V8 5.7L Hemi Silver Bullet Throttle Body Spacer, Polished suits Ram 1500 DT (2019-2024), 1500 DS (2013-2024) by aFe POWER
This Silver Bullet throttle body spacer produces up to 12 hp and 14 lbs. x ft. torque and is constructed from precision machined 6061-T6 billet aluminum and is designed using a serrated/helix design that creates turbulence in the air flow at the point just prior entry into the engine optimizing the combustion cycle. This turbulence helps the air/fuel charge burn completely providing increased horsepower, torque and improved throttle response. This spacer works with the OE and aFe POWER cold air intake systems.
Serrated/Helix Design
The Serrated/Helix combination design creates intake turbulence in the combustion chamber. This turbulence breaks up the fuel which creates a more complete combustion cycle increasing horsepower, torque and improving throttle response. The Serrated/Helix combination design also reduces intake whistle that occurs with other Helix only designs.
6061-T6 Billet Aluminum Construction
All Silver Bullet Throttle Body Spacers are precision machined from 6061-T6 billet aluminum for light weight, high strength and perfect fit and finish.
Longer Intake Tract
Adding a Silver Bullet Throttle Body spacer lengthens the intake track which helps increase intake air speed increasing performance and improved throttle response.
Fitment with aFe POWER Air Intake Systems
This item will only work with aFe POWER air intake systems: 51-12172, 54-12172, 51-12162 and 54-12162 but will require modification of the intake tube. Refer to the air intake system's instruction sheet for details.
This item will NOT work with any other aFe POWER air intake system.
Overview & Highlights
The aFe Vulcan Series exhaust delivers real power improvements, without the additional droning noise of the conventional Catback Exhaust kits.
Unleash the power and sound of your vehicle with the aFe Power exhaust systems.
Designed and tested in the USA
Sharper throttle response, more grunt under load, and an engine that breathes easier.
Construction & Design
Crafted for strength and longevity, every component of this exhaust is engineered to perform under pressure.
- Material: 304 stainless steel tubing
- Welding: Precision MIG-welded joints for leak-free performance
- Muffler: High-flow straight-through design with tuned acoustics
- Exhaust Tips: Dual 5” black stainless, angle-cut and polished
- Hangers: OE-style bayonet hangers for secure fitment
Performance & Sound
Experience noticeable power gains and a bold, refined sound profile.
The free-flowing design reduces backpressure and enhances throttle response across the RPM range.
- Dyno Proven Horsepower and Torque Upgrades (see product description for the exact gains on your vehicle)
- Deeper, more aggressive tone under acceleration
- Minimal interior drone during highway cruising
- Enhanced airflow for improved efficiency and performance
Fitment & Installation
This cat-back system is engineered for a perfect fit and easy install.
- Installation: Direct bolt-on using included clamps and hardware
- Time Required: Approximately 1–2 hours with standard hand tools. Some exhausts may vary.
Built for the Road & the Long Haul
With a no-drill install and robust materials, this exhaust is ready for everyday driving, towing, off-road use — whatever your rig demands. Backed by aFe’s reputation for quality and engineered for longevity.
WANT MORE POWER?
Pair up your exhaust system with the aFe Power range of Cold Air Intakes. This allows for more, cleaner air to come into your motor which when combined with an aFe Exhaust System, you get some real grunt and increase in Horsepower
FREQUENTLY ASKED QUESTIONS
aFe Power is known for engineering high-performance intake, exhaust, and tuning systems that deliver real, measurable gains. Their products are dyno-tested, precision-built, and trusted globally for quality, reliability, and performance.
Momentum GT and HD intakes use large-volume housings, high-flow filters, and smooth intake pathways to maximise airflow and reduce restriction. This results in improved throttle response, better engine efficiency, and measurable power gains.
Most Momentum intake systems provide gains of 8–20 horsepower and 8–25 Nm of torque, depending on the engine and supporting modifications. Diesel truck applications can see even higher improvements.
The Scorcher is a plug-and-play tuning module that modifies sensor signals to increase boost, optimise fuel mapping, and improve throttle response — giving your vehicle stronger, smoother power delivery.
Typical gains range from 20–60 horsepower and 40–120 Nm of torque, depending on the engine platform. Diesel turbo vehicles see the biggest improvements.
P2M is a throttle response controller that eliminates pedal lag by adjusting accelerator sensitivity. It doesn’t add horsepower but dramatically improves acceleration feel and responsiveness.
These upgraded pipes provide smoother airflow, increased volume, and improved pressure retention over factory plastic or narrow piping — resulting in better turbo response and improved overall performance.
Most aFe exhausts can be installed at home using basic tools in 1–2 hours.
All systems come with hardware, clamps, and clear instructions.
Lift kits, long wheelbases, and rusted factory parts may increase install time.
aFe exhausts reduce backpressure and improve exhaust flow using mandrel bends, high-grade stainless steel, and optimised muffler designs. This results in increased power, better throttle response, and a deeper, more refined exhaust note.
Depending on the system, gains typically range from 5–15 horsepower and 5–20 Nm of torque. When paired with an intake and tuner, total gains can be significantly higher.
Generally, no. Under Australian Consumer Law, a manufacturer must prove that an aftermarket part caused the failure before denying a warranty claim. Intakes, exhausts, and tuning modules typically do not affect unrelated issues.
Many aFe products — especially Momentum cold air intakes and Scorcher modules — can improve fuel efficiency when driven normally by increasing airflow and engine efficiency. Results vary depending on driving style, conditions, and vehicle setup.
We can connect you with a reputable installer through our network, or you can visit our Dealer Network page for approved fitment specialists.
Many aFe products — such as intakes and throttle controllers — are easy to install with basic tools. Exhausts and intercooler pipes may require professional installation for best results and correct fitment.
Oiled and dry filters should be cleaned or replaced according to aFe’s service intervals. Most other components, including exhausts and pipes, require minimal maintenance aside from routine inspection.
Yes. aFe offers manufacturer warranties covering defects in materials and craftsmanship. Warranty terms vary by product but generally include coverage for intake systems, exhaust components, and tuning
