The stock intake tube also includes a splash container to partition any water away from the intake that makes it past the MAF. You don't get that with the aftermarket tubes.

At the strip or for a street car, K&N is fine, off road severe duty conditions, your stock filter is your friend. Don't bother posting about the Baja 500, those engines aren't expected to go 100,000 miles.

Now that makes sense! I was considering the K&N myself, but I think I'll stick with stock!

Thanks for the info...

I was searching for that old post that showed filter performance for the stock H2 filter, but can't find it.

There were plenty of post about good stock filter performance based upon oil analysis and you'll find many post about vibration, noise, and no change in mpg when using aftermarket filters and filter + tube combos.

I had a "stright pipe" and K&N cone filter on my Camero a long time ago.

It took out the box that had the water baffels ect.

The mass air had rust all over the springs that held the wires and F'ed it up...no telling how long it was running rich or lean....

So would it be better to run stock air filter with aftermarket exhaust and a programmer then with an air intake?
