Pe:

I previously sent my questions about my Evolution to Horizon Hobby's technical support.
No reply as of yet.

The spark plug box appears to indicate a spark plug gap of 1/16 mm, and a torque
value of 1/2. Is that 1/2 newton/meter?

Strange gap measurement for a metric value?

I just found the NGK web site, and their installation instructions:

http://www.ngksparkplugs.com/tech_su...x.asp?mode=nml


This web site sells the plugs in the US, and lists specs for the 5812 CM-6 plug:

http://www.ngk.com/results_cross.asp?pid=5812&x=0&y=0

Says it is a 10mm dia, .339" reach, 8.6mm hex, gasket seat, non resistor, clip style terminal.

According to the NGK installation instruction web page above, it appears the correct installation
torque in an aluminum head is 7.2~8.7 ft/lbs.


Is the correct gap really 1/16 mm, or am I misreading the box?

Thank you,
Chris Shaker
