BYD, Mazda, etc. Iridium Spark Plug BKR5EIX-11 5464 Economy Universal Type

For many 2000-and-later BYD, Mazda and other models, this universal KLP iridium spark plug (originally BKR5EIX-11/5464) uses iridium electrodes to improve ignition efficiency and extend life. Replacing the original part directly can effectively resolve starting difficulties, sluggish acceleration, rough idle, or increased fuel consumption, especially suitable for economical repairs. If cold-start performance is sluggish or acceleration is hesitant, the spark plug is aging and should be replaced.
