Spark Plug Brand and Type?


Recommended Posts

Hey guys, What do most of you guys run for spark pkugs?? I did run NGK B8ES on my old motor. which was 130 PSI, Now i just built a 421 with 190 PSI. Im thinking the ones i have just arent cutting the mustard. Do any of your guys run like iridium's or anything??? .

I have heard bad things about getting creative with plug configurations. I run, and always will run NGK BR8ES. Iridiums I've heard have issues with losing electrodes. I may be totally wrong, but someone else will probably chime in with their own personal experiences.

Do you run alky or gas?

 

I use Race Gas. My old race sled use to run like shit on regular Br8es's, but then i found a Iridium for it and it never fouled again, it ran way better. Im just curious if theirs a nice race plug out their for banshee's.

Most sleds use a 9 heat range plug.. The SRX sleds came with the High Dollar plugs.

NGK BP8ES here.

 

SP

:headbang: Yep projected tip spark plug. That way it hangs down in the combustion chamber a little farther instead of being recessed in the dome. Then I just side cap the ground strap.

 

Pic's of each will load off to the side.

 

Projected tip. (BPR8ES)

What do you mean by "side cap the ground strap"?

your supposed to run the BR8ES with the stock coil because of the resistor.

 

realy? I did not know that. mine came brand new with the non resister plugs, and I took it out of the crate and put it together. and the manual shows either one for replacement
