AIR Filter Question...

not sure but you can run 2 airfilters instead of just 1, this will reduce restriction, or you can buy a marine engine cone filter they are just like K&N filters (cotton/steel mesh/oil)

 

Fleet air make a k&n like filter. I've never used one so i can't say how well they work.

 

I have donaldson premium filter elements in my breathers. Visualably they look like much nicer elements then the usual paper ones. Can't say if they help much for mileage... Did too many mods at the same time.

 

I'm using a Cleer-Air filter in my Volvo. It's like a K+N style filter. I've had it in for a month. So far it seems fine. I work in a dusty environment hauling sawdust and wood chips.

 

There are lots of test results out there that prove the washable filters let threw dirt and are not good for your engine. You might want to ask your engine manufacturer what they think and how long your warranty will be if you use it. When the engine is taken apart, The wear will be evident and any warranty will be denied. If you have a washable filter remove the piping from the turbo inlet, and take a damp white towel, reach in and wipe the inside of the pipe. Any dirt will destroy your engine, the lines the rings the bearings, everything, it works with the oil turning it into lapping compound. Using those filters in any vehicle is dumb, but I only worked on them and saw the damages done. Using them is good for the mechanics economy. Just a thought! and if someone tells you they have oil analysis that shows no silica I would call them a liar and run from there opinion.

 

I found the test results but I do not know how to make the link so you have to type it your self. Google ISO 5011 Duramax air filter test report. If you print it out and then when someone tells you they know about these fancy air filters, you have the truth to show them. I personally have seen engines completely destroyed from dirt in the intake air, and I mean totally everything worn out top to bottom and everything in between.

 

Not to knock the pruported ISO 5011 test that Spicer ran, but that has been debunked numerous times on other forms since it came out:

I'll summarize some of the errors, ommissions, and cheats.

For one thing, it was not apples to apples comparison - they failed to disclose that the part numbers they were comparing were not for the same application.

Why is it that the capacity, effificency, and fine dust test on 7/13 of the AFE use a prt number 72-90008 rather than the 73-10062 filter that was used in other tests?

Why was the AC Delco used as a benchmark, yet there is no test data for it?

Why were some tested with fine dust, and some with coarse dust? Shouldn't they all be tested the same?

The report says that they conducted testing on three different days - 7/6, 7/12 and 7/13). Were new K&N filters used in each test or was one K&N cleaned and reused?

They claim the test costs $1,700 per filter, and that Testand (right down the road from FRAM) conducted the test, yet FRAM was not tested.
