Step 3: Indexing Your Spark Plugs

Hi Friends,

Indexing your spark plugs is another step you can take. This should give you approx. one more horse in the area of horsepower. What you want to do is take the open end (called the gap) of your spark plug terminal and place it toward the intake of the head. Simply make a mark where the gap is and put your spark plug in its proper space like normal. Just do the best you can to line up the mark you made with the intake side. To be safe you may want to buy two sets of spark plugs in case you an't get it the first time, and if you succeed in installing them the first try you will have an extra set for when they need to be changed.
