Want to go with a different Air Filter - Advice

[widman]

If you want the maximum filtration and increased air flow, get the Donaldson D080020 (horizontal) or D080026 (vertical) PowerCore. 99.97% efficiency and long lasting. The silicon adapter you need depends on the diameter of your intake.
I'm about to put one on my T100 this week, and have a couple of friends with Frontiers and one with a Land Cruiser waiting for them to come out of customs this week.

Thanks for the info Widman... Gonna see how this one holds up on the used oil analysis and by mileage and if I need to change I will consider your recommendation.

Maybe one of the Amsoil guys could answer the question, but I thought Donaldson made the A/F for Amsoil? If they do are they to this same spec?

 

[widman]

I know they make some for amsoil, but amsoil has a lot of other stuff too. One of the Amsoil guys can answer better.

Wheres a salesman when you need them?

Here PABLO, PABLO, PABLO...

I don't think donaldson actually makes the amsoil nanofiber air filters like your's, but they are made using donaldson's process. The powercore that donaldson makes is a very nice, but expensive filter. Powercore filters use fluted channels and look big rolls of toilet paper. From the picture on amsoil's site air filter it looks like their filters are cellulose w/ the synthetic nanofiber coating on them, does that sound right?

That is a Donaldson Ultra-Web picture of the nanofiber covering on that page. I have an original in a training presentation.

The PowerCore appears expensive, but it may last basically forever in US driving. When compared to the size filters you need in high dust areas, it ends up being cheap. A $60 PowerCore will outlast 3 Denso filters at $35 each on my pickup, and keep out 99.97% of the dust it gets thrown at it.

So I had a sample in to be tested by Terry and the mail seems to have lost the sample.

It shows that it cleared customs south of the border and then that it was on it's way to Texas but then the trail stops cold and no one is able to find my package. (3 weeks ago)

So now I have to wait to do another test to check the SI levels in my oil because I'm currently testing Red Line and it needs to be in there for a few runs so I get accurate readings.

I'M NOT HAPPY! Stupid USPS.

I'm w/ you on the powercore being a great filter and well worth the cost. I'm just gonna give the cheap filter I bought a chance to show me some decent silicon numbers and if it fails I'll be picking up a powercore.

Sorry to hear they lost your sample Stevie, but considering how you enclosed your filter and the amsoil filters are at least 98% efficient according to S&B's test you should be fine.

It will be interesting to see if you get the reduction in Silicon in your used oil analysis you are hoping for. How do you know the UOA readings you have are the result of poor filtration as opposed to internal gaskets leaching?

 

[StevieC]

According to Terry the results don't look indicative of an air leak from a gasket etc. Also when I had the engine somewhat apart to put in spark-plugs (have to remove the plenum) I checked all the gaskets for signs of leakage. I also sprayed them all with a generous amount of WD-40 to see if I had white smoke on start up or a miss of some sort. Nothing at all. I even repeated the spray test with the engine running and nothing.

I then did some research on some Hyundai forums and lots of others were seeing the same results in their used oil analysis so it lead me to believe it wasn't a problem but a poor design.

IMO it was definitely an air filtration problem because it uses cotton-gauze media and not paper for the filtration.

We would know by now is USPS hadn't lost my package.

I think that's an excellent setup, Steve. I like the idea of the filter in the engine bay where it's more protected.

It doesn't look water tight but I like to have a large 3/4" hole in the bottom of the filter cover just in case it manages to suck up water or just to let extra dust fall out. The hole won't be large enough to let any sort of meaningful hot engine bay air in.

 

[StevieC]

This one is as water tight as the OEM one. If you drive with water over the hood it will saturate it as it would the OEM but it has kept dry during the heavy rains we had a few weeks ago. (I checked)

Plus it's dishwasher & microwavable safe and BPA free!
