Heads up!! For the 2020 Si Sedan, there is a third bolt for the intake on the bottom of the car. You need to remove the bumper and undertray to get to it. Also, although you can do it that way, my hands were small enough to squeeze around the intake box and start wrenching at the 2 bolts for the springs. The one on the side of the transmission is next to the trans mount itself. You need a spanner or preferably a ratcheting spanner to get to that one. But the overall feel of the transmission is now AWESOME!! Be warned, your 4 screws for your intake box are EXTREMELY brittle. I do not know what Honda was smoking when they put such crap screws to hold down the top of the intake box. I broke 2 of them and replaced the screws with stronger ones from Home Depot. If you have small hands, this job becomes even easier. Good luck and enjoy!!
