where can I get NGK plugs for my 76 Cosmo engine that's in my Rx-7? The auto parts places around here have no idea... it's listed (part # 4121) (same as an Rx-4)

I have 82 Rx-7 plugs in it now (in it when I got it), and it just isn't idling right... think that may be the problem. It's got kind of a lobe type sound, if that makes any sense. Any good advice requested. Thanks.

the stock brxxxx14 are good for stock motor. For my streetport engines, I get the plugs (b8ev's to b10ev's) from the honda motorcycle dealer.

you might try Atkin's Rotary in Puyallup or that place over in Postfalls.

I'm ready to drop that engine in the RX-2 btw . . . drop me a line.

My '76 Cosmo with stock engine likes BR8EQ-14 plugs and DLIDFIS. That's the only combo that has worked on this engine so far. I have yet to install a relay, and it still runs great on the old stock key (ignition) switch wires.
