Justin Posted May 28, 2003 Report Share Posted May 28, 2003 I take it the emmisions sticker is missing, because it will say on there. SPARK PLUG TYPE UPDATED BY TSB # 88-T-64 Spark Plug Gap 0.90 mm (0.035 inches) Spark Plug Torque 20 Nm (15 lb. ft.) Spark Plug Type AC R43TS NOTE: Check the gap specifications given on the Emissions Control Label. If the gap is different from what is listed here, use the information on the label.
