Very true. But the stock filter flow's as well as the budget will allow. It K&N flows better than stock, the more flow, the more power.

You can make more power with lower restriction exhaust, why does the factory not put the better flowing exhaust on the vehicle? The reason is similiar to the paper vs. cloth air filter.

I think your answer is in the read below. As far as the Exhaust goes... It has to do with a ton of other factors such as emissions,etc and other things that I'm sure F5 and our other resident HUMMER Engineers can explain when they drop by and read this post.

Your low restriction High Flow Filters Like K&N only flow so long before the oil in the gause starts to clog and slow down flow.

I use to use a K&N on my 86 Supercharged Corvette. After several months of driving it would start to clog up. I switched back to paper rather then go thru the hassel of cleaning it all the time. Besides...How much dirt does the K&N pass into your motor In it's Hi Flow mode..???

We could go back and forth here as some people like Chocolate and some Vanilla... So..as long as your happy with yoor K&N..that's all that counts.

They do clog and you have to keep an eye on them.

I plan to use one and if I see any ill affects, off it goes.

At any rate - I thank you for the posting and it is great to see everyone on the board keeping an eye out for everyone else!!

It's not that it clogs, it's that it's also a poor filter. It's no big deal if you're not into long term ownership. On that line of thinking, why not just ziptie a chunk of old t-shirt over the opening?
