The Tempest spark plug tray is constructed of high quality metal protecting the spark plugs from damage. Other trays can be prone to tipping and spilling the spark plugs onto the hangar floor rendering them unusable.

The Tempest tray design is sturdy and balanced, reducing the likelihood of tipping, Rubber feet on the bottom of the tray help keep the tray in place on metal workbenches and tool boxes.

The tray includes numbered spark plug slots allowing for proper spark plug organization and rotation.
