Gary,

The salesman at E-MAG told me that the improvement with 1 P-Mag (they no =
longer make the E-Mag) is 70% of what it would be with both P-Mags.

If I had the money at this time, I would put 2 P-Mags on my plane. The =
total cost would be $2,800. The price for 1 P-Mag is $1,100 or $1,300 =
depending on weather you change the impulse coupled side or the direct =
mag.

Don't forget that you also get to use automobile spark plugs.
