Anyone use the MAC intake system ?

Saw it on www.rpmoutlet.com
List is under $200.00 and it looks really good with the chrome tube and all but is the filter up to par ?
Better yet, does AFE make a Pro Guard 7 filter to fit that type of intake ?
I'm going to do a lot of dress up items under my hood and the chrome tube will go good with the turbo piping when I get them chromed.

Re: Anyone use the MAC intake system ?

UNBROKEN,

far be it from me to tell you what products you should purchase but consider the followinf info about air filtration and the different types of filters etc. We stock and sell ONLY pro Guard 7 because of this info:

Here's what Dan Montegari of Precision Diesel Services says about advanced FLOW engineering's Pro-GUARD 7 filter media:

HIGH FLOW AIR INTAKE SYSTEMS

WHO IS THE BEST & WHY!

We received many letters asking which high flow air intake system to use. We decided to test a number of manufacturers’ systems to determine which system was superior. We tested each system and found systems manufactured by AFE (Advanced Flow Engineering) were the best by far.

Diesel engines use seven times more air than gasoline engines of equivalent size so clean cool air is a must for extended engine life, better fuel economy and additional power. A higher flow of intake air coupled with a high flow exhaust system allows for more power, a better fuel economy, extended engine life and reduced exhaust temperatures. On the other hand ingested dirt through the air intake system becomes Silicon in the engine oil, which is a harsh cutting agent and can damage your engine quickly.

We tested three very popular systems. I will not mention the names of the other systems as a courtesy but I will explain what problems we found with them. We evaluated the systems by a number of criteria, filtration protection, flow, and design, easy of installation and cost. Almost in the beginning of the tests we realized in most instances a new intake system was necessary to achieve our goals. We needed a kit that used mostly outside air and not hot engine compartment air. We decided to use systems designed to use mostly outside air.

Two manufacturers claimed their systems delivered cleaner air at a higher flow but this was far from the truth. We did not believe any of the manufacturers’ claims and tested each system by operating the vehicle 3,000 miles and performing an engine oil analysis to determine Silicon levels in the engine oil. The vehicle we used has an engine oil analysis performed at every oil change so we had a Silicon number of three (3) to base our tests on.

The first manufacturer’s system was fairly easy to install but we had problems with the oil used to coat the filter also coated the Mass Air Flow Sensor causing a service engine lamp to come on. I called the manufacturer but they had no explanation as to why this should happen but they had this complaint before. Through the three thousand mile test I had to clean the sensor three times to stop the service engine lamp from coming on. When the oil analysis results came back, it was discouraging with Silicon levels at eleven (11). I almost could not believe the result so we changed the oil and filter and repeated the test. The results were almost the same eliminating this manufacturer quickly. I contacted the manufacturer to discuss the results and they were not helpful and basically said, “what you see is what you get”!

We installed the second manufacturer’s system again changing the engine oil and operating the vehicle for three thousand miles. The first problem we encountered was the service engine lamp coming on and I thought the oil they used was coating the sensor again. I removed the sensor and found some oil on it which I cleaned off and reinstalled the sensor. Within ten miles the lamp was on again. I removed the sensor but there was no coating of oil on it. I then placed our scan tool on the engine and quickly discovered the airflow rate was too high for the sensor. I then realized the manufacturer had moved the position of the sensor into a higher airflow and velocity position trying to squeak a little more power from their system. I continued the test having to deal with the service engine lamp throughout the test period. The engine oil analysis gave a Silicon reading of eight (8 and along with the engine lamp problem did not give the manufacturer high mark but I felt if I discussed the problems with them maybe we could overcome them. I placed four calls to the manufacturer and I am still waiting for a call back! This surely eliminated this manufacturer.

The third manufacturer we tested was AFE (Advanced Flow Engineering). We used their Magnum Force air intake system. We operated the vehicle for 3000 miles and when the oil analysis came back it was promising with a Silicon reading of five (5). While five was the best Silicon result we had, it was not good enough. I called AFE and was pleasantly surprised when I discovered they were truly concerned. I spoke with a Mr. Paul Hardley who suggested I try their Pro-Guard 7 media they were about to release. He explained the new Pro-Guard 7 media was five layers of progressively finer mesh medical grade cotton gauze with micro fibers that attract smaller and smaller particles as air passes through. Combined with the five layers of medical [gauze] media, there are two layers of non-woven synthetic polyester fabric with random porosity. The filter media is sandwiched between two layers of aluminum wire mesh. He agreed to send two Pro-Guard 7 filters for a new test. I installed the Pro-Guard 7 filter, changed the engine oil and operated the vehicle for three thousand miles. The engine oil analysis was excellent with a Silicon reading of below three (3). Finally we found an air intake system that gave us a higher flow rate and better filtration. The AFE Magnum Force air intake system is a well designed system, easily installed and uses about 90% outside air. The filter is cleanable and the oil used to coat the filter is patented because it is formulated not to affect the airflow sensor.

Another positive factor of the high flow system was the fuel economy increased about ½ MPG in mixed driving and 1 MPG during highway tests. The filter media used by AFE will not collapse if it gets wet or subject to high boost pressures. They also offer pre-filters for most of their applications for very dusty or dirty operating conditions. We carry a full line of AFE products with Pro-GUARD 7 media. If you order an AFE system from another source, make sure it has a Pro-GUARD 7 media.

A very important factor in this test was the manufacturer was willing to discuss problems with their products and help to overcome them. My hat is off to Paul Hardley and all the people at AFE!

Re: Anyone use the MAC intake system ?

Thanks Mark.
I plan on using nothing but the Pro Guard 7 filter.............i'm just curious as to the fit of the MAC system. I'd like to have the chrome tube IF the AFE filter will fit it.
Reading through old threads here has convinced me the AFE/Pro Guard 7 is the only filter to use on these trucks.

UNBROKEN,

Another thing to consider, that has been hashed to death here, is the underhood heat temps in the summer that effect the intercoolers effectiveness with an exposed underhood filter.

Re: Anyone use the MAC intake system ?

I just purchased a 2004 F250 with the 6.0, and I will be using the MAC air intake on my truck for several reasons.
• The MAC should free up more air to the turbo than any other airbox out there due to the fact that it is an open-air element. Another option to consider is the elements made by companies that even offer flow through the end of the filter.
• Although the air the MAC will be ingesting is heat soaked from the engine, it still will offer much more volume and flow which will keep the heat down vs a airbox unit that is in negative pressure under boost and having to work to get its air.
• An airfoil or baffle could be used to blast the make filter with ambient air from outside of the vehicle, which would make the benefits of this system boundless.

Another thing to consider with the 6.0L is they run a MAF sensor which is very sensitive and can become nasty and give false readings if covered from oil residue from your filter. I am unsure on the MAC system, but some companies offer washable gauze filters that contain no oil.
