    if you do tighten it by hand, how can you know na tama na yung pa-torque na dapat ilagay according to the manual??
    anyways, i want to give iridiums a shot after i read this page http://www.autoindustriya.com/testdr...oiridium.shtml
    sana totoo ngang i-improve ang fuel economy.

    YESSS

    pwede na nga lang hand tight for spark plug

    feel mo na lang ng kamay mo ang tamang higpit ..basta wag lang din sobra at wag din maluwag ...di naman kailangan masyado higpit kasi wala naman movable parts jan or na ngangailangan ng balance or equal tightening Like camshaft,gears,drive shaft.IMHO

    pwede ata!!! Iridiums ang OEM plugs na nakasalpak sa Rav4. subukan ko mamyang gabi.

    though sabi sa akin nung taga Denso... kapag yung aftermarket Iridiums (for cars not equipped with OEM Iridium plugs) nila is only good for 20K km. yung OEM Iridiums ay good naman for 100K km.

    pero kung 20K km lang... hindi sulit. eh magkano lang ang ordinary spark plug? less than a 100 each.

    IMO - this test in inconclusive since the driving style & traffic conditions between the two test drive runs are different. heck, my fuel consumption averages around 8.5km/L, but it can swing from 7.5 to 9 depending on the traffic condition during those times.
