In the vast majority of cases we dispatch same day or within 24 hours. We use couriers for most deliveries. UK is usually next day, rest of the world is usually 3-5 days.
If you are unsure of the knock frequency of your engine, please use our Knock Calculator as a guide. The frequency does not have to be an exact match as the KS-3 and KS-4 will also analyse frequencies either side of the set value.

Yes, our products have been installed on wide variety of vehicles from motorbike engines, Ford Escorts, Honda Civic Type R, Mitsubishi EVO, Nissan Skyline, Subaru Impreza, Toyota Supra, Ultima GTR and a 2,000 BHP Big Block V8. To date there have been no compatibility issues.
The knock sensor should ideally be mounted on the block in line with the point of ignition. In some vehicles this is not an easily accessible location. The KS-3 and KS-4 should still give excellent results provided the sensor is mounted in a location where it is directly coupled to vibrations from the block. Try to avoid locations of excessive heat or where vibrations may be received from other components (VVT solenoid, Throttle body, etc).
The KS-3 was designed as a Knock Monitoring/Warning device. It can be permanently mounted to the dashboard and can be used to alert the driver if knock is detected. The Knock Analyser Pro is designed for engine tuners and rolling road operators who wish to listen to the engine whilst tuning or during a dyno run. Both units can be used independently or connected together using our interface pack. See knock monitoring solutions for more information.
Yes. The KS-3, KS-4 and Knock Analyser Pro work on a “V” configuration. We recommend the Twin Sensor Cable Accessory in these applications.
See our video clips demonstrating the KS-3 in action clearly detecting engine knock. Towards the end of the demonstration there is an audio sample of knock.
The KS-3 does not require an RPM input to detect knock at low RPM. The KS-3 uses a dedicated knock microprocessor that detects knock throughout the entire rev range.
An initial calibration run is required. This involves running the engine through the complete rev range where the engine is known to be operating correctly (i.e not knocking). A Professional Engine Tuner might reduce the boost slightly or retard the ignition for the configuration run.
The Phormula KS-4 will allow you to log engine knock alongside the data that you currently analyse whilst mapping.
The sensor has a hole through the middle and ideally we would recommend using a bolt through the centre of the sensor into a boss on the block.
