About 50 million years ago an asteroid crashed into Earth and wiped out the dinosaurs. What was left behind is a layer of Iridium-rich clay all over the world. They should have left the Iridium buried!

Stop playing around with spark plugs that feature Iridium electrodes, Platinum electrodes, Copper electrodes, fine wire electrodes, split electrodes, ring electrodes or multiple electrodes - get serious with silver electrodes! Silver is the best electrical and thermal conductor of any metal. This makes Nology Silver the best spark plugs in the world.

Nology Silver plugs feature:

• Silver Center Electrode
• More Spark Power

If you have any of these symptoms it might just be time to check and change your plugs.
