Features & Product Details

Once you start performing modifications that increase horsepower and torque such as a turbo-back exhaust system, intake, injectors, and a tune, going to a colder spark plug is required.

These are a 1-step colder spark plug, and it has been designed to provide durability under the most extreme of conditions, and the featured patented iridium alloy is six times harder and eight times stronger than conventional platinum, and can handle temperatures in excess of 4000°F. 

Note that these are sold individually.

Good product no problems... 4 years ago

Good problems no need to blame on the product because it is a pain to install the plugs on Subaru vehicles. These are great replacement for stock plugs that cant handle all the power adder mods.

Plugs simply didn't give enough fire to start my car. I was very disappointed. Switched to stick NGK plugs and started right up. Was a huge hassle because STi engines are a pain in the ass to change the plugs on.

Big difference on the response, especially when paired with my okada plasma direct coils, a must have for your sti or wrx and you can get the coils from RSD. RSD once again the BEST!!!

QUESTIONS & ANSWERS

  • Q: Plug Heat Range  Ozpic4 years ago

    Why one step colder ? this is an issue that has always confused me as people I have spoken to seem to have a different take on the subject,so if some one can clear this up without getting to technical I sure would appreciate it.

      A:  The idea is to go one step colder per 75-100HP you add. This helps prevent predetonation and knock.
