Review on High-Quality DRIVESTAR Ignition Coil Pack Set for Toyota 4Runner, Land Cruiser, Sequoia, Tundra 4.7L and Lexus GS430, LS430, SC430, GX470, LX470 4.3L, 4.7L, 5.7L by Trevor Blazis

A coil failed after 8 months. Went to the warranty website. No Answer. I tried calling the service number, no one answers the phone. Spark plugs were changed when changing coils. I used cheap casters before. They have an average failure rate of 20%. The last install I did was on a Ford V8, two of which failed in the first 6 months. Others have driven 100,000 miles or more. I ordered here because they had 1 year warranty. Apparently not. Save your old coils, you will need them. I have one in my glove box with the outlet needed to replace it.
