Denso K20HR-U11, July 6, 2013
Keith Sheets (Oklahoma)
These were purchased for use in a 2007 FJ Cruiser. They work just fine. Lower rating is pointed at Amazon. I ordered six, but one was cracked (not broken) when I received it. Since it wasn't broken, it took a lot of troubleshooting to figure out why the FJ was running so poorly after getting the new plugs. Once I figured out which cylinder was acting up and discovered the cracked insulator, I replaced the cracked one and the FJ is running like a new one. FYI - the FJ maintenance schedule calls for new plugs every 30K miles. Mine had over 80K on them when I replaced them for the first time, but still ran fine. Replacing the plugs did make a noticeable difference in power and fuel mileage.

OEM part. So it fits perfectly and restores engine power, and gas mileage. No need to gap. Easy to install.

Perfect!, October 6, 2013
