• NGK stock number 48583; part number U4024

Detailed Description

NGK ignition coils are manufactured to support OE-level fit and performance expectations, using controlled production and validation processes to help maintain consistent spark delivery. This coil is part of NGK’s COP (Waste Spark) Ignition Coil line, a product line focused on distributorless ignition service for vehicles that rely on coil-based spark control rather than a distributor.

Part Number 48583 cross-references Standard Ignition UF-155 and Delphi GN10218 for the same application. It is listed for 1996-2001 Lexus ES300, 1996-2001 Toyota Camry, 1996-1999 Toyota Avalon, 1998-2000 Toyota Sienna, and 1999-2003 Toyota Solara. If you are replacing a Toyota Camry ignition coil or servicing a Lexus ES300 ignition coil, this NGK unit matches the documented fitment data.

What This Coil Helps Address

• Engine misfire caused by weak or inconsistent ignition output
• Hard starting related to ignition coil failure
• Rough idle from degraded spark delivery
• Loss of power under load due to ignition breakdown
• Check engine light conditions tied to ignition coil faults

Installation Notes and Tips

Verify the connector style, terminal layout, and OE part number before installation. This coil uses a 12-volt distributorless design with a blade terminal arrangement, so matching the original electrical connection is important for proper operation. Confirm vehicle-specific fitment for your Toyota Camry, Lexus ES300, Avalon, Sienna, or Solara before replacement.

Inspect the ignition connector, wiring, and surrounding components for heat damage, corrosion, or carbon tracking during service. Replacing a failed coil without checking related ignition components can leave underlying issues unresolved.

Quality Assurance

NGK manufactures ignition coils to meet or exceed OE standards and validates designs in an ISO 17025 accredited test lab. The brand’s long history in ignition components and broad OE coverage support confident replacement selection for select Toyota and Lexus applications.
