Overview

This Rtunes Racing threaded hose adapter connects a 5/8" threaded port to a 1/2" inside diameter hose. The male threaded end screws into the port, the hex body allows easy tightening with a wrench, and the included black O-ring seals against the mating surface for a leak-free connection. The tapered, multi-ridge barb grips the hose securely.

This Rtunes Racing air intake kit is built for your vehicle. Mandrel-bent aluminum piping and a high-flow, washable filter replace the restrictive factory setup for better airflow and sharper throttle response.

The kit includes the mounting hardware, hoses, and couplers shown in the photos and installs using the factory mounting points.

• Increased airflow — a less restrictive design than the stock air box, for better throttle response throughout the rev range.
• Aggressive sound — a deeper, more pronounced intake growl every time you get on the throttle.
• Built to last — mandrel-bent aluminum piping paired with a high-flow, washable, reusable filter, engineered for a precise, secure fit.
• Complete kit — includes the mounting hardware, hoses, and couplers shown in the photos.
• Easy install — most kits bolt on in 30–60 minutes with basic hand tools, using the factory mounting points.
