So is the SP580 an improved spark plug? According to rock auto it is a "replacement" for sp534. Just wondering if there is actually a difference between the two.
 
Yeah, the SP528 insulators had a habit of cracking.  Thankfully no issues with the SP534 forward.
 
Is 0.032” now the recommended gap for stock application on 2013? I have the new SP580 plugs arriving tomorrow. :)
