With my stock airbox I used to get heat soak alot. After removing the divider in the box, plugging the 2nd chamber hole and adding a K&N airfilter I've noticed that I don't get the heat soak nearly as often anymore. Anyone get the same results?

so all u do is cut the middle divider? never heard of this mod

I think it's in your head.

Cutting out that middle divider and NOT removing the "L" shaped intake channel may only be of minimal benefit even in terms of air flow. Hot air would still get in. It's just that now, you're filling a bigger chamber with it.

The thing i dont understnad with the L shape "feeder" is how it is beneficial to remove it. It seems if it guides the airflow towards the intake that it would actually help it. Not disputing the facts just curious about how. I do nned to run some tubing so I can guide cooler air in the box tho. But I've not noticed any bogging after sitting still anymore. I wouldve thought that the 2nd chamber would have added more hot air for the intake to suck in all at once instead of constantly.

I think the best way to get cooler air into the stock intake is with a foil/bubblewrap/foil sandwhich blanket. Cover the radiator, line the airbox, and cover the intake tube. That's when you'll probably notice a difference. Of course, the throttle body is so hot that much of that cold air gets heated back up anyway (I think).

Does anyone have any evidence that removing the "L" air-channel and the wall gives an increase in power and/or any other benefits? When I looked at the airbox I thought the air-channel looked beneficial.

I don't think removing the "L" air channel will gain you any HP as such, but it "might" let the system breathe easier. If you inspect the airbox closely, you'll see that the "L" think leads air directly to the top of the filter. If you remove the divider and leave the "L" in place, you still lead the air directly to the top of the filter.
Imagine being buried in a coffin. You have an air hose ending up just in front of your face. You also have a divider that separates your head from the rest of the space in the "aft" part of the coffin. You're breathing air that comes from the tube. Now remove the divider but leave the tube in place. You're still basically breathing air that comes from the tube because the tube is so close to your face. Now, also remove the tube and let the air come from the hole where the tube came in from the coffin. Now you breathe, but you breathe the air that is also from the rest of the coffin as the tubeless airhole can more easily distribute the air throughout the coffin. (OK, goofy analogy over, )

In case anyone didn't know already, the design of the divider and "L" thing is to use that first chamber as a water trap. Notice how the bottom of the intake horn dips below the bottom edge of the first part of the "L" and there's a slit right there? The "heavier" water falls down that slit and into the first chamber where it drains out those little holes.

More generically, a "particle separator". Not just water, but sand, ash, etc.
