Detailed Product Description

The NGK Iridium IX Spark Plug 8196 (part number Dcpr6eix) is designed to meet the ignition demands of the BMW M5. Featuring an iridium center electrode tip, this spark plug offers a fine electrode that requires less voltage to produce a strong spark, improving combustion efficiency. The copper core center electrode enhances electrical and thermal conductivity, helping to maintain stable engine performance. The taper cut ground electrode tip design optimizes the spark exposure to the air-fuel mixture, which supports better ignitability and smoother engine operation.

The spark plug’s standard ground configuration with a single nickel ground electrode provides durability and resistance to wear. The removable nut electrical terminal type facilitates straightforward installation and removal. With a pre-gap size of 0.032 inches and a flat seat type, this spark plug ensures proper fit and reliable sealing in the combustion chamber. The 0.75 inch reach and 12 mm thread diameter are tailored to fit the BMW M5’s engine specifications.
