Review on NGK (6962) Spark Plug 🔌 - BKR6E: Optimal Performance and Universal Fit by Isaiah Bower

Cheapest ever turned out to be the best spark for my GTII Turbo Golf Simple Physics: Silver, Gold and Copper are the finest conductors of electricity known to man. 1. Pure silver tarnishes with oxygen and is brittle, so it has never been used in spark plugs.2. Gold? Resistant to rust, acid and stains. BUT it is quite expensive, especially in its pure form (18K-24K)3. So it all boils down to copper: cheap, VERY conductive, but decaying pretty quickly. Since the turbo engine pressure absorbs EVERY plug, this is not a problem. Anyone who thinks "more money means better candle” when it comes to platinum candles should consider that platinum, not a very good conductor of electricity, is even more expensive than gold (which is why you get a pin-thick plug electrode). ) and is only for long-term maintenance, NOT for better spark. You will NOT see a platinum spark plug on ANY race car, but you will see them on all older generation cars. (Caddies, Lincolns and Buicks) use them extensively.
