Use the same Denso K16PR-P11 plugs that were originally installed. Run an
Internet search - you can find 'em for $8 - $10 each. These Troops are
extremely sensitive to resistance variances from OEM plugs, and you risk the
dreaded CEL if you use anything else. AND, be very careful taking the old
ones out. At 100K, the threads have probably seized in that aluminum head
(assuming the plugs haven't been changed previously).
