Review on πŸ”Œ Autolite XP5702 Iridium XP Spark Plug - 1 Pack (Automotive Replacement) by Mike Hernandez

Revainrating 3 out of 5

Good connector but don't use their gap recommendations

The .040" gap recommended by Autolite for my 2011 glk350 4matic is too big. This leads to rough idling, long run times when starting and hesitation when accelerating. If you have the same, your best bet is to stick to the Mercedes-Benz recommended clearance of 0.032-0.035 inches.

Pros
  • I'm looking forward to
Cons
  • I'm pissed
