I e-mailed Twin Air about the availability of their aluminum air filter cage.
Here's their response....
"We can get the kit if you want - # 158041c. MSRP is 124.95. It will take @ 4 weeks until we receive the kit."
This kit comes with the air filter, so it is not a bad price.
The stock set up is an accident waiting to happen.
Group buy any one?
