4500 Tuner / Engine Builder Open Spacer Kit

The 4500 Tuner / Engine Builder Open Spacer Kit is a top-tier product designed for those seeking to enhance the performance of their engines. This comprehensive kit includes a set of three open spacers, crafted with precision to provide optimal performance. Wilson Manifolds, known for its high-quality products, has set the standard in NASCAR NEXTEL Cup racing with these open spacers, making them a sought-after choice for any engine application.

Product Specifications and Benefits

This kit is tailored for 4500 carburetors and comes with a variety of spacer heights to cater to different tuning needs. The open spacers are available in .5", 1", 1.5", and 2" heights, ensuring that you can find the perfect fit for your engine. The benefits of using these open spacers are numerous. They increase plenum volume, allowing for a more efficient air/fuel mixture distribution. The design of the open spacers also moves the throttle blades away from the roof of the runners, making it easier for the mixture to enter the runners and improve overall mixture quality. This results in a noticeable increase in mid-range and top-end horsepower.

Practical Applications and Target Audience

Whether you're a professional tuner or a DIY enthusiast, the 4500 Tuner / Engine Builder Open Spacer Kit is an essential tool for any Dyno room or track tuning session. Its ability to add mid and top-end power, increase plenum volume, and improve mixture quality makes it a must-have for anyone looking to push their engine to its limits. The kit's versatility and precision in tuning make it ideal for a wide range of applications, from street rods to racing vehicles. With Wilson Manifolds being the only manufacturer to offer multiple heights for 4500 carburetors, this kit stands out as a reliable and high-performance solution for engine builders and tuners alike.
