AMS Performance 2009+ GT-R R-35 Alpha CNC Big Bore Throttle Body Set w/ Vibrant HD Flanges - ALP.07.08.0006-4

At around 800HP, your stock throttle bodies become a restriction to the intake system. The negative effects of this bottleneck are exacerbated exponentially as power increases from there on. By enlarging the diameter of the throttle bodies from the stock 60mm (ID) to a massive 73.5mm (ID), we increased the cross sectional area by 50%. This provides much improved power gains – especially over the 1000HP mark.

• 73.5mm throttle bodies – the largest OEM-style on the market

• 22.5% increase in diameter, 50% increase in cross sectional area

• Increased mid-range and top end power

• Does not adversely affect low-end power

• Available with 3″ AMS QuickClamp™, 3″ Vibrant HD Clamp, or 3″ Standard (Silicone Hose) Flanges

The Largest OEM-Style VR38 Throttle Bodies On The Market

Since we are a true performance automotive manufacturing company, we employ a team of highly qualified engineers with years of motorsports experience. Our engineering team was given the task of designing the largest, best-performing throttle bodies on the market to feed our AMS Performance R35 GT-R Carbon Fiber Intake Manifold, and they delivered! Each CNC billet 6061-T6 aluminum housing was specifically designed to provide enough air flow to support 2000+ HP without issue – implementing enlarged diameter 73.5mm ID bores along with low profile throttle body shafts to minimize restrictions even further. AMS Big Bore Throttle Bodies utilize your existing Nissan OEM drive-by-wire electronics. Simply swap out the internal components from your stock throttle bodies and you are ready to go.
