Question 86 rx7 spark plugs

Hey folks,

Decided to treat my baby with some new plugs, the old ones didnt look too bad upon removal, but since this was a used car and not knowing when they were last changed i did. I went to my local mazda dealer and gave them my information and they sold me 4plugs all the same(25$/per). Now i've read alot recently and see alot of reference to different plugs for the leading and trailing plugs, so whats correct? The car has the 13b with injection. Oh and btw, if you saw my vid, i mentioned an oil/coolant leak, turns out its a tranfluid/coolant leak, hopefully its just a seal. Glad its not from the motor tho.

Only plugs I would recommend for the Rotary is NGK. The leading & trailing plugs are different. BUR7EQ (2) & BUR9EQ (2).
