I went for a tune up and the guy said that 3 out of 4 plugs are almost gone. this was the second time i bought and they are gone now,
i think they are of low quality NGK or i dont know whats the problem with them.
if i go for Bosch 4tip plugs, would that compromise on efficiency?
plus, i might have to change their wires too, my friend is having something similar to this, written TRD on it:
<strong>how about i go for these with 4 tip plugs? <strong>
