Moroso 71900 Spark Plug Indexing Washers
These Moroso indexing washers are designed for use on all 14mm spark plugs with 5/8" hex. Enter your model number to make sure this fits.
Reviews
"These little gems let you angle the electrode of your plugs away from the intake valve which makes the fuel burn a little more quickly and efficiently: the "shadow" of the electrode faces away from the incoming fuel/air mixture. When you add one to a spark plug, the thickness causes the plug to rotate left approximately 1/4, 1/2 or 3/4 turn respectively."
"It can work out well for you if you take your time."
"Indexed the plugs on my 2015 EcoBoost Mustang quickly and hassle-free."
"Easy to use."
