The HKS Air Fuel Knock Amp 3 is an electronic monitoring device that displays two of the most vital engine conditions; engine knock and air/fuel ratio. Knock occurs when there is abnormal engine combustion, known as detonation, caused by a combination of improper A/F ratios and ignition spark. This can rob power, reduce engine longevity and even lead to catastrophic failure. The A/F Knock Amp utilizes the factory knock sensor allowing you to monitor, in real time, engine knock visually and audibly via headphones (not included). A warning function can be set for both engine knock and air/fuel ratio where an audible alert sounds if the preset warning is reached. Get this and all your JDM at RHDJapan!!
