2012 Civic LX Intake Duct

I am new to the forum and I just wanted to post something of a PSA about the intake duct on my 12' LX. Its a 5 speed manual, which I bought at 66,000 miles. Ever since I got the car it would act a little "touchy" whenever you gave it a lot of gas in a short amount of time. The whole car would buck a little. It did the same when shifting at 3K + RPM. I thought it was just me, dropping the clutch too fast. I was under my hood one day and decided to do a visual on the engine looking for anything loose or broken and I found the intake duct between the air filter and throttle body had a huge split in it. I got a new one and installed it today (Not exactly fun), and took it for a test drive afterward. I was kind of amazed of how much a difference it made. The car shifts so smoothly, and accelerates at a constant rate with no sudden jolts. I thought I had either clutch or transmission problems, but it seems it was just the duct either opening up and shoving too much air to the engine (trust me it didn't like it). The car shifts like a beauty too now, don't know if it has to do with the vacuum line coming off the duct. I hope this helps someone that is having the same issue I did.
