Performace Air Filter ??????

[CrewCabDiesel]

After doing a search on the subject there seems to be no firm answer which air filter system is the best. So what air filter is the best in air flow, filtration, mileage, and reliability ? Also do I need to worry about water and mud getting into these filters that don't use the OEM air box ? I am currently using K & N and my filter minder is almost to the red line with a new or cleaned K & N.



Thanks

Kyle

I'm running a Fleetguard BHAF with a Mallory Shield. Not to say thats a performance filter like an AFE or K&N... but I have thought about your same question alot. I'm worried about getting my BHAF wet in downpours or the carwash since its paper. But would a Mega Cannon be any better in this situation?? I dont know.



I think any performance intake system, irregardless of its flow volume at whatever column of water they use, will provide all the air you could want. That to me is really not this issue.



I think flow, mileage, filtration, reliability are subjects that no one filter can provide at the same time 100%. They all do one or the other better than the other brand or type. I'm getting a Mega Cannon or the K&N full system. I just hope I can spray my truck off without worring about getting it wet through the openings between the hood and fender.

air filter

I haven't tried it yet but I read somewhere you could

buy a sock that slips over a mega canon that helps

protect against water and dirt ect. Oo.

The stock filter and it does OK in air flow. If you do run a non-OEM air filter you need to do oil analysis every now and then and see how much dirty your getting in the old diesel engine.

Neil.....

I've had an AFE Mega-Cannon for ~25K miles. I've never seen a drop of water on it from either truck washing or any road operation. I had a K&N RE-0880 and pre-filter prior to the AFE, and I like the AFE a lot better. My air-intake tube and turbo blades have never shown residue of any type. I don't like the filter-minder and have blocked off the hole.



If you want the cover, here's where to get it.

It's ~$30. 00 shipped to you. The cover is washable, and really keeps the AFE looking like new. If you drive in dusty conditions and don't like servicing these oiled filters, I'd strongly recommend it. In spite of what a minority have said, I cannot detect any performance loss caused by the pre-filter. There's no doubt that it must restrict some air flow..... put it up to your mouth and try to blow air in and out, and you can feel the restriction, but if it's going to keep stuff out of the AFE, this is expected.

Does anyone know the part number for the extremely large NAPA filter that most run? Any help would be appreciated.

In our testing of aftermarket systems, this statement is not far from the truth. Filter and system flow characteristics don't begin to take effect until boost levels begin to come up significantly and you start moving fairly substantial quantities of air like you would with a B1, Piers 40, or one of the larger turbos on the market. Then a paper element, 550cfm filter, won't cut it.



So for lightly modified trucks, say in the 350 HP range, just about any system, whether it be BHAF, MegaCannon or Scotty II, will be sufficient to keep you in the safe EGT range at full throttle.



But past this power level, where your air is drawn from begins to be important. For each degree reduction in IAT, you'll see approximately a 2. 5 - 3 degree reduction in EGTs. Since underhood temps around the turbo can be as much as 60F higher than outside air temps, drawing underhood air alone will no longer provide sufficient cool air to keep EGTs in check when the throttle is being applied aggressively. This is why systems that draw outside air such as the Scotty II or Volant show consistently better EGT reductions than a MegaCannon or aFe filter laid under the hood.

Excellent post Rod.
