The Z1 Motorsports Silicone Replacement Intake Couplers replace the faliure prone factory rubber intake couplers on all VQ35DE equipped Infiniti G35's. Over time the factory couplers crack, creating harmful intake leaks that result in lean running conditions.

These are the last intake hoses you will ever need. Unlike conventional stock rubber couplers that deteriorate over time, dry rot, and ultimately crack this silicone will stay soft and never degrade. Best of all they cost far less than new OEM rubber hoses!

Z1 Motorsports offers a full line of silicone hoses for the G35 that will be the last hoses you will ever have to purchase. There's no reason to consider anything else.

Available in Black, Blue, and Red.

Intended for use with OEM intake ONLY.


  • 2003-2007 Infiniti G35 Coupe
