David and KR builders/flyers, What David says is absolutely true, the combustion chamber is not configured for dual burn plugs and this is an archaic technology when mags were hit and miss reliability. It will not give you more power and if it does it is not enough to make it significant to extra cost and just another thing to go wrong. With only coil and points change my KR has been flying for 20 years with one Slick mag. To each his own! Happy building and Flying!
