ThunderSpark 921-92345 ignition coil for the 2018-2024 Lexus IS300 4-cylinder 2.0L and other vehicles sends a high-voltage pulse to a spark plug. It gets its signal from the distributor or engine control computer at the time combustion needs it.
- ThunderSpark ignition coils use high-dielectric epoxy and copper windings
- Heat-resistant housing for engine-bay temperatures and electrical demands
- 12-volt electronic coil that needs no external resistor
- Four blade terminals with a female connector
Quick facts
- Part: ThunderSpark 921-92345 ignition coil
- Fits: 2018-2024 Lexus IS300 4-cylinder 2.0L and other vehicles
A failing coil can show up as a misfire, a rough idle or hesitation under load. A misfire alone does not prove the coil is at fault, since a worn spark plug can cause one too. These engines take four coils, one per cylinder.
Fits
Among the vehicles it fits are the 2018-2024 Lexus IS300 4-cylinder 2.0L, the 2018-2024 Lexus RC300 4-cylinder 2.0L and the 2018-2021 Lexus NX300 4-cylinder 2.0L, and it is an OE replacement for them. Open the "Vehicles it fits" section to check your exact model and engine.
