Product Description

By popular demand, Accufab introduces the ultimate bolt-on throttle body for the 2011-2013 Mustang 5.0 GT or Boss. This is the largest diameter throttle body to fit the stock OEM Mustang 5.0 intake manifold and Boss 302 intake manifold. It measures 84.5mm and flows 32% more air flow than the OEM throttle body, and more than any other new 5.0 throttle body on the market.

Accufab's quality is second to none - this throttle body is CNC machined from 356 billet aluminum, and the exterior is polished to an eye-catching finish. The shafts are also CNC machined from stainless for durability and quality, with brass blades and the highest quality bushings, bearings and screws. Manufactured in the USA.

There are no adapters or modifications required, the unit comes with a new Ford Throttle Body motor and is pre-calibrated at Accufab prior to shipment. Bolt it on and go. This Accufab Throttle Bodies specifically designed for use on the 2011-2012 Ford Mustang GT. It will also fit the new Boss 302 manifold.

Technical Notes- The inlet opening on the throttle body measures 4.00-inches (OD) in diameter, and will require a step-hose from 4.00-inches reduced down to 3.50-inches (ID) if you plan to use the OEM air cleaner inlet tube. Most aftermarket “cold air kits” measure 4.00-inches (ID) and should fit perfectly.

5 Stars   Quality piece
By on 6/13/2015
Went on easy and runs great. Installed with the Airaid cold air intake. The car appears to have more mid range power and torque as evidenced by the car being much looser when winding it up ??. Better tires needed !

Yes, I would recommend this item to a friend!

Excellent quality throttle body from Accufab.I saw some of the reviews about the price,but It is worthy,better throttle response.For anybody that has Steeda Cold Intake you need to buy from 3.5 to 4 inch connector.Very easy to install and to me is worth the money

Yes, I would recommend this item to a friend!

5 Stars   Instant throttle response
By on 7/19/2014
Added it on with a boss intake and definitely felt a huge gain.Throttle response is instant and car revs a lot smoother. My only complaint was the throttle body was way too big to fit with my steeda cold air intake. I needed to buy a 4" to 3.5" silicone reducer.

Yes, I would recommend this item to a friend!

5 Stars   Huge performance improvement
By on 4/10/2015
I bought this after first adding the Steeda CAI, JBA long tube titanium ceramic headers with 3" hi flow H -pipe and the Steeda tune. WOW what a difference!! The engine spins up instantly to 4K with minimal effort and screams all the way to redline much faster than before. Highly recommended if you already have the CAI and headers.

Yes, I would recommend this item to a friend!
