Iridium Yttrium Performance Spark Plug (P25 (GR17BYIR-3)) by Brisk®. With Resistor. The center electrode is from special nickel-yttrium alloy with high heat conductivity what enables to optimize thermal balance of active parts of spark plug. Perfectly covers engine’s demand at both low speeds driving with prevalence of cold starts and long-running highway driving. Spark plugs are suitable for use of leaded and unleaded fuel. If you want to upgrade your vehicle with a spark plug that provides more power and faster acceleration, then this Brisk product is just the option. Designed with the latest technological advances, it is proven to provide significant performance gains. The spark plug features the unique, patented design and ensures uncompromising durability. Backed by Brisk’s expertise, it will seamlessly and worry-free serve you for the long haul.

Features
Iridium is 6X harder & 8X stronger than platinum
Long lasting OEM performance replacement
Dual copper core electrodes for more energy
Cut back ground strap for maximum spark exposure
The ground electrode which is cut centred to centre electrode assures the suppression of flame extinguishing effect at cold starts and does not hinder the flame front propagation into combustion chamber
Special alloy which is alloyed by Yttrium reduces essentially the burnings of electrodes and enables the flashover from rather long edge by poor demand for a voltage supplied by ignition system
The Cooper core of ground electrode reduces the temperature by 100 C; thereby it increases a change interval to the value comparable with spark plugs equipped with two Platinum contacts
Iridium contact on the centre eletrode assures a long change interval
The space between reduced diameter of centre electrode and insulator tip enables a fast evaporation of fuel and prevents formation of soft combustion deposits on the insulator tip
The cylindrical ending of insulator tip enables very fast achievement of self cleaning temperature after engine start
The ceramics mass with high content of AI2O3 with increased dielectric strength
The cooper core of centre electrode increases the thermal conductivity and therefore it enables the insulator tip elongation by sufficient thermal value reserve of spark plug
The surface protection Zn/Ni extends the resistance to corrosion
Manufactured to meet or exceed strict quality requirements
Made from high-quality materials for ultimate durability
Designed to deliver trouble-free, consistent performance
Right choice for your vehicle and lifestyle
