Buick Bosch Auxiliary Cooling Fan Information

BOSCH PREMIUM CLASS PLATINUM+4 SPARK PLUG

Bosch Premium Class Platinum+4 Spark Plug contains the most platinum in the Bosch Platinum Plug Series and has a unique firing technology that combines the advantages of surface air gap technology and 4 yttrium enhanced ground electrodes.

Specifications:

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

Features:

• Reduces the voltage necessary to jump the gap as well as quenching
• Provides multiple radial spark paths and surface air gap design that creates optimal exposure of the air/fuel mixture to the enhanced ignition spark
• Yttrium-enhancement of the ground electrodes further extend plug life
• Designed to reach self cleaning temperature faster for quicker starts, smoother acceleration, and increased fuel efficiency

Series: Bosch Platinum+4

Quantity Sold: Sold individually

Warranty: 12-month or 12,000-mile Bosch limited warranty

Part #: BS4418
