Engineered to improve drivetrain stability, reduce excessive engine movement, and provide increased durability over aging factory mounts, this performance engine mount is an excellent upgrade for daily-driven and modified K-Series vehicles.

Factory Honda and Acura engine mounts are designed primarily to isolate engine vibration and maintain everyday driving comfort. Over time, original rubber and hydraulic mounting components can deteriorate, crack, leak, or separate, allowing excessive engine movement during acceleration, deceleration, and gear changes.

Innovative Mounts addresses these limitations with a performance-oriented replacement mounting system featuring specially engineered polyurethane bushings. By reducing the compliance associated with factory-style mounts, the Innovative Mounts 10721 helps maintain more consistent engine positioning under load, improving drivetrain response and reducing unwanted movement during spirited driving.

The upgraded polyurethane design also helps control drivetrain movement that can contribute to wheel hop during aggressive acceleration. Unlike fluid-filled factory mounting components, the performance polyurethane bushing provides a firmer connection between the engine and chassis.

Each mount is CAD/CAM designed and stress analyzed to provide dependable fitment and durability. Available in multiple polyurethane bushing hardness options, the Innovative Mounts 10721 allows enthusiasts to select the appropriate balance between vibration isolation and drivetrain rigidity for their specific application.

Whether you're replacing a worn passenger-side engine mount on your Accord K24, improving drivetrain stability in your Acura TSX, or preparing your K-Series engine for additional horsepower, the Innovative Mounts 10721 provides the durability and performance needed for a more responsive driving experience.

Installation Notes

1. Verify Vehicle Compatibility: Confirm that the vehicle is a compatible 2003–2007 Honda Accord 2.4L or 2004–2008 Acura TSX equipped with a supported K-Series engine.

2. Confirm Mounting Position: Innovative Mounts 10721 is designed for the passenger-side (right-hand) engine mounting location.

3. Verify OEM Mount Compatibility: Confirm that the original mounting configuration matches one of the manufacturer's specified OEM references.

4. Support the Engine and Transmission: Properly support the drivetrain before removing the factory passenger-side engine mount to prevent unexpected movement or damage.

5. Remove the Factory Engine Mount: Follow the appropriate Honda or Acura service procedures when removing the original mounting assembly.

6. Inspect Factory Mounting Locations: Check the engine bracket, chassis mounting points, and surrounding components for damage, corrosion, or excessive wear.

7. Install the Innovative Mounts Assembly: Position the replacement mount according to the manufacturer's instructions, ensuring correct orientation and alignment.

8. Inspect Factory Hardware: Examine original mounting bolts and fasteners before reuse. Replace damaged or excessively worn hardware.

9. Align the Drivetrain: Ensure the engine and transmission are properly positioned before final tightening to prevent unnecessary bushing preload.

10. Torque Mounting Hardware: Tighten all fasteners according to the applicable Honda/Acura and Innovative Mounts specifications.

11. Verify Component Clearance: Check clearance around the engine, transmission, intake system, exhaust components, and surrounding chassis components before operating the vehicle.

12. Select the Appropriate Bushing Hardness: Choose the polyurethane durometer that best matches the vehicle's horsepower level, intended use, and acceptable vibration.

13. Expect Increased Engine Vibration: Performance polyurethane mounts generally transmit more engine vibration into the chassis than factory rubber or hydraulic mounts. Higher-durometer bushings typically increase vibration further.

14. Inspect Other Engine Mounts: If the original passenger-side mount is worn or damaged, inspect the remaining factory engine and transmission mounts for deterioration.

15. Inspect After Installation: Recheck mounting hardware, drivetrain alignment, and surrounding clearances after the initial driving period.

16. Professional Installation Recommended: Installation by an experienced Honda/Acura technician is strongly recommended.

17. Confirm Fitment Before Bolting Down: Innovative Mounts states that mounts showing installation bolt impressions cannot be returned or exchanged. Verify all mounting requirements before installation.
