Brisk® P4 (DR15YIR) - Iridium Yttrium Performance Spark Plug with Resistor

Iridium Yttrium Performance Spark Plug (P4 (DR15YIR)) 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.

Specifications

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
