04 cv airbox or marauder airbox? - 03/10/08 02:20 PM

i used the search function, but couldnt come up with much.

i have a 03 cv with stock airbox and tube
70 mm tb

i want to go with an 80.

should I do the 04 vic 80 mm box and meter?

or marauder airbox ?

which one has a different wiring plug for the meter?

which vip tube? 04 vic?

thanks in advance!

I would go for the marauder maf and box, it can handle more airflow before it pegs the maf voltage. The 04cvpi has the different maf plug. I like the 06+ ziptubes, they are a hard plastic instead of the soft rubber like the 04 ziptube. With the 06+ ziptube you will need a small breather filter for the pcv tube that usually goes into the air intake tube, they only have one vacuum port on the 06+ ziptubes \:\) . you will also need a tune to calibrate that MAF to your pcm.

I highly advise against this. Though it would work it will be sucking in un-metered air for the PCV system and will cause your air fuel trim to go lean.

Really, never had a problem with that.

Ditto. I have the '06* inlet tube and have the street side crankcase ventilation hose relocated to the inside and forward on the air box lid. Pre-MAF post filter. Car an computer likes it.

Doesn't that just get your MAF dirty much more quickly?

Yea, but wasn't your car dynotuned?

The tuner could adjust for your setup some right there and compensate to keep your a/f trim nice and flat. Some guy on here with no tune, or only getting a "mail order" tune can't adjust for that and as a result would run slightly lean from sucking in the unmetered air. It would be the same as if there was a large vacuum leak, as the MAF is not registering the extra incoming air. Know what I mean?

Yeah i get your drift but i've never had any problems with it, tunned or untunned, but yeah i could see it being a minor problem if you put a monster coone on there

I think he is saying he has the PCV SUPPLY tube at the airbox, but the PCV return is still at the plenum.


He has an 05 so his adjustments to the PCV return are limited (uses stupid locking clips on the return hose and the PCV is heated)
The PCV supply is the larger one, before the t/b, and feeds the PCV system

But why does the maf sensor need to know about air that is coming from the crank case, as the tube that goes into the air tube draws the air from the crankcase when the throttle plate is open and its all after the maf sensor to begin with. Im trying to figure out both of your guys reasoning. I also have a breather on my valve cover just like quick and have never had any problems and neither have people that i know that have the same set up with out a tune. Not saying that your wrong or not.

I believe that the pcv tube sucks in clean air from the intake tube, not put crankcase oil/air back into the intake tube.

Russ got it.
The PCV system uses vacuum from the plenum to draw clean air through the crankcase to vent it. The air is supplied from the intake tube, before the throttle body of course so it's not restricted by throttle position. Air is not drawn FROM the crankcase through that tube into the intake tube (pre-TB) like you're saying - that would not only render the PCV system useless at lower throttle position but since the PCV valve is on the other side would allow the entire intake to be coated in crankcase oil vapor In addition, the PCV is designed to only flow air the correct way - that's why it has the small weight inside. Air can flow through it to the top and into the plenum, but not down and back through the crankcase.

All airflow into the engine is metered by the MAF to aide control of the air-fuel trim. By having the PCV system draw air from a breather rather than the intake tube, you are drawing un-metered air through the crankcase and into the plenum. This would cause the car to behave just like a vacuum leak - there is extra air being sucked in that the MAF did not see. And just like a vacuum leak, this extra un-metered air causes the air/fuel ratio to go slightly lean as the MAF is not metering this air, only the air passing through, so the PCM is using a air/fuel map for less airflow than you actually have and causes the HEGOs to see a leaner condition which has to be corrected.


Again, you also have a dynotune where this can be corrected. But someone with a stock vehicle, or one without a tune with this in mind WILL run leaner because of it. Probably not enough to cause damage or anything, but leaner none-the-less.
What I'm saying is on a stock vehicle it may work, but it's not right ;\)

Good Tech dRock!
03+ Panthers, the predominant sensors that determine A/F (and most everything else) are the HO2S sensors. Under certain conditions, 10% of intake air is from EVAP, PCV, and EGR systems. Some of it is 'good' air (EVAP) and some of it is 'bad' air (PVC/EGR) Oxygen sensors help manage fuel, ignition and (on 05+ Panthers) throttle in reaction.
The problem with drawing PCV fresh air from the the airbox is that air is at a much lower vacuum than the PCV crankcase to plenum vacuum air. Placing the PCV inlet as far forward as possible on the airbox lid works well, but if you look closely you will still see the intake manifold pressure bounce a bit when the PCV solenoid thumps on. It's not perfect and there are limits, but it works.
I would suggest to anyone the '06+ CVPI inlet tube. Because it has only one outlet, those with IAC and PVC will have to decide whether modifying PVC intake is worth the hassle.

-02s also use the HO2S sensors to determine A/F, but the MAF plays a part in it as well as effecting the transmission shift pressure and shift and tc schedule.
I had never heard of a 4.6 panther having a PCV solenoid, though, I know 05+ PCVs are heated and use quick connect couplings now as well as the screw-in base like all 03+. I have an 05+ PCV in the garage somewhere which just has a two wire hookup which the EVTM lists for the heating coil inside. The plenum has no solenoid for PCV on it. Where is it?

You're absolutely right, you were right all along.
You're absolutely right, and I was wrong.
Tapered check ball with heating coil to help prevent the ball from freezing stuck.

Are you being sarcastic or there actually is no solenoid?

i got marauder airbox and 04 vic zip tube
thanks JOE @ parkway Ford in adairsville ga!
Stuck it on the car just to putt aroudn in before i go get it tuned and it detonates like crazy!

i thought these cars had knock sensors??

Re: 04 cv airbox or marauder airbox? - 03/21/08 12:12 AM

03+ do have a knock sensor, but they can't adjust for an incorrect air-transfer (the PCM will only pull so much timing)


Put the stock MAF back in until tuned

My only question is who has specifics on how to splice the connectors for the maf snesor?I just purchased mine from a junkyard in the area for $50. I bought a tuner from lonnie from boc i just have to be able to connect it.

I am assuming that you have a 2000 CV from your signature. You have two choices then on the MAF connector. The first is the MAF connector you have now just plugs into the MAF sensor and you will need to make a hole in the airbox cover with a notch in it to hold your IAT sensor. Your second choice is to get this: http://www.blueovalchips.com/index.php?action=item&id=44&prevaction=item&previd=29&prevstart= If your ever want to sell the car in the future then you may want to go with the first choice. This info above applies if you got a marauder airbox from the junkyard. Anyway i don't which airbox you bought from the junkyard either. If you got the 04 CV airbox that has a completely different style MAF then your stock one and you would need a MAF pigtail harness from ford for that one also.

just email lonnie, he has instructions on how to splice the connectors
