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.
