Bosch 4419 Platinum +4 Spark Plug FGR9DQP

The Bosch 4419 Platinum +4 spark plug features revolutionary surface air gap firing technology that delivers superior engine performance and fuel efficiency. This advanced spark plug combines a pure platinum center electrode with four yttrium-enhanced ground electrodes to provide the longest, most powerful spark for optimal combustion.

Key Features:

• Four yttrium-enhanced ground electrodes provide maximum access to the air/fuel mixture for efficient combustion and extended service life
• Heat-fused platinum center electrode ensures consistent performance and resistance to wear
• Surface air gap firing technology produces a longer, hotter spark than conventional spark plugs
• Factory-set electrode gap never requires adjustment, ensuring easy installation every time
• Yttrium alloy ground electrodes resist oxidation and gap wear for long-lasting performance

Bosch Platinum +4 spark plugs deliver smoother acceleration, improved throttle response, and optimum fuel efficiency. The unique four-ground electrode design provides superior ignitability compared to single-electrode spark plugs, making this an excellent choice for drivers seeking enhanced engine performance.
