Comments about NGK Laser Iridium Spark Plug (ILFR6A):

Advanced had the plugs for $7.00 less than dealer and 2.00 less than everyone else.. Still spending [$] on a single plugs is outrageous let alone needing 16 for my car... By no means is it advances fault as they offered lowest price out there!! Thanks will order from again
