Airbox top off with K&N Filter

[kope]

i wouldn't remove the top of the air box because then the filter will be drawing in hot air from the engine bay instead of pulling the air in thru the fender well.....so the little restriction relieved would most likely be lost from the hotter air.

You talking about the box near the trottle body? What size cap do u need? I got the K&N filter just to cheap rite now to buy a CAI. The sound would be cool.

2.5" cap...I squeezed on a 2" though.

Good point, didn't think about that. How about removing or "swiss cheesing" the bottom to get cooler air through fender well? We do this on the B Body Chevys.

Keep your air box closed so it gets the most out of the cold air from the fender.

I can't find a cap that will fit. Where did U get the cap from? I got bored today and wanted the silencer off.

with the k&n plus the cut out in the lid made it a little louder and it seemed to pull a little better on the highway wide open throttle

green monster, got mine at lows in the plumbing section by all the pvc pipe fittings. I got a 2" cap and slit each side for it to open wider, then secured it with a hose clamp.

Hockey Puck mod....for B Body cars. Too big for the Tahoe I think.

We put a puck in place of a piece we take out.
