Is anyone using this NGK BKR8EIX ???
I need one to support about 600WHP

Thanks

 

i'm using the 8's - should be just fine for your application.

 

Same here.

 

leave the preset gap for that HP level?

 

Wouldnt two steps colder be wise for 600whp? I use this plug in my 350whp application

 

When you say 8's do you use these BKR8EIX ???

 

I am 99% sure the answer is yes.
The NGK iridiums are common among FI s2000's on these boards it seems. I am using them myself as well.

Last year when I did my first build, I was scouting around for plugs since I didn't know what to get, I didn't even know what alternatives there were. Out of luck I found the bkr8eix plugs. They work great. ~350whp setups.

For higher hp setups 9's could be used I think.

 

Yeah I use the BKR8EIX-2668. 350whp

Depends on the set up though, I supose these plugs could work well on a 500-600whp set up if your using water/meth injection or some other high octane race fuel. Otherwise I would think 9's would be a safer bet.

 

are people gapping them down or keeping factory gap? Thanks

 

i go as wide as i can run without misfires. Each car seems to react differently.
