Planning to change the spark plugs in the '99 Camry. Thought it would be straightforward... the manual gave Denso PK20TR11 and NGK BK-(it's- really-long) as approved replacement plugs.
Called one auto supply store (on the way home from work-really convenient) who told me the spark plug naming convention changed last year, and the NGK plugs compatible with the car are $14 or so each.
Called another auto supply store - they gave me a choice of two possible NGK ones: the expensive one, some $14 or so (it's laser- etched... even the guy didn't know what that signified) and one for about $3 each. Both NGK, platinum.
Called the dealer and they only sell Denso, some $13 each or so. Toyota part 90919-01194.
Would I be making a mistake going for the $3 NGK ones?
