I recently had NGKs iridium go bad at 7k miles so I swapped out the plugs for new ones (I get them from UroTuning I doubt they’re fake FYI 😊) anywho, I replaced the plugs the misfiring went away fast forward 200 miles and it’s misfiring again. What could cause premature spark plug failure? I’m thinking it’s my ignition coil but could a coil ruin a plug and if yes would replacing the spark plug make the car run normal initially and eventually misfiring bc of the bad coil? THANK YOUUUUUU
