With all of the fake plugs out there, it is good to know TSP will make sure you are getting a legitimate set.
You will not regret getting the KTuner V2 with the stage one+ tune. My 2017 Honda civic Si when from factory slow to what I feel like the si was supposed to be like. My throttle response is phenomenal, my car is much quicker, and I now feel like I’m driving an entirely different car! Thank you TSP
