Plug-and-Play Products Using The Patented Kaizen Relay


  • This is definitely the most innovative product up here! A rad new product for the aftermarket and I think it will do well!

  • On my car I have your relay and never had an issue with it. Boost control works every time, the output for the fuel pumps works every time, never had an issue since the first day I put it on and that is a year now.

  • @kaizenspeed relays are just amazing! Solid state relays, no old school spade connectors. These things share 1 power supply meaning you can simply just snap another relay on and share the power from the other relays.

    And my favorite being the test button on top. Easy to test and diagnose at the race track!
