BMW F30 340i Spark Plug Set

SKU F30-340I-SPARK
Price

$59.99

Spark plugs ignite the air-fuel mixture in each cylinder; worn plugs can cause misfires, rough idle, reduced power, and poor fuel economy. This set replaces all plugs together for consistent performance across every cylinder.

Designed to fit the BMW F30 340i (N55 turbo inline-six), matching the factory thread size, reach, and heat range.

Quality electrode material delivers reliable ignition and smoother, more efficient engine operation.

Reference: OE/interchange BOSCH

"The socket set is top-tier quality. Heavy-duty steel that handles real torque without slipping. Better than the big box store brands honestly."
