## Description

Denso Spark Plug Iridium TT - 4705

Review: Amazing (3.5 3nd gen Tacoma) - 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.
Review: Didn't blow up the engine. - I used these to replace plugs on an 18 sienna. I noticed after I received them that it was not the OEM part number but after a bit more digging found that they still would fit. I'll tag on the same complaint with the packaging for these. They were in a regular paper package and inside small little cardboard boxes. Would be easy to damage them or mess up the gap. But in my case they all turned out fine. I still had to adjust the gap slightly. I know all the packages say not to but I've had no problems as long as it's just a slight adjustment. I feel like the engine ran quieter and had a bit more power after replacement. I'll likely use these again when I get to the change interval later.
