Congrats, guys! Hopee you enjoy the CAI even more than expected, and don't forget the pix!!!

Larry... No problems with driving in a torrential (1"/hr) downpour here... Plus I haven't had soot in my exhaust tips in 2 weeks.

I guess based on your analysis regarding the impovment in reduction of black soot on the tailpipes makes the theory more credible,so guessing there is less exhaust gasses going into the intake so the temp's come down and there is less soot,lower intake temps=more dense air/oxygen=better performance,less soot in the intake.

I have really been struggling to understand how soot would go down with any intake. This caused me to start reading about gdi and soot production. I found a pretty decent artical that talks about soot generation, causes, variables and future solutions and regulations.

Egr is used to lower cylinder temperatures by the introduction of inert gas (non combustible). Our cars do this not by injecting egr gasses in the intake, but by manipulation of cam timing. Since only our intake cams are variable, unlike our f150 brothers our egr "capacity" is a little more limited. But we still get reversion through the exhaust port to the intake stroke.

All that being said, can someone explain how a cold air intake alters the variables that produces soot or alters the already functioning egr activities of the variable cam timing?

As My E85 blend goes up, the soot disappears also. I have no idea what would cause an intake to change it.

I can confirm that the soot is gone from my pipes too. I clean them on a regular basis and since I install this intake I have not gotten any build up. I have put over 2000 miles on the car too since then, filling up at various different gas stations and brands of fuel. Not sure why it happened with this intake but I know that it has.

Maybe removing the pulses caused by the accordion?

Neither do I. Earlier testing on my car showed no dyno difference between stock intake and filter and with filter disconnected at the accordion leaving an open hole... (3 separate comparisons using BTB pulls)... Therefore I don't really believe there's more air getting in, but it is possible, I suppose, that in moving the O2 sensor from the turbulent OEM box to the smooth pipe on the MDesign CAI the resultant airflow may be causing the sensor to send a different signal to the ECM... I cannot explain it, but continue to see essentially no tailpipe sooting...interestingly the very slight bit I've noticed (and I mean almost nothing) is in the right tailpipe tip.

Two questions:
First, does the tab on the side of the MAP sensor needto be below the gromet on the Charge Pipe? I can't remember how stock was or even when I had it on the K&N.
SEcond, what postions should the MAP sensor be in?

So far I love the look of the MDesign intake, performance wise, hard to tell...It snowed and has been extremely cold here in Chicago since I got it. Was -2 this morning. Only draw back so far, is the whooos sound that I got with the K&N is gone.

TSS · January 05, 2015, 11:12:42 AM

^^ I just ordered an MDesign and sold my K&N to a member - I hope I don't miss the sound too much. LOL. . I just like the look of the Mdesign so much, that swayed me.

The reduction in soot would be nice, though I did not get much at all witrh the K&N either....

For Anybody considering this, Ahmed (MDesign) has really quick responses to direct inquiries. I like that - a lot.

The sensor on the intake pipe (the one that was on the OEM airbox) should be at about 7:00, fully inserted (the O-ring slot will be inside the CF tube...I took my O-ring off so it would not have a chance of ingestion by the turbos), and the sensor should be oriented so the widest part is in line with the tube (sensor it self is the bluish thing surrounded by the nylon) to expose the sensor maximally.

Don't need to touch the MAP or the TIP.

WickedSHO · January 05, 2015, 11:54:52 AM

That is the sensor I was talking about the one on the charge pipe. So don't use the o-ring that came with the kit?
If the o-ring slot should be inside the CF pipe, I don't think I put mine is all the way!

Sorry... Thought you were talking about the turbo intakes, not the hotpipes aka charge pipes... On my car the MAP has only one screw... put it in the same orientation as the OEM.

I had to free up about 1.5" of the sensor wire from the wiring harness to get the slack to seat the sensor to my satisfaction...of course, use the grommet that comes with the CAI kit to hold the sensor.

My CAI did not come with an O-ring ... My 3BAR MAP had one on it....use it to prevent boost leak.

WickedSHO · January 05, 2015, 02:08:22 PM

I think I confused myself and maybe you...Sorry.

I am talking about the sensor that is attached to the CAI....I think you gave me the answer I need with your first repsonse.

Sorry about that....

MDesign Performance · January 05, 2015, 04:06:27 PM

Ok I'm here to clear some things up!

Use the supplied o-ring to replace the OEM blue o-ring as it is not thick enough and the new one will provide a better seal, you should insert the sensor fully into the grommet to where the o-ring is not showing. Refer to the pic below for position and there is a link to the install guide as well.
