Redesigned for 2016, the all new 3rd generation of the AF Knock Monitor from HKS (also known as the AFK) now allows you to combine the 3rd generation AFK with a stand-alone engine management system like the HKS F-Con V Pro, where air/fuel ratios and knock retard can be controlled on the fly. The combined Air/Fuel and Knock monitor in the HKS AFK gives you the ability to monitor your A/F ratio as well as any knock that is occurring.

HKS AFK Monitor:

• Up to two A/F sensors can be used together to measure multiple cylinders or banks of cylinders.
• Includes LCD display/controller, Bosch A/F sensor, and knock sensor. Designed to work with other HKS electronics such as the EVC.
• Digital filter is newly utilized for knocking sensor signal process. This filter enables you to reduce noise from the knocking sensor and engine vibration.

HKS AFK Gen 3 Monitors are currently shipped from overseas and may take up to 2-3 weeks for delivery.
