Spark Plug for n/a

Postby Shinigami! » Sat Mar 20, 2010 2:08 pm

hey guys did a search on this particular topic and i did find a thread but it wasn't really telling me what i wanted to know.
so I'm in the middle of putting individual throttle bodies along with toda camshafts and what not but i was wondering what kind of spark plugs should i run?
i previously owned a onevia and when i owned that i ran 0.8 gap ngk copper plugs. around 4$ a pop.

so what i'm asking is what gap should i run and if the ngk copper plugs are good for me to run for n/a application?

From what I have read, the spark plug gap should be between 1.0-1.1mm (0.040 - 0.044").

John,
If its a 1600 run NGK iridium BKR6EIX-11
1800 BKR5EIX-11

If your running high compression go one range colder, ie; 1.6 run BKR7EIX-11.
The plugs are pre gapped so don't need resetting.

Running std plugs will probably fowl up due to the amount of compression and fuel your running.

Just my 2.2c worth
