Just wondering these Questions....

1.Are there any HP increases or better yet would I free up HP if one switches to an Electric Water Pump?

2.Do thicker spark plugs mean more HP? Or do they mean just a better maintained RPM Band?

 

You may gain some from the waterpump. It will free up the valvetrain. As for spark plugs, nu uh.

 

Elec. Water Pump = no parasitic drag due to the camshaft spinning a gear for the water pump.

CSI is ~$139.
