    Good for the price

    Kit was easy to install, I did not use the micro switch as I’m using Holley terminator to control the nitrous but all works as advertised tho. I knocked a star because the solenoids are loose in the housing, no way to fix that but doesn’t affect operation, just an fyi if that bothers you I wouldn’t buy this. It’s under a shut hood and it works fine so for me it’s whatever.
