Prothane 8-1906 Motor Mount Insert Kit for Honda Civic Si

The Prothane 8-1906 motor mount insert kit is engineered specifically for 1999+ Honda Civic Si models to reduce unwanted engine movement and improve performance. This innovative 3-piece insert kit utilizes specially formulated polyurethane inserts that work within your existing factory motor mounts to limit excessive engine motion during hard acceleration and shifting.

Key Features:

• Specially formulated polyurethane construction for durability and performance
• Reduces wheel hop and improves traction during hard launches
• Enhances shifting feel and precision by minimizing engine movement
• Works with factory motor mounts—no need for complete mount replacement
• 3-piece insert kit provides comprehensive engine stabilization

By limiting engine movement, these motor mount inserts transfer more power to the wheels while reducing drivetrain slop. The result is improved throttle response, crisper shifts, and better overall performance. Prothane's proven urethane formulation resists oil, road chemicals, and wear far better than rubber, ensuring long-lasting performance improvements for your front-wheel-drive Honda.
