yes that is the correct model number if your looking for the NGK Iridium IX Plugs...i have used them and had great results with these...the whole number is NGK #5464 BKR5EIX-11 but i went one step colder so you can get the "6" heat range if you want, dont forget to get 12 of them...it's recommended gap is .044" but i went with .039" with a torque of 21 ft/lbs.
