Multiquip 9807956846 Spark Plug BPR6EX (NGK)

The Multiquip 9807956846 Spark Plug BPR6EX (NGK) is a genuine OEM spark plug designed for a wide range of Multiquip, Whiteman, and Essick equipment powered by compatible gasoline engines. This NGK BPR6EX plug is specified across plate compactors, walk-behind and ride-on trowels, mortar and concrete mixers, trash and centrifugal pumps, rollers, generators, screeds, masonry saws, and more — making it one of the most versatile service parts in the Multiquip portfolio. Compatible model families include MVC and MVH plate compactors, WM and EM mixers, QP and QPT pumps, CA and J Series trowels, AR rollers, and many others. Keeping the correct plug on your shelf means faster service turns and less time sourcing parts mid-job.

Key Features

• Genuine OEM NGK BPR6EX Specification: — Matches the original heat range, electrode gap, and resistor-type design specified by Multiquip engineers for these engine configurations, ensuring correct combustion timing and ignition reliability.
• Drop-In Engine Fitment: — Thread pitch, reach, and hex size match OEM requirements for a straightforward installation with no modification to the cylinder head or ignition lead.
• Broad Cross-Equipment Compatibility: — A single part number covers compatible plate compactors (MVC60, MVC82, MVC88, MVH208GH, MVH308GH), mixers (WM45, WM63, WM70, WM90, WM120, MC64, MC94, MC12PH, EM70, EM90, EM120, PRO12), trowels (CA4HM, CA4HC, CA5BC, B46, J36-M30, HDA Series, BS90C, BH90C, JH90C, JS60C), pumps (QP2TH, QP3TH, QP4TH, QP205SH, QP303H, QP402H, QPT205SLT, QPT305SLT), rollers (AR13H, AR13HA, MRH800GS), generators (GA2.5HR, GAC2.2HZ, GAC2.5HR), and additional equipment lines.
• Consistent Ignition Performance: — A correctly specified spark plug sustains clean ignition across the RPM range, supporting full engine power output and smooth throttle response. A worn or incorrect plug causes hard starting, misfires, and increased fuel consumption.
• Fuel System Compatibility: — The resistor-type (R) construction suppresses electromagnetic interference, protecting any onboard hour meters, tachometers, or control electronics present on equipped models such as MVC VTHW series compactors.

A spark plug initiates combustion by creating a precisely timed electrical arc across its electrode gap, igniting the compressed air-fuel mixture inside the cylinder. The heat range of the plug — indicated by the "6" in BPR6EX — determines how quickly the plug tip dissipates heat; using the wrong heat range risks fouling at low temperatures or pre-ignition at high loads. Over time, electrode wear widens the gap and increases the voltage required to fire, leading to misfires, power loss, difficulty starting, and elevated fuel use. Replacing the plug at recommended service intervals with the correct OEM-specified part restores reliable ignition and protects engine internals from the stress of incomplete combustion.
