Hey guys,
Im trying to find a good plug to run in my turboed 12a. I know i could use the 2nd gen trailing plugs put you cant adjust the gap on those. I currently am running b9es ngk's but the problem is to tighten these plugs you use a standard spark plug socket(13/16, i think). But this is different from the stock br8eq-14's which have a smaller 5/8's head. Basically the eyebrow over the sparkplug hole interferes with the 13/16 socket and there is no way to torque the plugs in there.
Is there a good plug in a 9 or 10 heat range with the 5/8's head you 12a turbo guys are using.
Thanks

 

Racing beat recommends the NGK R6725-10.5 on some of the Turbo applications. I do not know what the head size is though.

 

You can buy BR9EQ-14 from O'Reily's or through racing beat. I used them when I ran nitrous.

 

Sorry, forgot to say that RB calls them "Streetported Highway Plugs" or something similar to that.

 

I run B9EGV's all around.

 

NGK B9ES , and set the gap at 14 thousands. You can get these anywhere. About a couple bucks a piece.

 

I'm hella new to technical car basics. What do you use to gap your plugs such that 14 thousands accuracy is achieved? I bought some plugs (only ones Kragen's has for the 13b) and was told by their PC I needed to gap them at .055. So, I got this tool, the disc measuring thing, and went to measure the gap. It was a bit tighter than .055 so I bent the metal part back a bit with the measuring tool (LOL) and the porcelain (of whatever) part chipped a bit. Gay, lol but I didn't know how to really get in there proper and adjust it.

 

The reason for gapping them tight, is so the spark is stronger and doesn't get blown out. Have you ever heard of feeler gauges? It's scary that you do not know how to set the gap on your plugs. They make thin wall sockets for these size plugs.
