If you own a 5.7 Hemi engine, understanding how to choose the right spacer is essential for optimizing your vehicle’s performance.

Benefits of a Throttle Body Spacer

Additionally, I noticed a slight improvement in fuel efficiency, which is always a plus. If you enjoy taking your vehicle on long drives or off-roading adventures, a throttle body spacer can enhance both performance and driving experience.

Material Considerations

When I was searching for a throttle body spacer, I quickly learned that the material used can significantly affect performance. Most spacers are made from either aluminum or plastic. Aluminum spacers tend to be more durable and can withstand higher temperatures, while plastic options are often lighter and provide better thermal insulation.
