Product Details

The NGK Coil Near Plug Ignition Coil line is built around OE-level fit, form, and function for modern ignition systems. NGK applies more than 80 years of automotive experience to its ignition products, with manufacturing and testing processes focused on durability and operational consistency. Part number 48933 is part of that coil near plug lineup and is used on a broad range of GM trucks, SUVs, performance cars, and vans.

This part cross-references Delphi GN10165 and Standard Ignition UF-414 for the same application. Search terms such as NGK 48933 ignition coil, coil near plug ignition coil for Chevrolet Silverado 2500 HD, and ignition coil for GMC Yukon XL 1500 reflect common fitment-based searches for this part.

Common Issues This Part Addresses

• Engine misfire caused by weak or inconsistent spark output
• Rough idle or hesitation under acceleration
• Hard starting related to ignition coil failure
• Check engine light triggered by ignition system faults
• Loss of power from degraded coil performance

Installation Notes

Verify the ignition coil shape before ordering. Several listed applications require a round ignition coil for proper fitment, and some 2007 Silverado and Sierra applications note a new body style round-type design. Confirm connector style, terminal layout, and vehicle year before installation. This part is listed for distributorless ignition systems and a COP configuration, so it should be matched to the original coil design on the vehicle.
