HKS 44006-AK003 Air Fuel Knock Amp AFK Wideband Controller

 

Redesigned for 2008, the all new generation of the A/F Knock Amp, known as the AFK, now includes a new HKS AF sensor where the air/fuel ratio can be monitored accurately on the display. The AFK can now monitor and display dual A/F readings with the purchase of an additional AF sensor. The redesign of the new AFK features a sleek black case with a clear acrylic faceplate and a positive lit LCD offering a sophisticated look to match the new EVC.

 

The HKS AFK 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.

  • Includes a plug and play HKS AF sensor (no modifications or atmospheric calibration necessary).Simultaneous dual A/F monitoring.
  • Simultaneous dual A/F monitoring.
  • Additional sensor required for dual A/F monitoring (Sold Separately)
  • Easier set-up for Knock Detection.
  • Sleek and clear acrylic faceplate with positive lit LCD display to match the new EVC.

Almost blew up my microwave
Size: 20 Ounces, Size: 20 Ounces
TL;DR "A hilarious microwave mistake turned into a great home cafe upgrade. This 20oz cup is straightforward to handle, looks incredibly professional, and holds a level of heat that will literally burn you if you aren't careful." . Bought this for homemade coffee brewing, just to spice things up. But as I go ahead to heat up my new shiny stainless steel milk frother cup in the microwave, whoopdy doo. Ya can’t put stainless in the microwave! Regardless, it’s still a straightforward frother cup to handle, making it a great dollar investment for upgrading my home cafe setup. . 1. Spotless Stainless Steel: Its sleek appearance made me feel professional in the hands of an amateur like moi. Great quality! 2. Temperature Retention: I accidentally burnt myself because it stayed so hot, but that is a major positive. Proving the insulation works perfectly and keeps the milk piping hot. 3. Size: The 20oz capacity is accurate, providing the perfect amount of space for frothing without any overflow.
