Part Details

  • Set Quantity:   3 Piece

The ignition coil is a crucial part of your ignition system. It's function is to convert the 12 volt power of your vehicle's electrical system in to 35,000 or more volts. This produces a high intensity spark at the spark plug which then ignites the fuel in the cylinder. Coils in general will wear out over time. This will cause a misfire condition.

So good, so far...
My first time with ignition work with a Japanese car. I was un-familiar with the process, but when I finally got down to the coils, they were the exact right fit and went in easily. I must admit I was a little surprised that the car started right up and is running fine. After 3 months products are still working perfectly. I would recommend and will buy more parts from 1AAuto.

Great parts
Arrived earlier than original estimates. Put in both my kids IS 300 with 200k miles along with wires and plugs. Cars picked up thirty HP, lost the accelerator hesitation and run great. No codes. Bolted right in. Great parts

So this was my last stop before going full OEM / top brand to get my 2003 lexus gs 300 working again. I had an error code P0301. Researched and found this to be possible cause.. granted this was after i replaced my valve cover seals and spark plugs to brand new (iridium ix). Changed my spark plug wires next, connectors, and coil packs being the last! Knew it was coil pack because the cheaper replacement i got actually made it worse than the original. Replaced-- WORKS GREAT.
