NGK Laser Iridium Spark LZFR6AI Review

2006 Mitsubishi Galant stuttered at low idle. Wife said it needs renovation. I said that they basically just replace the spark plugs, charge hourly rates and significantly increase the price of the spark plugs. I watched a video on YouTube (this needs to be done before you do it yourself). This model is stupidly easy to make, others not so much. Look before you jump. See what tools you need. But these spark plugs are OEM replacement parts, cheaper than parts stores. Now the car drives better.
