Ok i bought 4 new plugs (made sure that they were for my pro) bought antisieze and a socket wrench and finally I bought a gapping tool. Here lies the problem, how do I use the gapping tool? What exactly does it measure the gap of? Thanks a lot!

 

First, you need your owners manual, in which it will tell you how big the gap is. Your gap tool should be either metric or standard, an since the car is Japanese you will need to use the metric side. You use by sliding the tool in the spark plug's gap, and the measure will read you a result. If it too small, force the gap to slide further (does not require a lot of power so be careful) until the gap is right. If it is too big, you will need to SLIGHTLY tap it on a hard surface. If you tap it too hard, the spark will not work properly.

 

ahh yess! Actually i figured it out, changed all four of em and it runs smoother now. I would have bought new wires but my current ones are in pretty good condition, so its all cool.
