What set of spark plugs are leading and which ones are trailing? I have to change the spark plugs on my car. Is top leading and bottom trailing or vise versa? Please help!

Thanks,

I believe the tops are leading and the bottom are trailing. (I'm pretty sure but someone please correct me if Im wrong)

 

On your old set of plugs, assuming they were NGKs, they should be marked T and L for trailing and leading. Also, trace your plug wires from the coil to the block. That'll tell you for sure.

 

yeah, look for T and L on the plugs, and match it with the T and L on the rotor housings (might bea bit dirty!)

 

k. i'll look for that. thanks guys =)

 

Never a problem

 

k. got um in. I guess I just couldn't think logically because I was freaking out that it wouldn't start, until I found out it was the spark plugs. it starts fine. thanks. =)

The car wouldn't start until you changed the plugs? Please, go on.

 

T- IS FOR TOP, AND TRAILING--- L- IS FOR LOWER AND LEADING SIMPLE HUH?

And if you have good eyes, on the coils and engine they are marked with those same letters. And if you are reaaalllyy lucky, like myself, the sparks plug wires are marked so accordingly also.

PEACE THE DOG
