Automotive Air Filter Test

[ThebigHurtt]

one sided

the filter blocks more dirts but restrict less air flow which will cost you more on gas and possibly long term engine damage.

This guys a pro at marketing...kindof. Look at 2:44 real quick. Frame by frame here. As soon as he turns on that machines engine, and before he started sprinkling that stuff, the cloth puff thingy was already getting black. Sure, i can't say anything about these products, but that majorly lost them all credibility of this video

[Craziguitarman321]

I've been using the same K&N airfilter in my 72 plymouth for 2 years havent had the need to clean it sice its only gotten 15k miles on it in two years but i have noticed more power and yet no engine contamination. very faithful on oil changes so even if dirt gets by new oil solves that problem. I Completely flush the engine each time though. My 02 silverado, bought 6 months ago put 4k miles on it since i bought has K&N and more power and no engine damage.

[lifeisgood070]

@Craziguitarman321 you really tore the engine down? & idk why the oil would get dirty. The layers of piston rings attempt to keep oil down. In most cases when a leak occurs it is oil going up into the burning part of the cylinder. Dirt through the intake should have a much worse effect on valves, spark plugs, intake, and the cylinder before contaminating the engine oil. Engine oil gets bad when you rev your car before 180F and scrape off metal fragments.

The foam filter test was rigged. The video cut from fan cut off to removing the round white cloth tells the trick. If you look closely, you can see dirt getting on that round filter while going through the foam filter, but when the guy pulls the round one out, there is absolutely no dirt whatsoever! I would have trusted this much more had it been real.

[hippo459]

you can see dirt accumulating at 4.15- 4.18

definitely edited...

will never buy this fraud.

[skunkarific]

In reading the comments, I have to ask myself, "Since so many have disliked the video because it's edited where it gives the appearance of impropriety and is lo-res, not allowing the viewer to see the results well, why hasn't it been remade?" If these tests are done all over, get a hi-def camera, say, 720P, and have 2 versions, one edited (and not where it matters) and an unedited version. And do test against AMSOIL. Their oil filters are renowned, test their air filters too!

[Neroin88]

Some sportfilters give a few extra horsepowers. Seach "Steeda Air Filter Dyno Test - 2006 Mustang GT" for example. It gives the mustang in the test 5,9 hp extra. Probobly depends alot on what car you have.

[neuspeed79]

How does this filter compare to HKS' hybrid drop-in air filter??

[CREAMFILLEDANISH85]

to say all three dyno the same at all rpms is bbbbuuuuuuuullllllllllll crap ? more air then your car needs ? thats great ,,,,,everyone knows 100% that more air is more hp and trq ,,,,,,your top numbers could be the same but in the whole rpm range is horse crap,,,,, you send me all three brands and pay for the dyno on my 00 grand marquis and if there is no change at all i will give you 10xs what you payed for the testing and filters??

[camaroreturn]

So that means that your Truflow is better than AMSOIL air filter or what ????????

[urbex2007]

Oh, has the video been faked? Go to 4.18 and the thing inside the test unit shows dirt on it. At 4.20 the video has been cut so there is no continuity, but the thing lifted out of the test unit has lost ALL the dirt that was allowed through by the filter. I was going to buy one until I saw this - it's a faked test, no other explanation for it.

I am very disappointed a company would fake a test video. That gives the company a bad name and makes people like me doubt the product is any good.

[NoDakBees]

Wow, first time I've ever heard or seen something like this. Why isn't it in the auto stores yet?

[ArmyDeUno]

Does anyone know how I can contact True Flow??? I tried to google them, but I just get directed to different wholesalers. If someone knows of a contact number or website, please let me know.

Thanks!!

[ArmyDeUno]

Where can I purchase one of these filters? Are they good?? Thanks!

[SIMPLEGUY423]

they dont make airfilter for 350z sucks

[akclan33]

hmmmm.....why did they cut off at 4:20 and showed the "clean" cloth afterwards? they didnt cut off from the other filters so why from the true flow filters?"

[akclan33]

[alfie677]

is this better then k & n air filter?

[redthirtyone]

How does this filter compare to the Amsoil EA filter?

[SigEpBlue]

If the 'dirt' is 0-300 microns in size, what is its breakdown, i.e. how much 0-5, 5-20, etc.? I think you'd be farther ahead doing several consecutive tests with homogeneous 'dirt' samples. I'd love to see how they do with smaller vs. larger particles.

Props to you guys for realizing filtration >> flow. A couple of horsepower at 6000 RPM on a daily-driven vehicle is NOT worth any decrease in engine life.

[SoundGuyDavo]

exactly, so they used like 2 micron dirt to make the K+N look like crap ?

[TeamTrueFlow]

Yes. When we take the filter out of the original packaging and it comes pre-oiled.

[Mito2009]

was the gauze filter oiled?

[TeamTrueFlow]

The gauze air filter flows better than the paper air filter and the True Flow air filter when clean out of the box. Once the filters get dirty, the True Flow air filter flows better than the paper filter or the gauze filter because it has greater dust holding capacity.

[EpiDemic117]

@TeamTrueFlow WAS THE GAUZE FILTER OILED! YES OR NO!

[ronburgendy245]

which one has more air intake though?

[raidacaipo]

why did they cut off at 4:20 and showed the "clean" cloth afterwards? they didnt cut off from the other filters so why from the true flow filters? and also even though its filtering your air intake, it doesnt mean its gonna provide the good amount of flow your engine needs in order to gain power..

[TeamTrueFlow]

I dont know why the video was edited differently when showing the True Flow filter results. We have done this demonstration over 1,000 times at various shows including SEMA. The results are consistent. The paper filter does better than the gauze filter and the foam filter does better than the paper filter. If we are in your area or you are in ours, we would be happy to show you the test in person. All three filters flow more air than a standard engine requires.

[RotaryJunkie]

@TeamTrueFlow I reckon there's a good reason for the True Flow filter doing better in this case for filtration... The foam has a good bit of exposed area on all sides where air flow can happen, and given that the dirt only rests on a small portion of the filter air will take the path of least resistance. The problem here however, is that the area that is a path of least resistance in this test for the True Flow filter is nonexistant in 99% of applications. In which case it is no better (cont'd)

[RotaryJunkie]

@RotaryJunkie than a normal "surface" filter. The top layer will grab dust until it's nearly clogged and restrict flow. In this dream world (or indeed if you feel like doing a lot of cutting to your airbox so that it merely has a retainer for the filter instead of being an airbox) the TrueFlow may well come out on top, but in the real world it will most definitely NOT flow as advertised once dirty. I dare you to make a plexiglass airbox based on an existing design and do the test again.

[NoDakBees]

@TeamTrueFlow I think you need to re-do this demonstration because we are not all convinced due to the video cutting on your last filter.

[1PARADOXXX]

@TeamTrueFlow Dear TrueFlow.... make this demo again... No editing, AND please use a hi def camera

[Muffduster]

@raidacaipo You obviously didn't watch the entire video.

[akclan33]

@raidacaipo hmmm.  sounds kinda like fishy to me also raidacaipo,yeah why was the scene at 4:20 edited ive seen that done with alot of demonstrations.

[oursedatedyouth]

@raidacaipo to give us misleading advertising. which is wrong :(

[marquerr]

@raidacaipo No it's not true. The video has been cut in both of the other cases too (ie. when raising the wad after testing the paper and the cloth filters) - at 1:50 and 2:55. Also, you can see it real-time, when he's feeding the dirt; how much of it accumulates with the paper and gauze filters, and how little with the foam filter.

I'm not saying if this test is tampered or not, I'm just clearing up the above facts.
