AMS Performance Billet Big Bore Throttle Body Set with Vibrant HD Flanges for R35 Nissan GT-R

The cross-sectional area has been increased by 50% to accommodate power levels exceeding 2000HP.

Maximum Airflow For Your Hungry VR38 Engine

  • Once your power output approaches the 800HP mark, the stock throttle bodies become a hindrance to your intake system’s performance. This restriction becomes more noticeable as power levels rise further. To overcome this limitation, AMS has taken significant measures to enhance the throttle bodies. By enlarging the diameter from the stock 60mm (ID) to an impressive 73.5mm (ID), the cross-sectional area has increased by 50%. This substantial enlargement translates into significant improvements in power gains, especially beyond the 1000HP threshold.

The Largest VR38 Throttle Bodies On The Market

  • AMS, a reputable performance automotive manufacturing company, relies on a team of highly skilled and dedicated engineers to drive their success. These experts were entrusted with the task of creating the largest and most high-performing throttle bodies on the market, specifically designed to complement the Alpha Performance R35 GT-R Carbon Fiber Intake Manifold. With their profound expertise, they achieved remarkable outcomes. Each throttle body housing is meticulously crafted from CNC billet 6061-T6 aluminum, ensuring an abundance of airflow to support power outputs exceeding 2000+HP without any setbacks. The incorporation of enlarged diameter 73.5mm ID bores and low-profile throttle body shafts goes a step further in minimizing restrictions, optimizing performance to the fullest extent.

Throttle Body Upgrade Made Easy

  • Installation of the Alpha Big Bore Throttle Bodies is made simple by utilizing the existing Nissan OEM drive-by-wire electronics. This allows for a straightforward installation process. By swapping out the internal components of your stock throttle bodies with the Alpha Big Bore Throttle Bodies, you can easily complete the installation and be ready to hit the road.

Items that are in stock in the US, either at Bulletproof’s warehouse or at a supplier’s warehouse, are generally delivered within 7-10 days. Special order items from overseas take considerably longer. As a courtesy Bulletproof offers delivery estimates to our customers which take into consideration manufacturer availability and shipping schedule. These estimates represent our best guess based on previous orders from the manufacturer and do not in any way imply a guaranteed delivery window. Many manufacturers work in a “just in time” inventory system and often take 2-20+ weeks to produce an item once an order is submitted. All deliverable items are then sent to our Japanese warehouse. Bulletproof ships a minimum of one full ocean freight container every month from Japan, oftentimes more than one a month. Ocean freight takes an average of 4 weeks. Typically it breaks down to one week in Japan for paperwork and customs, two weeks by boat and one week in US customs/clearance. Due to the wide number of variables between manufacturer and shipping schedules, delivery estimates are simply just that – estimates. We attempt to estimate conservatively and we usually deliver faster than our estimates suggest. It is not Bulletproof’s policy to guarantee delivery time of any special order item, this is impossible for us to do. By ordering you acknowledge that there is no required delivery ETA and an order may not be canceled or altered due to manufacturing or shipping delays, all ETA’s are provided as a best guess only. Please review the full Terms & Conditions.
