Gen 2 Powerdex AFX Air/Fuel Ratio Wideband Kit
NGK90067
Gen 2 Powerdex allows closely monitoring air/fuel ratios when maximum performance is desired. With fast response time and accuracy within 0.1 AFR,
unit includes an expanded, selectable range of 9:1-16:1 (default) or 9:1-20:1 AFR and the addition of a selectable analog output. Unit is compact for easy
placement and mounting. Sold with wiring harness, wideband sensor, exhaust boss and plug, and tuning manual.

NGK V-Power Racing Spark Plugs
The unique design of the V-Power spark plug directs spark to the edge of the electrode where it
can more effectively ignite the air/fuel mixture and reduce the quenching effects of standard spark
plugs. V-Power plugs use a solid copper core, longer insulator nose and a large, 2.6mm center
electrode for extended plug life and maximum performance.
Please refer to page 730 for the spark plug cross reference chart.
