Champion 19273 Spark Plug

Champion Iridium Spark Plug

Champion Iridium spark plug 19273 is a standard replacement plug built with a fine-wire iridium center electrode and a platinum ground electrode for sharp spark focus. It is engineered for direct service on select Ford applications, including Fiesta, Escape, Transit Connect, and Fusion models.

Key Features

• Fine-wire iridium center electrode for precise spark delivery.
• Platinum ground electrode for stable ignition performance.
• Standard replacement design for routine service work.
• Pre-gapped to 0.031 in. for installation convenience.
• Tapered seat, resistor design, and 14 mm thread diameter.
• Champion Iridium construction for consistent secondary ignition service.

Detailed Description

Champion 19273 uses an iridium center electrode paired with a platinum ground electrode to concentrate the spark and support efficient combustion. The J-gap design, 0.031 in. pre-gap, and resistor construction make it a practical OE-style service part for compatible Ford ignition systems. This spark plug cross-references RES6ZWMPB for the same application.

The Champion Iridium line focuses on precise ignition characteristics and durable electrode materials. For drivers servicing Ford Fiesta, Ford Escape, Ford Transit Connect, or Ford Fusion applications, this plug provides a direct replacement option that matches the specified heat range, reach, and tapered seat requirements.

What It Helps Solve

• Misfires caused by worn or eroded spark plug electrodes.
• Hard starting related to weak ignition spark.
• Rough idle from inconsistent combustion.
• Reduced throttle response from degraded plug performance.
• Service replacement needs for specified Ford ignition applications.

Installation Notes

Verify the tapered seat, 14 mm thread diameter, 1.000 in. reach, and 0.031 in. pre-gap before installation. Confirm the plug specification against the vehicle service information for the exact Ford Fiesta, Ford Escape, Ford Transit Connect, or Ford Fusion application. Use proper spark plug handling and torque procedures during service.

Quality Assurance

Champion Iridium uses fine-wire iridium and platinum electrode materials to support consistent spark focus and dependable ignition service. Part number 19273 is built as a standard replacement spark plug for the listed applications.
