Link G4 KnockLink Kit - Includes Knock Sensor+Loom (G4KNLK)

Kit includes the G4 KnockLink visual warning light and a knock sensor with loom. The KnockLink is a self-calibrating, visual knock warning tool. This kit is designed for tuning, street and race use.

The G4 KnockLink is the only detonation warning device on the market that requires no setup. Other systems require time consuming gain, frequency and noise settings to be adjusted. Without proper knock listening tools, this can prove difficult if not impossible. The KnockLink requires none of this, just wire in and start the engine.

If you have a deadline to meet, please confirm that we have stock ready for dispatch to avoid disappointment!

Product Info

Even light detonation will damage an engine over time. The G4 KnockLink's microprocessor continuously scans the knock signal and warns for any knock occurring. The engine's RPM and load is automatically 3D profiled by the KnockLink, continuously storing and dynamically adjusting this noise profile map while looking for the particular knock frequency.


Operation is simple. The colour of the LED represents four different modes:

Dim Blue - KnockLink is powered, waiting for the engine to be started
Flashing Blue - KnockLink has detected the engine has started and is now calibrating
Dim Green - KnockLink is adapting to the engine's noise profile and listening for knock
Flashing Red - KnockLink has detected knock. Avoid large throttle openings, seek professional advice
