im getting confused i need new spark plugs for my 1987 turbo FC and advance auto says that they are like 6.98 a piece but they have never said antyhing to me about buying leading or trailing plugs im confsued what should i be buying when i go up there tommorow please let me know before 2 because i get out of school then and i need to know before i go please someone let me know.

 

I just tell them the part numbers - NGK BUR7EQ and BUR9EQ. You need two of each.

 

thank you, you helped out alot i was about to buy 4 of the same.

 

And if that wasnt cool enough. Each plug has either an L or a T on it! Bet you cant figure out what THAT stands for!!

 

i didn't know im 17 never had a car really before just needed to know

 

Well, if you dont know, then you better figue it out especially if you are going to be installing the plugs yourself! And what does being 17 have anything to do with understanding what L and T mean? I cant stand when ppl use inexperience as an excuse for lack of thought.

T is for trailing, and L is for leading.
L goes in the bottom holes, and T goes in the top holes.
Make sure the wires get hooked up properly! There is L1, L2, T1, T2.

Yay!

 

alrite you dont have to be like snappy about it i think i coudl use age as an excuse because i wouldn't be looking into replacing parts until i could drive.. this would be my first car.. and ive never even seen a spark plug in real life so i probably would have realized this hwen i got there i was just hoping to get helped.

 

also, if that confuses you..

T could be Top
L could be Lower

thats what I use, just not to be confused.

 

thanks man. thats a good way of remembering.

 

Remember, a standard spark plug socket doesn't fit on these plugs. I do believe you will need a 17mm deep socket.

 

No, a regular 13/16 spark plug socket will work just fine.

 

Yep

 

this has to be the most helpful forum i have ever been on thank you guys so much even though some of the questions are stupid im glad people still help thanks alot guys i'll be going to pick up my spark plugs tommorow and hopefully my EGR will be here soon to get my baby running again.

 

Who is being snappy? I was trying to help...

 

not you J-rat.. sunshine

 

Every time I go to Kragan to buy spark plugs I have to tell them wich ones I need. They don't know squat about leading or trailing. Last time I just took the part number, it was much quiquer that way.....
