I wanna replace my k&n filter with a new one. I just dunno if I should get another k&n or a different airfilter. I have heard alot about the afe, but thats about it. What would u get and where's a good place to get it?? |

I would go with an AFE stage 1 (magnum force) intake, and i think Dieselsite.com has the lowest prices, at least last time i checked they did, the Stage II would be nicer, but unless your truck is highly modified, i doubt it will make a big difference. Scott |

Was just wondering why you would replace your K&N air filter, is it damaged? because it is washable. I once had a Amsoil air filter, was pretty happy with it. Alot better filtering and they say it flows just as much air as the K&N. I now have a Tymar air intake, Very Happy with it. I wish I would have got it along time ago

I have an AFE Stage 1 on my truck and I really like it, but if I would have heard about the Tymar before I got an intake for my truck - that's what I'd have. I'd have to vote Tymar all the way!

For a drop in element, we like the UNI 2-stage foam filters because they flow more air than paper and stop more dirt that other perofmance filters. |

IMHO, I could never trust the OEM filter box to seal completely, especially using a washable type filter such as a K&N. Before I switched to the stage 1 AFE, I found that when I removed the K&N for its cleaning, the "gasket" around the filter had taken a set which I feel would not seal correctly when replaced. Also my air filter minder never moved even with a very,very dirty filter. |

Quote: Any independent data on that you would like to share? Reason is while a different system on a different vehicle I also use a 2 stage foam filter but it is not a UNI and I'm pleased with its performance after over 40K miles of use. Thanks, Larry keeper of the "little secrets" CLICK HERE

I've got the original Tymar setup but I welded a 4"/4.5" adapter to the filter end and attached a Dodge Cummins replacement filter. They are one of the highest flowing filters AFE makes. John |

Okay, this is all my fault. I should have mentioned that I got the truck used and it has a k&n FIPK on it. I am not looking to replace the intake, just the filter. I really dont have money for a new intake. I wanna replace the filter because I have cleaned it twice and it just doesnt seem to soak in the oil. I used the spray on oil and even the liquid oil, but the filter always comes out white. I dont have this problem with the k&n on my fourwheeler, so I just want a new filter, u know, start fresh. I dunno what the previous owner did to this filter. |

If you're looking for a Stage 2 we have them on sale right now, but you'll have to call for the sale price. If you don't need that much air, then the stage 1 is what you might want to look at. Either one - I'd suggest getting it with the Pro-Guard 7 media. If you have some questions I'll be glad to help you with them. |

You can get an SP Diesel Air Intake for about $60. Its basically just a really big air filter you put in place of the OEM air filter box. It's similar to the Tymar. |

belz, I have posted this before, but it looks like you might be new to the site, the following is the reason we ONLY sell AFE Pro Guard 7 products: The first test was done by a customer of ours befre he woudl sell ANY system at all, the second is off of a GM site , sorry, and the test was done by an independent lab called Testand in RI: 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 how much dirt your engine will take in if you use the filter for the duration that would cause the filter to become "dirty" enough to need replacement or cleaning.

belz, Get the inlet diameter size off the K&N filter and call one of the dealers and get a replacement AFE Pro-Guard 7 conical filter. That would be your best option. John |
