Karbonius Full Carbon CSL Style Intake Install and Sound Clip

Hey folks,

After ordering the Karbonius Full Carbon CSL Style Intake in mid-February, it finally arrived early last week. So let the install commence (hope you're ready for this photo overload):




Stock plenum/airbox removed:












It was Cinco de Mayo, so a margarita was necessary:






Blow by, what?!:




Dirty throttle bodies:










Removed and cleaned the ICV while it was accessible:








Clean throttle bodies!:














New Turner Motorsport throttle body boots installed:








ICV cleaned and reinstalled:




Swapped rubber mounts from stock box to the new Karb box:






Carbon Fiber sexiness:












Turner IAT kit supposedly fits all CSL intakes....EXCEPT the sensor they include 100% does not fit the Karbonius box:








THIS is the sensor I actually need. Waiting to hear back from Turner on whether or not they'll refund me for the incorrect sensor and swap with this one:



Needed to temporarily install the sensor somewhere until I get the correct one, so the tuner suggested putting it here for now:




Some fabrication (lol) work was required for the new intake to fit. Trimmed this plastic piece back about 1/4":




New CSL box installed:














Remote tuning time (courtesy of HTE Performance):










Along with the Alpha-N (CSL) tune (needed because I'm no longer running the factory MAF), I also opted for the cold start delete and a very mild burble (I was a bit skeptical, but he suggested I try it out and I am GLAD I did...it's so subtle, yet so perfect between shifts).


And tuned and all put back together:



















I took a quick, little video of me merging onto the highway yesterday where you can get a decent sense of the induction noise. I'd like to setup my GoPro in the car soon with a mic placed under the hood, near the opening of the intake, to get a recording of some legit induction noise. Soon!

You can't really hear the burble tune (luckily), because it really is mild and is perfect. It causes the smallest of pops between shifts and letting off throttle after WOT. It's VERY subtle, but I dig it.
