The new Z1 Motorsports 75mm Throttle Body Upgrade Kit for VQ35DE single throttle body engines is a simple bolt-on upgrade for naturally aspirated and forced induction applications. With 5mm larger throttle plate you can expect to see power increases carried throughout the engines RPM range while making the engine more responsive during acceleration. By re-clocking the throttle body to lower the harness connector we were able to improve under hood clearance when compared to other aftermarket throttle body kits. The included throttle body is a Genuine OEM Nissan Hitachi unit, promising the very same reliability and functionality as the original throttle body.

• No Tuning Required!
• Improves Power and Response
• Direct Bolt-On Installation
• High Hood Clearance
• 5mm Larger Than Stock

• Free Shipping to the continental US!

Select to add the optional silicone elbow at a discounted price if installing with a Z1 MSpec Street or Race intake which has a straight end from the pipe to the throttle body, this is a necessary part for that install. 
This silicone elbow can also be installed onto a rigid Z-Tube like Z1 offers but is not compatible with the oem Z-tube .  Available in RED, BLACK, and BLUE.  The coupler may work with other 3" intakes though we have not confirmed all custom fitment applications.
