hey everyone, im in the process of servicing my recently imported 32.
upon removing the coils and spark plugs, ive discovered that the (platinum) plugs have been marked with texta on the side of the porcelain in line with the electrode arm.
i also noticed when removing them that all these marks were pointing dead straight toward the front of the engine - obviously aligning the electrodes foward..
ive heard rumors that this makes the engine more efficient, and more powerful etc etc.. now is it worth my while to do the same thing when i install new ones? there is obviously no harm in doing it, but does it actually make a difference is what im curious to find out.
next question is, if i am to do this, how do i align them while keeping the correct torqe on them without over tightening and under tightenting to keep the electrode aligned?
