Multiquip 0655 Spark Plug Cap

The Multiquip 0655 Spark Plug Cap is a genuine OEM ignition component designed for a wide range of Multiquip equipment, including plate compactors (MVC70E, MVC70EW), rammers (MT60H2), ride-on and walk-behind power trowels (HTX, STX, HTN, HHN, JWN series), roller screeds (WRS5200, WRSPUDF), backpack vibrators (BPX series), water trailers, and flat saws (SP1G, SP2S20H). As a genuine Multiquip OEM part, the 0655 is manufactured to the same specification as the original component installed at the factory, ensuring a direct, accurate replacement across all compatible models. Sourced and fulfilled by DHS Equipment, this part ships with full confidence in fitment accuracy. Whether you are servicing a trowel, compactor, screed, or vibrator, having the correct spark plug cap on hand keeps ignition systems performing as intended.

Key Features

• Genuine OEM Ignition Integrity — Manufactured to Multiquip's original specification, delivering the correct terminal resistance and boot seal integrity required for consistent spark energy transfer.
• Direct Plug-and-Play Connection — Engineered to seat securely onto the spark plug terminal and ignition wire without modification, maintaining a weatherproof connection that resists vibration-induced loosening.
• Broad Multi-Equipment Fitment — Compatible across MVC70E/EW plate compactors, MT60H2 rammers, HTX, STX, HTN, HHN, JWN ride-on trowels, BPX vibrators, WRS roller screeds, SP-series saws, and water trailers.
• Protects Ignition System Reliability — A cracked, loose, or failed spark plug cap causes misfires, hard starts, and erratic engine performance; replacing it with a correctly rated OEM cap restores clean, consistent ignition.
• Electrical Safety Compliance — The insulated boot prevents high-voltage ignition current from arcing to surrounding components or operator contact points, making cap condition a genuine safety consideration during routine service.

The spark plug cap is the terminal connector that joins the ignition wire to the spark plug, delivering the high-voltage pulse generated by the ignition coil to fire the engine's air-fuel mixture. A properly functioning cap maintains a secure, insulated connection that resists moisture, vibration, and heat — all conditions common in compaction, finishing, and concrete equipment. When the cap deteriorates, cracks, or loses its internal spring contact, the result is a weak or intermittent spark that causes difficult starting, engine misfires, or complete failure to run.
