Original Review: Immediately noticed a performance increase after installing these plugs in my 3rd Gen Tacoma. Not disappointed! ## 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.
