FM O2 signal modifier

Product Review (submitted on March 4, 2018):
I received this piece from purchasing the FM MSM Intake Kit, and I am really happy with the results. I was a little bit lazy in the beginning, because after the intake installation, I just truely forgot and put it aside until now. The MSM has the NOTORIOUS boost hesitation, but once I installed this to my car (Stock ECU), my car was not hesitating AT ALL. This piece is pricey to purchase on it's own, but I believe for the price you're paying for, it is really such a great deal!
