DENSOs Iridium Long Life plug is fast becoming the standard for today’s high-tech engines. The properties of DENSOs patented Iridium alloy have broken through the spark plug technology barrier. Employing a revolutionary new 360 laser welding process, DENSO has created a spark plug unlike anything on the market today. Designed for durability under the most extreme conditions, DENSOs patented Iridium alloy is six times harder and eight times stronger than conventional platinum and can handle temperatures in excess of 4,000F.

Good product no problems...

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!!!

  • AnswerQ: Plug Heat Range  Ozpic 2 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.
