Pro guard AfeWhat benifit

[DPKetchum]

just installed a Pro-guard 7. Had 10k on my truck. Old air filter just about looks NEW. I cant tell MUCH if any difference in running or fuel economy. Course I do need gauges. What difference has anyone noticed? Last trip was a average 15. 4 running 70/73 mph whole trip. Just got back from Islands near Charleston S. C. to Athens GA. What speeds do SOME of you all drive these trucks with 4. 10 gears??

DP I doubt you'd see a mileage increase, what you should see is a bit of an EGT reduction especially when you start cranking the HP.



Man my stock filter was CAKED at 10,000 miles. I guess that's the difference between Georgia and the desert region of Washington State!

Mine looked NEW. My buddy just turned 30k and started to replace his and said looked OK and left it. But I have another neighbor with 100k on his transporting horses said he replaces his monthly. I noticed nothing in noise,power,fuel mileage with the AFE PRO GUARD 7. I did with the Banks exhaust from the jump street.

DPKetchum,



Did you replace the factory airbox with the Magnum Force intake or did you just replace the factory paper element with a drop in?



I think the factory airbox is pretty restrictive along with a filter that is on the small side. Therefore, even a quality drop in like the aFe will probably yield a very small gain if any.

Mine was caked thick at 8,000... . I noticed a little better mileage and lower exhaust temps with the AFE... . which also gets dirty pretty quick, but just have to wash her off and re-oil.

I replaced the entire air box with a AFE PROGUARD 7 and a outerwears filter.

DPKetchum,



Here's some test data one of our Distributors did, they are extremely precise and do excellent testing in the past so I expect this to be very accurate:



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!

This is the reason we stopped using oiled foam filters, they were the best alternative until Pro Guard 7, now that's all we have available.

As far as the speed goes I run between 70 and 75 usually, about 2150 to 2300 rpm. Any slower on the highway is almost unsafe around here. I am looking forward to getting 19. 5" wheels and tires so I can lower my RPM at those speeds, I plan on getting 265/75/19. 5 which are 34. 3" tall. The current 265/70/17 are 31. 8" tall should reduce the rpm by about 170 in OD.

 

[DPKetchum]

I also want some 19. 5s to lower rpm. I runs 70 to 75 and wish it didn't crank as many Rs out. NEEDS a 7th gear a real OVERDRIVE. Article was well written about the Pro Guard 7 its just I didn't really notice squat with fuel mileage or performance. I did with the exhaust change.
