[QUOTE="Stroked out, post: 1320497, member: 30217"] The 542 helped my truck run smoothly, changed them with less than 2k on the clock. On my second set (the first set was fine) just checking the burn. My first set I gapped to 25 and the second I left alone at 28. The stock plugs were just to jumpy for me. Btw my tuner suggested this change. [/QUOTE]
