Review: 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: 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.

## Features

- IKBH20TT | Twin Tip Plug | Tightneing Torque (Nm): 22 | 3 - Earthed Electrode | Diameter (mm): 14 | Thread Length (mm): 26.5
- The Finest Twin Tip plug with improved acceletation, fuel economy and longevity compared to single tip plugs. The quenching effect has been decreased by forming the electrode into a double needle shape. As a result, the flame kernel rapidly develops and the engine’s power is drawn out to its maximum potential. DENSO IRIDIUM TT spark plugs have a φ0.4 mm iridium alloy center electrode and a 0.7 mm needle-type platinum alloy ground electrode.
- The iridium tip is mounted with an “All-around Laser Welding” method that insures high reliability even under the most severe driving conditions.
- Using DENSO’s exclusive iridium alloy having a very high melting point, the tip of the center electrode can be shaped very thin and fine, reducing spark voltage requirements and greatly improving ignitability.
- All specification types include an embedded, highly reliable, monolithic resistor to eliminate electoromagnetic noise interference from all kinds of electronic devices.

True Denso. They have worked great since I put them on my 07 IS250 in August 2024.
