After just turning 115,100 miles on my V8 earlier this week, I figure I should start thinking about spark plugs soon. Are the NGK Laser Iridiums worth the extra $.35 each over the NGK Iridum IX? I haven't searched too deeply on pricing yet. I have checked Rock Auto and the prices are as follows:
NGK Part # 3764 {#3540, BKR6EIX11, BKR6EVX11} Iridium IX $6.09
More Information for NGK 3764
NGK Part # 4589 {#IFR6T11} Laser Iridium $6.45
More Information for NGK 4589
Also, NGK boasts about their strong corrosion resistance and how applying anti-seize is not necessary, do people still choose to use anti-seize? If so, what kind?
Thanks.
