ISR Performance Silicone Air Intake Tubes for the Nissan Z and Infiniti G chassis with HR motors are made of high grade, heat-resistant silicone to prevent increased temperatures in the intake caused by excess heat in the engine bay. Preventing excess intake temperatures will allow for more cool air, in turn increasing horsepower and providing better performance.

 These will fit both VQ35HR and VQ37VHR, theres some slight differences in PCV routing between the different iterations of HR (350z, G35, etc.) and VHR as well, so some slight trimming may be required on the PCV inlet depending upon the customers exact application. You should not need to trim the throttle side however, it will be a bit snug when installing as the factory routing of the intake tube, and positioning of the PCV, MAF, and Throttle make for a relatively tight fit. You do need to squeeze the hose and work it around the throttle to have it fit properly

You can see an installation of the product here, no trimming of the throttle or MAF side is required.
