which plugs do you'll use for the trailing and leading? I'm trying to find some that are easier to get a hold of and dont want to charge an arm and a leg. right now i am using BUR7EQ L and BR9EQ-14 are there other plugs i can use in the trailing that are not $10 a pop?

 

Could be worse, you could be buying plugs for an RX-8. I use the 7/9 combo and get them cheaper than that from the dealer. You can get them from Mazdatrix cheaper than that I think. In fact Icemark use to sell them pretty cheap if I recall.

 

are those the right plugs though? is there another kind to use for the trailing?

 

really? cheaper on mazdatrix? oO I usually buy my spark plugs at a local Kragen for 6 bucks a pop...

 

Mazdatrix is not cheaper. but thats besides the point. Are those plugs the right plugs to be running? because right now i have BUR7EQ L and BUR9EQ T in the car is that alright? I wont mess up the housing or anything will I?

 

I generally just buy NGKs from Advanced... If want to see something funny, go to auto-zone and ask for some!

 

yeah $35 a pop F that been there done that no thanks i told the guy they were crazy

 

yeah for the same plugs at autozone i got cheaper by 75% cheaper at kragen

yeah your plugs are fine.

 

what i was worried about is that the upper plug did not or i thought it was not flat in the housing i thought it has a rounded edge like the S3 have i guess i was wrong.
