  • Perfect replacement plugs!
My 2010 Silverado 1500 5.3L with 186,000 miles was running rough while idling so I decided to change my plugs. It was no easy feat for a short girl. But it was well worth it. These NGK plugs are a trucks life saver. The quality is noticeable right out of the box. The were really easy to install, the threads were smooth going in. Some of the gaps were off so I readjusted. These are ideal replacement plugs and cheaper on Amazon vs the parts store. My truck is idling and driving better. I'm really happy with my purchase and I highly recommend these! ... show more

  • Reliable plugs at a good price
I've never had an issue with NGK plugs and this set didn't disappoint. Went into a 13 GMC sierra with the 5.3 engine. The same plug is almost twice the price at the local auto parts stores.
