Review on 🔥 NGK Laser Iridium Spark Plugs (Set of 4) IFR5T11 - Brand New by David Carmody

Bought for my 2009 Toyota Prius. If you're changing spark plugs yourself, watch a few YouTube videos before you start. You have to remove a few items before you get to the stubs, not the main items. I forgot to reconnect the wiring harness and the check engine light came on. After reconnecting the wiring harness, I turned off the check engine light by going into the trunk and disconnecting the positive cable from the battery for 15 seconds. The check engine light has gone out. It took about 30 minutes from start to finish. The Toyota dealership charged over $300 to replace my spark plugs
