    Comments about Denso PT20TT Platinum TT Spark Plug:

    When it comes to ignition, and electrical parts, Made in Japan For The Win!!! For [$] (sale [$]) each + 90 day warranty there's nothing to lose. Just replaced my Motorcraft Platinum Plugs to Denso TT Plugs on 1994 ford Ranger 2.3L and wow! Noticeable gas mileage increase, plus super smooth acceleration...
