Subaru XT Spark Plug

BOSCH SUPER CLASS PLATINUM+2 SPARK PLUG

Bosch Super Class Platinum+2 Spark Plug uses surface air gap firing technology and dual yttrium enhanced ground electrodes for longer life and has more platinum for smoother acceleration and optimum engine performance.

Specifications:

• 14 mm thread size
• 19 mm reach
• 20.6 mm hex size
• Platinum plug
• Gasket seat style
• Interference suppression resistor
• Surface air gap plug
• Heat fused platinum center electrode
• 2 ground electrodes
• Heat range 8

Features:

• Fine wire platinum center electrode which is heat fused into the extended ceramic insulator reduces the voltage necessary to jump the gap as well as reduces quenching
• Reaches self cleaning temperature faster for quicker starts and increased fuel efficiency
