So far so good, these are NOT pre gapped, so make sure you gap them to your proper spec, but otherwise perfect for the tune on my Focus ST.

Engine in my 2015 Mustang GT feels a little snappier, less knock under acceleration after installing the GT350 throttle body and cold air intake.

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!
