Show original supplier description
The Powerhouse Racing replacement coil harness serves as a reliable solution for aging or damaged factory ignition wiring in 1998-2005 Lexus GS300 models. Over time, original engine wiring harnesses can become brittle, cracked, or worn, leading to inconsistent electrical delivery that can cause persistent engine misfires. Designed specifically for the 2JZ-GE VVT-i engine, this replacement harness restores the integrity of the ignition system by providing fresh electrical connections to the coil packs. Replacing a faulty or corroded harness is an essential step when troubleshooting ignition-related performance issues on these platforms. It is compatible with 1993-2005 Lexus GS300 base models with 3.0L naturally aspirated engines, as well as 1991-2005 Toyota Aristo models equipped with the 3.0L twin-turbocharged engine.
