NGK 48930 Ignition Coil

NGK COP Ignition Coil for Toyota and Lexus

The NGK COP (Pencil Type) Ignition Coil is a distributorless ignition coil built for direct replacement on select Toyota and Lexus applications. It is engineered to meet or exceed OE standards for durability and consistent ignition performance, making it a practical choice for restoring reliable spark output.

NGK’s COP ignition coil line is backed by the brand’s long OE legacy and extensive testing in an ISO 17025 accredited lab. The result is a pencil-style coil designed for late-model domestic and import vehicles, including Toyota Highlander, Camry, Sienna, Solara, and Lexus ES330, RX330, and RX400h applications.

Detailed Description

This NGK ignition coil, part number 48930, is intended for vehicles using a coil-on-plug pencil-style ignition setup. It supports consistent voltage delivery to the spark plug and is built for direct-fit service on select Toyota and Lexus models. If you are replacing a failing ignition coil on a 2004-2010 Toyota Highlander, 2004-2006 Toyota Camry, or 2004-2006 Lexus RX330, this coil provides the correct COP configuration for the listed applications.

NGK’s manufacturing approach emphasizes OE-level durability and performance, with product development and validation performed under controlled test conditions. This part cross-references Standard Ignition UF-430 and UF-506 for the same application. NGK 48930 is also referenced under part number U5146.

What It Helps Address

• Engine misfire caused by a weak or failing ignition coil
• Rough idle from inconsistent spark delivery
• Hard starting related to ignition output loss
• Loss of acceleration response from intermittent coil performance
• Check engine light conditions tied to ignition coil faults

Installation Notes and Tips

Verify the connector style, terminal layout, and COP pencil-type design before installation. This coil uses a female connector and blade terminals, so matching the original electrical connection is important for proper fitment. Confirm vehicle application by year, make, and model before replacing the original coil on Toyota Highlander, Camry, Sienna, Solara, or Lexus ES330, RX330, and RX400h models.

For best results, inspect the spark plug and related ignition components during service. A worn plug or damaged connector can affect coil performance even when the replacement coil is correct.

Quality Assurance

NGK manufactures ignition coils to meet or exceed OE standards and validates designs through rigorous testing in an ISO 17025 accredited laboratory. The brand’s long-standing OE experience and broad vehicle coverage support confident installation on the listed Toyota and Lexus applications.
