steel mesh screen instead of filter .
FWIW, I bought an old school Harley that had a velocity stack on it with a mesh screen. I pulled the intake manifold off the bike at one point and noticed that both cylinder head intake ports were a bit beat up from how ever many miles of debris getting sucked past the screen. Needless to say, I now run a more traditional air cleaner setup utilizing a K&N air filter. Just something to consider.
Missed this earlier:
Honestly, I just figured that if I'm gonna be mean to my engine and make it suck up dirty air, that the oil would be quicker to contaminate over time.
I think its' a gut feeling thing...
What's your take on it?
Haha not at all :-) Just giving you a hard time

Not doubting that all.
I should at some point post a picture up of my ghetto *** shield.
It blocks everything from below - which is most of the dirt/debris would originate.
It also blocks a little bit of the sides, for extra protection. The only place it truly gets most of its' air, is from above, near the radiator.
On the *off chance* something larger does get through, the wire guard will stop it.
Am I dirt proof? Hell no.
Am I dangerous pebble/object proof? I could say with confidence that I am.
I have inspected the impellor and throttle body blade itself after a thousand miles running this way (I know, a thousand miles isn't saying much):
The volute is clean, the impellor is clean
The throttle body blade is clean, with no scratches.
"This guy is in denial" - fine, I get it. To each their own.
Nothing will beat a full fledged filter. Period. But you can get pretty damn close.

Birds not good, Ice rarely a problem, Water not a problem ....they fly in the rain all the time but none of this has anything to do with a vehicle that travels at ground level anyway.
Dust will kill a cylinder in no time at all, I had a fresh piston and rings in an dirt bike and it only lasted few hours of trail riding because the air filter boot ripped when I put it together and I missed it. It still ran good but I could tell the power was down and when I pulled it apart it looked like the piston and cylinder wall had years of run time not hours. I know a car won't see that type of environment on the street but dust will certainly shorten the life of the engine.

nah I'm mostly playing. Ive only killed 1 piston in i dunno how many builds and combos in the last 3 years. BUT i did just get some eighty dollar chinese 120lb squirty bois that are basically guaranteed to kill something, so look for an engine internals part out soon 
I'll admit I did hurt a JY 5.3 recently, Didn't even get much further than the initial tune. It had a 6-71 blower on it and I just had the blower rebuilt, It was supposed to make about 8lbs-10lbs of boost with the pulleys I ran, It made 14lbs at about 2,800rpm and butted rings and popped a ring land. It didn't hurt anything other than the one piston so I'm just going to toss in a used piston and rings and run it again. Lesson learned = Start the tune on E85 and not 93.
