If your customers often complain about unstable vehicle idling, rising fuel costs and frequent spark plug replacement, you may have ignored a hidden flaw of cheap spark plugs — magnetic ground electrodes.
We did an on-site magnet test for comparison:
Ordinary low-cost spark plugs use ferrous magnetic ground electrodes. Tiny iron particles worn off from the engine will stick to the ignition gap constantly during driving. The accumulated metal scraps will destroy the standard spark gap step by step, resulting in insufficient combustion power, rough shaking during startup, and the electrodes will burn out prematurely within a short mileage.
Our factory upgraded all spark plugs with non-magnetic ground electrodes. No metal filings can attach to the ignition area at all. The spark gap keeps the original standard size for long-term use, which helps vehicles burn fuel fully, cut down fuel waste, and extend the service life of both spark plugs and the engine.
All our spark plugs fit Toyota, Honda, Nissan and other Japanese vehicle series. We provide factory direct wholesale without intermediate markup, support small trial orders and full container shipments to Southeast Asia, Russia and Africa.
