## Description

Genuine 8 pack NGK Iridium IX 6510 Spark Plug

Review: Great plugs when needing a colder option - Engine in my 2015 Mustang GT feels a little snappier, less knock under acceleration after installing the GT350 throttle body and cold air intake.
Review: Perfect for 2018 suburban - Works perfectly for my 2018 suburban. It was recommended I use these since they run a bit cooler...I have performance headers, a tune, and a cat back installed. So far so good!
