I received my Black Boost CAI did a test fit. Not complete instructions but will help get you started. Very straight forward. Haven’t tried putting on the engine cover yet. Will report back soon How it started Removed engine cover Removed MAP sensor Sensor unplugged passenger side Sensor unplugged driver side Factory air boxes out Use extension provided here Put charge pipe and filter together I did this one backwards and had to remove to put filter on Driver side sensor in air box Sensor plugged in
Awesome. Mine should be here any day now. How long did it take? Any specific pointers?
With what you see; it’s straight forward.
I’ll be removing assembling in its entirety (after painting) then installing. There are some bolts for the top half engine cover which will be impossible to reach when on the engine.
I wanted to get the boxes on as I had road trip and wanted to test the mpg (320 miles @ 72mph = 20mpg)

I originally placed the passenger side (PS) MAP sensor in the charge pipe. Driver side (DS) MAP sensor was placed in the air box. Drove a few miles (really just let it run for a few minutes) CEL came on.
I moved the PS MAP sensor to the air box and plugged the charge pipe with supplied part. Cleared the code with iCarsoft MBII (code doesn’t come back to anything). No CEL. Did a 0-60 pull and a 60-110 using the trusty butt Dyno. 0-60 felt stock, but I’m not tuned. 60-110 felt like having the air box spacers and racechip rs (I removed the racechip). 80-110 felt a lot stronger.
320 miles running 93 octane with 1 bottle of octane booster. I ran it non stop for 5 hours; no CEL.
Reached the city put it in sports mode and played with it. All good.
Just for kicks and giggles, I swapped the DS MAP sensor from the air box to the charge pipe. Ran a few minutes, then CEL.
An interesting thing I noticed with one MAP sensor in charge pipe readings for the IAT = 57°c. With both in the air boxes IAT = 62°c. I’ll be testing with both MAP sensors in the charge pipe and take some readings.
This has 2 rubber grommets

Reason: Title change
I got it because the prospect of making the air cooler was worth it, even if minimal. The power gain claims seem super high, but fairly consistent in that regard across manufacturers.
It's hard to tell from the pictures but does the intake seal to the bottom of the hood? From what I can see, it doesn't look like there is any type of seal to keep the hot air from the engine out of the intake?

There’s more power in the higher rpm range, again I’m stock, it’s noticeable but it’s on the higher side of 3k rpm. Tune will more than likely bring it out sooner
As for sound, the intake is noticeable and has a slight blow-off valve sound when releasing the accelerator. Very noticeable when windows up and music off, sometimes drowned out by the exhaust.

It does not seal but very little space. My IAT’s are lower with the BB CAI (-2°) versus the stock box with UPD spacer.
Did you have trouble getting the rubber grommet over the metal pipe that connects to the filter? My pipes are definitely bigger than the corresponding oem air box outlet.

I unscrewed the clamps and pushed it on, then retightened the clamps
I got them on and it didn't tear, but I am going to check them frequently. Had to get out the little plastic things they use to pop apart interior panels and lever it in.
I did get serial number 1002 (which I assume is the second one they made, starting at 1000) so that's cool haha.
Noticed a good bit of responsiveness and whistling/intake is much louder. Sounds like a storm is outside haha. Pretty cool in parking garages.
