If you're looking to enhance your truck's performance without diving into a full engine rebuild, the AFE Silver Bullet Throttle Body Spacer (part number 46-34021) is an excellent upgrade for your GMC or Chevrolet. Designed specifically for the GMC Sierra 2500/3500 and Chevrolet Silverado 2500/3500 models from 1996-2007, this throttle body spacer is engineered to optimize air intake, resulting in improved throttle response and power delivery.
The unique serrated/helix design of the Silver Bullet spacer creates air turbulence in the intake manifold. This turbulence increases air pressure in the combustion chamber, leading to noticeable gains in performance and a more responsive throttle. Unlike traditional helix-only designs, this combination significantly reduces the intake whistle, allowing for a smoother and quieter operation.
Crafted from 6061-T6 billet aluminum, the AFE spacer is not only lightweight but also incredibly strong. Its black anodized finish adds a stealthy look under the hood while providing corrosion resistance. This is a part that not only performs well but also looks great in your engine bay.
One of the standout features of this throttle body spacer is its ability to lengthen the intake track. This design helps to increase the speed of the intake air, which translates to better performance and improved throttle response. Whether you're towing heavy loads or just cruising around town, you'll appreciate the enhanced driving experience.
Worried about installation? Don’t be. The AFE Silver Bullet Throttle Body Spacer uses all factory mounting locations, making the installation process a breeze. It comes with a supplied gasket that ensures a perfect seal, so you can get back on the road quickly and confidently.
Owners of the 2005 GMC Sierra 2500 have reported noticeable improvements in throttle response after installing the AFE Silver Bullet Spacer. One customer said, “After adding this spacer, my truck feels more alive! The throttle response is sharp, and I can definitely feel the difference in power delivery when I’m towing.”
Another 2003 Chevrolet Silverado 3500 owner shared, “Installation was straightforward, and I love the way it looks. Plus, the intake noise is much more refined now.”
Upgrade your intake system with the AFE Silver Bullet Throttle Body Spacer 46-34021 and experience the difference in performance and response for your GMC or Chevrolet truck.
