I wanted to know where the trailing and leading plugs go, as far as which is on top and on bottom. THanks

 

I tihnk its trailing in the top, and leading in the bottom. T for trailing, T for top, L for leading, L for lower.

Wait for sumone to confirm this before u go shoving them in though. I'm gettin old and not rembering things as well anymore.

 

The lower leading plugs should have two blue rings, if I remember them correctly.

 

Confirmed. If you got the plugs from Mazda the box has a pic and if you are installing these from the bottom you can see the T and L on the housing.

 

I just looked at some trailing plugs and they had two rings. They also have the BUR-9EQP and a T on them, so it should be clear which plugs are which.

T = Trailing = Top
L = Leading = Lower

-Max

 

If u want to just forget about all that run all 9's.

 

Speaking of spark plug do you have to take the throttle out in order to replace the spark plug?

 

I jsut go from the bottom fo the car

 

throttle body isn't any where near the spark plugs...?

 

I say run all 9's or higher if you can find them like nameless said. Also, its really not hard to take out sparkplugs, in the last 4 days, I must have taken them all on and off about 20-30 times (and this was from above). Its even easier from below. The only thing is that 94 auto FD's seem to have a plastic box down there as well as extra lines of some sort that seem to block your wrench/hand. These are much harder to change the plugs out of, even from below.

Good luck
