Decided to start a new topic instead of adding to my other for sale post. I'm selling a HKS Knock Amp & O2 sensor used on my my01 for a little over 1 year. The car is gone, and it's easier to sell it by itself than with my Vpro. my price is $625. These retail at $890 + O2 sensor and install. I still have the box and packaging at home as well. This unit was great in reading my A/F





Thank you

Still have the JL stealth box as well as the Bride Rails (MO) and Fcon Vpro Harness in my other thread.
