I have a Mallory nitrous 6 ignition box. This is just like the Mallory 6AL, but has an ignition retard built in when you are spraying nitrous. It has the same easy to adjust rev limiter too. This box is brand new and never been installed. It sells for $265 at summit, I would like to get $175 shipped to the lower 48. I will get pics posted later.
