I'm bout to buy some new spark plugs and I wasn't sure, since theres one thats like primary and one thats secondary, does it mater which one goes where? Or are they the same spark plug so it don't matter which one goes where? BTW, if it does matter, can you tell me the order? I think Primary is on top but I could be wrong

 

their are trailing plugs and leading plugs. take them out one by one and replace it. the plugs should have a T for trailing and L for leading. I think the leading are on the bottom and the trailing is on the top

 

if u look rite on the houseing of the motor it says...T and L, make sure u get the rite plugs, they are different than piston plugs.

 

you need 2 sets of plugs

I cant remember off the top of my head which one is leading and which is trailing but yea. Easy way to remember is T=top and L=lower. T1 is the front front and L1 is the front rotor and T2 and L2 are for the rear. Make sure your spark plug wires will be on the right spark plug and coils. You can take each one off at a time so you dont get them confused but the coils are also labeled.
