Rx7-AIII

Hi
I have been sold a set of spark plugs for my FD. Plugs are NGK BR10EIX stock no 6801. I wanted heat NGK range 10 racing plugs. These plugs dont look like rotary plugs to me. Seller tells me they are fine but I have doubts. Has anyone used these or know for definite what they are for? I don't much fancy another rebuild!
Thanks

Why 10s?. If so, get the racing plugs- 10.5 heat
range. Number is r6725-105. I run up to 22psi
on bur9eq[stock trailings] all the way around
with no probs. I will be running 25+psi next
year so the 10.5 is needed.

I think I read in one of the other spark plug threads that someone had trouble with the EIX's.

I have 10.5's. I wanted to run 10.5 lead and 10 trail. I was expecting to receive 10 heat range racing plugs. I just cant find out what these EIX's are really for.

Those are for Rotary engines the BR10EIX are the "Iridium" version of the spark plug.

They're probably also a short-bodied plug that will be a bit more difficult to get threadded into the rotor housing. Also, they're a non-resistor plug; beware trigger noise.

I've used the BR10EIX and they seem fine to me.
I think there just as good as my B10EGV's but will probably last a little longer because their iridium.

Since you already have them just use them. You shouldn't have any problems.
