Hi any one run long reach plugs if so withc ones, any advantages? or disadvantages? Yes I did a search and read evry thing that was on the site about spark plugs Rag's

they run great if you need them they somtimes run cleaner,,,just use the same heat range

Are you talking projected tip plugs? If so I believe these are not recommended in blower or nitrous applications. If the motor is NA the projected tip plugs work great is what I hear. Anyone run proected tip plugs in blower motors?

I do understand the benfets of the projected tip I think but when looking for plugs I found that there is diffrent reach lenths also. Like 0.375, 0.460, 0.708, and 0.750. some listings also call out 3/4 reach? Looking to eat up a couple of cc's if I can on a close to stock NA motor. Rag's

The AC Delco MR43TS is a standard reach plug and the MR43LTS is a long reach plug. I used the LTS in my HP500 carb and they worked great.

Hope this helps...
