I was going to replace my spark plugs and i was hoping to get an opnion on some good ones for the rotary.
thanks

 

unless you are modded to the point of needing RACE Plugs - Stock NGK Platinum -7& -9's (MAZDA OEM) are best. For a modded fd running 12+ psi boost you can run all -9's over 15psi I think RACE PLUGS are in order.

I think MAZDAFORMANCE has OEM plugs on sale @$8 or so each Check the web site

 

well just to let all of you know, kragens would be your best bet. here are the numbers that you need to look at when you talk to them. 5255 4764. the 5225 is the trailing plug with a heat range of 9 and the 4764 is the leading with a heat range of 7. the plugs are like 8.99/each. thats a damn good price. no shipping charges. you just have to get them special ordered. that is like two days. they can even get MSD wires but not for super cheap. 59.99 i think. aside from that i would not shop at an autoparts store and i work at one.
