In alignment with the electrification of transport, Mark Hanson's SeaFoam has introduced a signature 'DesertFroth' proprietary, electric motor additive, beginning with a UL-Rated, 473 mL-sized, entry-level portion, good for 15-kWhs, which installs between the charge-coupling and charger infrastructure.
It's purported to prevent buildup of electron and magnetic flux residues within the rotor/stator air-gap, which could potentially rob performance.
Look for it wherever SeaFoam is presently sold.
