This Performance Air Intake adapter has the function to adapt the biggest high flow air filters on the market. No other system will allow you to adapt several different styles as the one you see on this page. Our Intake adapter has the same common bolt pattern as you would find on 90% of the Harley Davidson aftermarket filters. With this style of air intake adapter you'll be able to improve the performance of your Star Stryker and keep your ride looking different then the next guy. To complete the kit please choose a air filter from our selection. To further separate our product from the rest, there's also no other system that completely covers the throttle body and helps hide the wires, hoses and cables like what is offered .
