These spark plugs are the most popular, and best spark plug available for the Dodge SRT-4/PT Turbo. Why? Well, they have excellent heat durability, help provide a consistent spark that will help you have a smoother idle, eliminate any stumbling, and maximize power!


  • Stock heat range- Stock heat range is for cars that are BONE stock with no increase in boost.
  • 1 Step Colder- Is for 90% of SRT-4 /PT Turbo drivers out there, who have increased the boost with a good number of bolt on mods.
  • 2 Steps Colder- For big turbo, big turbo engines only, in the 450+hp range.

These plugs need to be gapped to match your power levels. If you are at stock boost levels, then you will need to gap to roughly .035-.038 thousandths. If you have increased boost levels and are making 275-350 horsepower you should adjust the gap to .030-.033 thousandths. If you are making 350-450 horsepower we recommend .028 thousandths. The more boost you have, the lower the gap.


Price is for a set of four (4)
