hello sir hans, actually same lang din yung sa pagddrive ko, ,mas mababaw din yung tapak ko sa gas pedal nung platinum spark plugs pa gamit ko. Nung pinalitan ko ng standard sparkplugs (NGK DCPR7EA-9) bumalik sa dati yung fuel consumption. Actually sir, kung hindi lang tlga malakas sa gas, I'll stick with the platinum alloy spark plugs. Pero after a week tlga ramdam ko na yung bigat ng fuel consumption. Siguro ok lang yung platinum SP if you want a faster and more powerful avanza engine. But mas important sakin yung fuel consumption lalo na mahal gas ngayon
