rpm) Vortech strongly recommends replacing the factory platinum plugs with NGK

#4177 or Autolite #764 and reducing the spark plug gap down to .032”.

NOTICE

Mustang Cobras produced after 11/1/96 utilize a water pump pulley that employs a

lip on both the front and rear edges (earlier units use a lip only on the rear). The front

lip on the pulley may cause interference with the Vortech supercharger mounting

bracket. For proper clearance, the “1996 style” pulley (Ford P/N F3LY-8509-A) MUST

be installed before mounting the supercharger to the engine. This pulley is available

from your Ford dealer or Vortech Distributor (Vortech P/N 4FK016-081).
