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.

Used on my 2010 Tacoma v6, March 10, 2013
Gapped to .040 and installed on my 2010 Tacoma V6. Worked completely fine. The engine sounds a lot stronger when it starts now. I did this change at 37,000 miles, old plugs looked worn down with a gap of .049. These are OEM for tacomas on driver side while passenger side gets NGK's for some reason (or vice versa). I use these on all 6 and no issues.

Installed on my 05 Tacoma 4x4, 4.0 engine. Went with these due to the cost. My engine runs well and if they should fail b4 my next 30K miles, it'll be cheap to replace.
