The James Manifold Spacer Kit includes all necessary components to replace the original manifold spacers with high-performance alternatives.

First and foremost, the James Manifold Spacer Kit enhances the engine's breathing capabilities. The increased clearance allows for a more efficient gas flow, resulting in better combustion and increased power output. Moreover, the improved exhaust gas scavenging leads to a more complete combustion process, reducing exhaust emissions and improving fuel efficiency.

Additionally, the new spacers contribute to a more visually appealing engine compartment. The increased clearance between the manifold and the cylinder heads creates a more even gap, resulting in a cleaner and more symmetrical appearance. This is an excellent upgrade for those seeking to restore their classic Harley-Davidson motorcycle to its former glory or for those looking to give their bike a subtle performance enhancement.

Installation of the James Manifold Spacer Kit is a straightforward process. The kit comes with clear and concise instructions, making it an ideal DIY project for the dedicated Harley-Davidson enthusiast.
