Bosch 8513 EVO Iridium Platinum Spark Plug for Turbocharged GDI Engines

The Bosch 8513 EVO spark plug is engineered to deliver maximum ignition performance in the extreme combustion environments of modern turbocharged engines with gasoline direct injection (GDI). Designed to withstand the high mechanical and performance demands of today's advanced powerplants, this premium spark plug features enhanced thermomechanical, mechanical, and electrical strength to resist irregular combustion and mega knocking that can occur under extreme pressures.

Advanced Electrode Technology:

• Laser-welded iridium alloy pin on the center electrode for exceptional durability
• Platinum-iridium alloy plate on the ground electrode for superior wear resistance
• Ultra-fine wire design and tapered ground electrode for optimum ignitability
• Long service life with reduced electrode wear

Enhanced Design Features:

• Improved insulator and housing design for increased head-bending strength
• High dielectric strength greater than 45 kV to withstand extreme conditions
• Optimized gas seal tightness in the cylinder head
• Reduced risk of damage during installation

Installation Notes:

• Pre-gapped at the factory and does not require gap adjustment
• Specially indexed design requires torque wrench installation
• Always torque to the proper specification printed on the package
• Adjusting the gap may damage the electrodes

Bosch EVO spark plugs represent original equipment (OE) quality engineering, developed and manufactured to the same high standards as factory-installed components. Ideal for turbocharged GDI engines in import vehicles including Acura, Honda, and Mazda applications.
