The NGK COP Ignition Coil Multi-Pack line reflects NGK’s focus on ignition components, with manufacturing and testing supported by an ISO 17025 accredited lab. This part number, 49175, is used across multiple vehicle platforms including Ford Escape, Mazda 6, and Mercury Mariner applications.

Key Features

• 12-volt ignition coil for distributorless ignition systems
• COP (Coil on Plug) design for direct spark delivery
• Blade terminal style with 2 terminals
• Female connector gender and male terminal gender
• Oil-filled: No
• Mounting bracket not included
• OE-style construction for consistent fit and function

Detailed Product Description

NGK 49175 is a coil-on-plug ignition coil designed for vehicles using direct ignition rather than a distributor-based setup. Its COP configuration places the coil directly over the spark plug, helping maintain stable ignition output in applications such as 2001-2008 Ford Escape, 2003-2008 Mazda 6, and 2005-2008 Mercury Mariner. This part number also appears in fitment for Ford Five Hundred, Ford Freestyle, Mercury Montego, Mazda MPV, Mazda Tribute, Ford Taurus, and Mercury Sable applications.

Built to OE-level standards, this ignition coil is intended for drivers and technicians replacing a failed coil due to misfire, rough idle, or ignition performance loss. This part cross-references DENSO Auto Parts (e.g., 673-6005) for the same application.

What It Is Used For

• Engine misfire diagnosis tied to weak or failed ignition output
• Rough idle caused by inconsistent spark delivery
• Hard starting related to ignition coil failure
• Loss of acceleration or hesitation under load
• Check engine light conditions associated with ignition system faults

Installation Notes and Tips

Verify the connector style, terminal count, and COP configuration before installation. This part uses a female connector with blade terminals and is specified for distributorless ignition systems. Confirm vehicle-specific fitment by year, make, and model before replacing the coil, especially on Ford Escape, Mazda 6, and Mercury Mariner applications. Inspect spark plugs and related ignition components during service to help prevent repeat coil failure.
