Anybody here who would like to share anything about modified spark plugs? i received this message from my cellfon many times in the past. A certain Engr. Garong claims that it improves power and saves fuel. Ito ba yung binubutasan ng special tool ung tip ng spark plug? I need to be enlightened in this offer.
If he claims that his method works well by improving power and fuel efficiency, how come makers of spark plugs don't market it?

previously also on my vitara which i sold already. the car is very responsive rather than bosch sparkplugs. but i would like to try the torquemaster...
I do believe it works, a freind of mine has tried this for his honda accord and toyota corona and claimed it does improve power and his modified stock spark plugs life longer, re fuel consumption though he has not actually monitored. he claimed that he got this idea from toyota casa...some guys there do recommend this.
