Detailed Description

NGK 48746 is part of the NGK COP Ignition Coil line, a product line focused on coil-on-plug ignition service for late-model domestic and import vehicles. This ignition coil uses a distributorless, coil-on-plug design with a 12-volt electrical setup, blade terminals, and a female connector interface. The part number 48746 appears in NGK documentation as stock number 48746 and part number U5203.

For Suzuki SX4 and Suzuki Grand Vitara applications, this coil is intended to restore stable ignition output and consistent spark delivery when the original coil is worn or failing. The NGK ignition coil 48746 is manufactured and tested under controlled conditions to support OE-style fit and function.

This part cross-references Beck/Arnley 178-8332 and Standard Ignition UF-562 for the same application.

What It Is Used For

• Misfire diagnosis tied to weak ignition output
• Rough idle caused by inconsistent spark delivery
• Hard starting related to coil degradation
• Loss of engine smoothness under load
• Check engine light concerns linked to ignition faults

Installation Notes and Tips

Verify connector style, terminal layout, and engine application before installation. This coil uses a 3-terminal blade connection and a COP configuration, so matching the original electrical interface is important. Inspect the spark plug and related ignition components during service to avoid repeat failures.
