What is recommended? The HX35 inlet is 4" so I would like one with a 4" flange if possible. I thought about getting one from the Cummins series, but I think that may be too large. Thanks!

01-08-2011, 05:57 PM #1Hey, I am looking to modify my 603 air cleaner system, I am going install my HX35 Turbo and I want to go ahead and install a larger filter. I am thinking that I will remove the current air filter box but keep the compartment to reduce taking in heat.

Keep it. You have a really good air cleaner with 630 CFMs. Making modifications or going aftermarket can possibly reduce your CFMs.

If you still choose to replace it, avoid all "performance" filters. Use only good paper ones.

Ive had one on my 300sd since I got it, I also have one on my Volvo. B
There are a few nice paper clamp ons out there but good luck finding one that will fit under your hood. The cummins guys use a huge one.

I like and use the afe double guard filters. I have one on my diesel bronco that regularly sees fine dust and dirt and my intake and intercooler are spotless on the inside.

How many times do they run the Baja between engine rebuilds? How many of those engines get used more than 2k miles/year? How many of those engines operate reliably for 20+ years without major repairs?

<<The scurry along little boy, only adults are allowed to debate.>>
Why do you feel the need to act like this, FI, JJFF, OM617 or the other screennames you use due to getting banned from other forums? Don't you think you might want to not act that way & get things done productively?
Do you have any scientific data to back up your statement about paper vs. cleanable filters?
As to your knowledge in other areas, you are immensely helpful, but your childish like attitude is not needed.
In a really dusty environment, an oiled filter MAY catch more of the fine particulate that you would see in desert racing.
Again, PLEASE inform us with some form of scientific data so that we can LEARN. I believe that's what this forum is all about.

Quote:In a really dusty environment, an oiled filter MAY catch more of the fine particulate that you would see in desert racing.Incorrect. Oiled filters by nature have very large pores. Unless the filter is extremely large for the engine (99.99% of the time people use one much too small) then the mass of the dirt simply blows straight through it. Who cares about fine dust when the pores allow large debris into the engine?
K&N took a screen door, hacked it up, covered it with gauze, coated it with oil and put it on the market as a "filter". Others wanted in on the extremely high profit margin so they copied the idea and continue to push it on gullible consumers.

Stock paper air filter
$10
Lasts over 1 year with no maintenance needed in that time, can last several years if a restriction gauge is used
Filters very well
Is not a restriction to power
10 year cost= ~$100
K&N filter
$55
Requires a "recharge" oil kit, $15
Requires frequent cleaning
Becomes restricted very quickly
Filters very poorly
Doesn't actually increase performance, just noise
10 year cost= $85 (2 recharge kits)
Total savings over 10 years= $15.
So, what is K&N's advantage again? Nothing. There is no increase in power, a major decrease in filtering quality and a major increase in maintenance. Skip eating out for dinner once and you'll have saved more than you would after 10 years with a K&N.

Where does the 616's oil bath filter place? I'd think it's better filtration than a K&N, but more hassle than a pleted paper.

Only problem is they have to be matched closely to your engine's airflow. Otherwise you get poor filtration and/or high oil consumption.

They don't. The engine doesn't care about the air filter, its power is limited by fuel. The only thing that really changes is the noise, which most people perceive as an increase in "performance".
