NGK Iridium spark plugs for Chrysler, Dodge and Jeep 5.7 Hemi engines up to 2008 and 6.1 SRT8 engines

These high-performance spark plugs with a center electrode made of the precious metal iridium are used as original equipment by many manufacturers.
They were developed specifically for the latest engine technologies, but they are also an alternative to the standard type for older models in order to fully utilize performance reserves.

What’s special about it:

• The electrode material iridium is almost resistant to spark erosion.
• Iridium enables particularly narrow center electrodes with a diameter of just 0.6 mm.
• With narrow center electrodes, more of the ignitable mixture reaches the ignition spark. This leads to reliable ignition and better spread of the flame front.

Fits:

5.7 Hemi engines up to and including 2008 (1 level colder than standard candles)
6.1 SRT8 engines (same heat value as standard candles)

Delivery includes:

16 spark plugs
