What is this elbow made of? Is it black rubber or metal? It's probably rubber, and held on with a hose clamp, right?

Definately rubber.

probably rubber or plastic. if it was metal they would prob make it all shiny.

yep rubber, china atv/bikes use rubber on those curved manifolds

Excellent. I've made a homebuilt air filter from a tuna can and a plastic lid that says "Frito Nacho Cheese Dip". It's super cool, but the airflow just isn't quite right. It would be easier to just clamp one of these babies on, and it's affordable enough.

Doubt it adds hp though, i have found cheap ones to be more restrictive than the stock...

Extra horsepower is always nice, but that's not really what I'm looking for. The stock air filter on my engine is a piece of crap. All I need is something that will hold together and actually keep dirt out.

Will do the job then, i bought one and got damaged in mail, damage easy... what engine are you using it on?

Harbor Freight 2.5 hp. I need to measure the outside of the carburetor to make sure I get the right size elbow.

Your going to need a manifold to hold that filter on.

I made this with the original air filter box. Not sure if it is the same on the 2.5 as the 6.5

I just starting cutting with a hacksaw until I got it right. it's not perfectly round but a clamp filter just like your clamped and sealed with no problems.
