Denso "IK24" Iridium Power Spark Plugs: Mitsubishi Eclipse Turbo 1990-1999, Evolution VIII 2003-2005 #31828

Iridium Power® best demonstrates its performance improvement during acceleration. The world's smallest center electrode and specially shaped ground electrode deliver maximum spark energy while withstanding temperatures greater than 4000º F. These features combine to achieve higher ignitability and require lower spark voltage than ever before. As a result, acceleration improves in comparison with normal plugs.

Ignitability That's a Cut Above

To increase ignitability, the important point is to let the flame kernel produced by the spark to grow unobstructed. Normally, this can be accomplished by widening the spark gap. However, this causes spark voltage to increase, which has the opposite effect. Iridium Power uses DENSO's patented U-Groove ground electrode to achieve maximum ignitability while minimizing required voltage.

Features:

• Tapered cut, U-Groove ground electrode
• Worlds smallest 0.4mm iridium center electrode
• Patented 360-degree laser welding assembly process

Benefits:

• Required ignition voltage reduced
• Unsurpassed center electrode durability
• Available for many performance and power sports applications
• Improved spark ignition for maximum combustion, even with lean air-fuel mixtures

Note: Alternative option to the NGK BPR8EIX spark plugs.

Sold in sets of four.
