Great plugs
The owner of the vehicle said that she has experienced much better power and pickup in her Scion XA than she had before. She stated that she had to "punch the gas" in order to get the car to take off from a stop (automatic transmission) prior to the spark plug replacement. After replacing the spark plugs, the vehicle accelerates smoothly from a stop. The owner also says that the vehicle shifts more smoothly and appropriately (for the engine speed) than it did prior to installing these plugs.

Won't purchase again.
Installed in my 2006 Ford Ranger at about 100,000 miles. I've noticed difficult starting for past month. On 7-10-18 I replaced the Densos with NGK V Power plugs. When I removed the Densos I noticed 2 plugs showing normal wear and measured .047" gap but 2 showed severely worn center electrodes and measured .076" and .079" gaps. The mileage is 144,071 on my odometer.
