NGK RC-TE79 6404 Spark Plug Wire Set Lexus GS300 IS300 SC300 Toyota Supra 3.0L

Vehicle Fitment

• 1998-2005 Lexus GS300 (Base, 3.0L I6 2JZ-GE, RWD)
• 2001-2005 Lexus IS300 (Base, 3.0L I6 2JZ-GE, RWD)
• 1998-2000 Lexus SC300 (Base, 3.0L I6 2JZ-GE, RWD)
• 1998 Toyota Supra (Base, 3.0L I6 2JZ-GE N/A, RWD)

Fitment Notes

• Fits the naturally aspirated 2JZ-GE inline-6 engine only - does NOT fit the twin-turbocharged 2JZ-GTE (Toyota Supra Twin Turbo), which uses a direct coil-on-plug ignition system and requires no plug wires.
• Toyota Supra fitment is limited to the 1998 model year Base (non-turbo) only.
• This is a 3-wire set (one per coil pack, covering two cylinders each on the 6-cylinder 2JZ-GE waste spark ignition system) - not a traditional 6-wire set.
• Replaces Toyota OEM part numbers 90919-15568, 90919-15569, and 90919-15570.
• Wire set is vehicle-specific - not universal fit. Wires are pre-terminated to OEM lengths.

Features

• High-temperature silicone outer jacket withstands underhood temperatures up to 250°C (482°F) without cracking or degrading.
• Variable pitch magnetic core winding suppresses EMI/RFI electrical interference across a wide frequency range, protecting vehicle electronics and sensors.
• Ultra-low resistance mag core delivers significantly less resistance than conventional carbon core wires for a stronger, more consistent spark.
• High-density fiberglass braiding over EPDM/silicone inner insulation provides superior dielectric strength and tensile resistance against pull-out damage.
• Stainless steel terminal ends with silicone-sealed spark plug boots provide a watertight, corrosion-resistant connection at each coil and plug.
• Custom application-specific terminal boots deliver exact OEM fit - not generic universal boots.
• 5mm wire diameter - purpose-built for the 2JZ-GE's compact engine bay and coil pack layout.
• Backed by NGK's Lifetime Warranty.

Product Description

The NGK RC-TE79 (Stock No. 6404) is a direct-fit spark plug wire set engineered for Toyota's naturally aspirated 2JZ-GE inline-6 engine as found in the 1998-2005 Lexus GS300, 2001-2005 IS300, 1998-2000 SC300, and 1998 Toyota Supra (Base/N/A). The 2JZ-GE uses a waste spark ignition system with three coil packs, each firing two cylinders - which is why this is a 3-wire set rather than the traditional 6 wires. The twin-turbocharged 2JZ-GTE in the Supra does NOT use plug wires (it has a coil-on-plug system), so verifying your engine before ordering is essential.

Constructed with a 5mm variable pitch magnetic core, blue silicone jacket, and application-specific boots pre-terminated to OEM lengths, the RC-TE79 installs without modification and restores factory ignition reliability on the 2JZ-GE. The magnetic core provides ultra-low resistance and effective EMI/RFI suppression, protecting the 2JZ's engine management and sensor systems from ignition-generated interference. Backed by NGK's Lifetime Warranty and replacing Toyota OEM part numbers 90919-15568/69/70, this is the definitive wire set for the 2JZ-GE platform.
