Just bought your HKS A/F Knock Amp and want to get it up and running ASAP? Well, you may need some of these accessories. An O2 sensor will help (might as well keep a backup) and you may need a Senson Boss to install it in your downpipe. A Harness might be necessary and might as well grab a Connector Set while you’re at it.
