10* plugs with resistor......any?
looking for a 10 degree spark plug with resistors. i have only found the 10eix plugs which are iridiums and not good for the rotary. is there any plug made that is 10 degree with say a copper or platinum center? any imput appreciated.

The NGK R6725-xxx and R7420-xxx are the only plugs NGK makes in the proper reach (.846", same as stock), are resistor plugs, and are offered in the 10+ heat range. The R6725 and the R7420 are the same plug with the difference being that the R6725 is a platinum plug and the R7420 is iridium. The R7420 is apparently the same plug as the Greddy Race Plug.
I've used the EIX with good results as well as the EGV (non-resistor) with good results. However, both of those plugs only have a .750" reach so the tip is retracted around .010". Does that matter and if so how much and in what circumstance?

Good news to whoever wants the R7420's, they are trying to do a group buy at a killer price. ---> https://www.rx7club.com/jkl-engineering-271/gb-ngk-iridium-racing-plugs-power-cable-racing-plug-wires-701009/

the correct resistor plugs can get quite pricey. i usually change my plugs 3-4 times througout the summer. i have currently been using ngk R5671A-10. very similar to the B10EGV but they cost half the price, and i have had great luck with them. i found them years ago by another member who swore by them. they are also a 5/8" socket size so no need for a special socket.
** how many have been running non resistor plugs with hks twin powers? the only reason i ever think about getting resistor plugs is to keep from hurting the hks box.
