By mounting the AVO Power filter in the inner fender guard, you can be sure of getting cold air to your engine! AVO uses a washable and fully re-usable hi-flow bolt-on filter system that includes the mounting flanges and 2 silicone hoses with a 45 deg stainless connecting pipe. It is truly simple to install on your own, and is a good, cheap power-adder that works well with stock or modified setups. If you are seeking maximum power, this is the way to flow.
