so i bought my 7 off of this guy in windsor a few months back and he didnt know **** all about rotaries , but anyways i drove it around and everything and it seemed alright he gives me a whole box full of parts and other crap ( even his house keys ). i go to check the spark plugs today and there the same number ? and look the same ? my car is not working now and i was wondering if this could cause a problem ? im fixing my 7 slowly and would like to know these little things lol

 

bur7eq and bur9eq are the stock Ngk Numbers that you need for leading and trailing
..You will find that they are NOT cheap.The Best bet Going is to get them off of Ebay.(,.I got sets for 25 USD.,.that beats 90Cdn at a Partsource!)

 

BUR7EQ - 6.80 USD

BUR9EQ - 6.80 USD

2(6.80) + 2(6.80) = 27.20 USD

27.20 USD = 28.70 CAD

I don't think it would cause the car to not run, though it's not the idea setup. They will look the same as the only difference between the factory reccomended plugs is the heat range. I've ran all trailing plugs(bur9eq) before with no problem. I wouln't run all leading any longer than I had to the bur7eq would be too hot a heat range for the trailings.

 

thanks for all the info , im glad i know now .

 

When you pull the spark plug wire boots off, you'll see the 7eq and 9eq's are also different visually. The insulator portion has blue bands around it. I think there's another difference, but can't remember.

 

i felt kind of stupid asking this qeustion but i had to ask lol . and does anyone know if mazda still sells plugs ?

 

You dont need to go through a stealership. Go to your local auto parts store and ask them to order the specific plugs you need. Friend of mine did this and it only cost 26bux for a set of four.

 

Whoops, I forgot about the blue bands when I posted last night. I was thinking mostly about looking at the electrodes. They also have L or T under the part number on the plug.
