlock G4+ (KNB)

This knock-related tool helps you hear or monitor detonation before it turns into real engine damage. It is a smart buy for anyone tuning seriously and wanting better feedback from the engine.

Applications: Link’s G4+ KnockBlock is an audio interface that lets you hear knock (detonation and pre-ignition). Worth buying when you want safer tuning decisions and a little more insurance while pushing the setup.
