This 370z/g37 breather hose set gives your VQ37VHR or VQ37HR-swapped build a clean, functional solution for routing PCV breather lines when running an aftermarket intake. Stock rubber hoses don’t play well with most cold air or short ram setups — this silicone kit fills that gap with heat-resistant construction and a complete hardware package so nothing’s left dangling or zip-tied.

Available in black or blue to match your engine bay aesthetic.

Kit includes:

• (2) Aluminum 90° hose-to-filter adapters for secure, leak-free connections at the valve cover ports
• (2) High-flow velocity stack air filters to vent crankcase pressure cleanly without restriction
• Silicone construction handles elevated underhood temps without cracking or collapsing over time
• Fits the Nissan 370Z and Infiniti G37 with the VQ37VHR engine platform
• Designed specifically for use with aftermarket intake systems where factory PCV routing is no longer viable

A straightforward fix for one of the more overlooked details in a VQ37 intake build.
