1. Iridium power best demonstrates its performance improvement during acceleration
2. Iridium center electrode and a specially shaped ground electrode.
3. High-response driving with fewer misfires than under higher required voltage spark conditions,
and fewer misfires when ignitability is difficult.
4. Outstanding acceleration, high fuel efficiency and durability.
5. Corrugated Ribs Prevent Flashover.

How to Read Your Spark Plugs
Is your engine running too lean? Too rich? Is there an issue with oil control or ignition timing? Or is everything just fine with your engine? Like the mechanical version of the Magic 8-Ball, your spark plugs may have the answers for you. The trick is learning how to read your spark plugs.
With help from the spark plug experts at Beyond First Auto, we’ll teach you how to diagnose minor tuning issues or potentially major engine problems by examining your spark plugs. Check out the images below, courtesy of Spark Plugs, and get ready to do a little light reading the next time you pull your spark plugs.
Normal
Appearance: A light tan/gray or brownish color, along with very little electrode erosion, indies optimal operation conditions, including a healthy engine and correct spark plug heat range.
Deposits
Appearance & Symptoms: The electrodes—center and ground—are covered in an ashy coating. As a result of this masking of the electrodes, your engine may experience a misfire. This build-up of combustion deposits can eventually (but not usually) fill in the space between the two electrodes.
Possible Causes: Oil leaks, poor fuel quality.
Wet and Dry Fouling
Appearance & Symptoms: Dry fouling (top) appears as sooty, black build-up. Wet fouling (bottom) has a wet, sometimes oily appearance. Both conditions can create poor starting and misfiring.
Possible Causes: Depending on whether the spark plug is coated in oil or fuel, wet fouling can be symptomatic of a compromised head gasket, poor control from your pistons’ oil control ring, valvetrain problems, or an extremely rich condition. Dry fouling, or carbon fouling, is often caused by an overly rich condition, and the problem may lie with your air cleaner (clogged) or carburetor. Other possible causes could be low compression, vacuum leak, overly retarded timing, or improper spark plug heat range.
Lead Fouling
Appearance & Symptoms: Lead fouling can only occur in appliions that use leaded gasoline, such as racing engines. Lead fouling generally shows up as yellowish brown deposits on the spark plug’s insulator nose. Lead fouling can cause your engine to misfire only at high-rpm and under hard acceleration.
Possible Causes: This condition commonly occurs when gasoline contains too much lead; however, because spark plugs are changed frequently in racing appliions, lead fouling has become less common.
