Spark Plug Information
While looking for spark plugs for my Vortec heads I ran into this AC chart and thought I would share. I had been using to short a plug in mine and found that the Vortec heads (iron) need the LTS style.
R - Resistor 4- 14mm thread 3- heat range LT - Long reach, .715" (18.16 mm), Tapered Seat T - Tapered Seat Shell Design TS - Tapered seat with extended tip LTS is a long reach tapered seat plug with a extended tip. TS it a tapered seat plug with a extended tip.
