The HVI was a direct fit and the instruction guide was self explanatory. I do not have much experience working on my car and this went smooth. 110% would recommend
Easy install. Hoses that go to valve cover and intake manifold require so finessing but over all straight forward.
Got the Ktuner for my 2024 Civic Si, I mean wow! What a difference. This is the way the car should feel. Installation was a breeze, the software is easy to use. The included TSP tune feels so good. Car responds so well now. One of the best investments I’ve made for the car so far.
Knew I was going to need to upgrade from the stock clutch soon considering I had bolt ons and tuned. Ripped the gun and bought this flywheel with the stage 0 clutch kit and haven’t looked back since. The customer service was great and the jit even came with a few rv6 merch goodies!
