Definitely worth it to buy, my husband bought boshe I think its called but the lower end of boshe and it kept causing our truck to missfire. Both brand new, but Denso did its job. No more deceleration on the RPM when its idling.

Ordered these for 3nd gen Taco. Since new the truck stalled, hesitated, almost dies during acceleration. Throttle response terrible. Fine once achieve hi-way speeds. Changed coils, throttle body, exhaust.....etc. nothing helped. Pulled the OEM plugs and tested, 3.11k-4.10k ohms. Found 2 of the Denso IKBH20TT plugs bad 4.11k-4.12k ohms. Return and replaced, these 5.20k-5.50k ohms. Kept the gap at 0.04 since a larger gap produce more hp ?? Throttle response great, smooth accel, engine ran better, slight improved hp/mpg. Amazing never thought spark plugs would make such a difference. Convinced OEM pugs are junk.
