The testing is based on statistical methods. I work with statistics on a daily basis in my line of work. You can make statistics support a number of different sides depending on what you want to do with the numbers. I have seen this testing before, and it is probably as accurate as you will find. Question is how worried about those sub micron particles are you? I've always run K&N on what I could and have nver had a failure due to those tiny particles. Take it as it is... Numbers!

 

What a joke I try and post some information that none of you are aware of and this is what happens? While that test may not been perfect to accused the members of Diesel Place of being biases is BS. I have see dust in more then a few intakes of K&N equipped vehicles.
I hate to post links to another forum mods if you want delete them I would understand here are some of the threads from DP.

All that test really shows is the AC Delco is great at catching dirt but is more restrictive than say the AFE or K&N. Thats nothing new in the world of air filters. To gain air flow you have to give up restriction. What causes restriction in the filter? The media. The more you combat trying to catch smaller and smaller particles the more media you need, making a more restrictive filter.

 

Feel free to post links to other sites, we are here to learn and provide a mediam for information to be shared. To do this we need to provide info from any good sources we can find.

At the same time please don't take offense when others offer their opinions also. Debate and comparing info is one of the best ways to keep info accurate as well as up to date. Many of yesterdays proven facts are todays old urban legends.

 

Water under the bridge I just wasn't happy to see the accusations flying.

99 is dead on the point of the test was to provide info so members could chouse a filter that would suit there needs. The stock 01-05 Dmax filter assembly and filter was flow tested IIRC to flow enough air to support 500HP and the 06+ are even better.

 

Are there links to those tests? I'd be curious to see how well the AC Delco did with the increased flow.

 

settle down dozer. I was just debating the point that everyone of those tests show AC delco on top with no other filter even close. again Im not saying the data is incorrect Im just saying that when looking at the overall picture of flow and filtering AC DELCO isnt the one on top.

 

SAE J726C is all I"m going to say...

 

Same here

I'd be happy sell a drop in for an 06 cummins actually I don't think I could do that to a fellow ctd owner. It gunked up my turbine wheel in about 2K miles.

 

Which says what? That he didn't use it or that it isn't a good test?
