Original Denso Nissan standard plug - Tested OK no misfire but lagging after 4000rpm 2. Bosch Super4 - Tested- bad misfire upon accerleration but more power from 3000-6000rpm 3. NGK Platinium G-Power - Tested - no misfire when cold upon accerleration but will mild misfire when hote, power is smooth from 2000-6000rpm 4. Denso Iridium - Tested but bad misfire upon accerleration but less misfire after regap to 0.8 and very power from 3000-6000rpm Why the original plugs gave the best firing capacity? It it true that platinium and irridium plugs create less sparks but prolong plugs life [/QUOTE]
