quick spark plug ?
 

hey what are the codes on the sides of our spark plugs? trailing and leading. and how does the order go?

T-T
L-L or the other way around? ok thanks

Gabe

L is leading (lower)

T is for trailing (top)


L-lower
T-top

The spark plugs are marked just the the engine block is with T ands L's also the ignition coils are all marked as well with T1 or 2 and L1 or 2 so you can always know where the spark wires go, get a flash light and look down there, hope this is of help otherwise oh well

thats cool with the t for top and L for lower. but about the codes on the side are they

T-BUR9EQ
L-BUR7EQ

86-92 All
........City(hot) --------HWY (cold)

L -----BUR6EQ --------BUR7EQ
T -----BUR8EQ --------BUR9EQ

86-95 Platinum

L------BUR6EQP-------BUR7EQP
T------ BUR8EQP -----BUR9EQP

I believe the plugs are also marked "T" or "L", in addition to the number.

That is correct.
