Engineered for enthusiasts replacing the factory F-Series engine with a Honda K20 or properly configured K24 engine, the Innovative Mounts 99352 provides the specialized mounting components necessary to position and secure a compatible K-Series drivetrain within the Accord engine bay.

The 1990–1993 Honda Accord is a popular platform for Honda performance enthusiasts thanks to its durable construction, practical chassis design, and extensive engine swap potential. Upgrading to Honda's K-Series engine platform opens the door to increased horsepower, improved torque, modern engine management, and extensive aftermarket performance support.

However, installing a K-Series engine into a fourth-generation Accord requires specialized mounting components because the factory F-Series engine and transmission mounting system is not compatible with the replacement drivetrain.

The Innovative Mounts 99352 addresses these requirements with a purpose-built steel conversion mounting system consisting of three primary engine and transmission mounts and two specialized mounting brackets.

Designed for compatible Accord chassis originally equipped with either manual or automatic transmissions, the 99352 provides the mounting foundation for a K-Series conversion using a compatible hydraulic manual transmission.

The kit incorporates Innovative Mounts' performance polyurethane bushings, engineered to reduce excessive drivetrain movement during acceleration, deceleration, and shifting. Compared with conventional factory rubber mounts, these firmer bushings help maintain more consistent engine and transmission positioning under load.

Featuring CAD/CAM-engineered components, stress-analyzed construction, and Innovative Mounts' no-tear polyurethane bushing design, the 99352 is an excellent solution for naturally aspirated K20 builds, turbocharged K24 projects, street performance applications, and dedicated motorsport vehicles.

Important: The Innovative Mounts 99352 is a K-Series engine conversion kit for 1990–1993 Honda Accord CB chassis. It is not a direct replacement for the original F-Series engine mounts. A compatible K-Series engine-side mounting bracket and additional swap components are required.

Available Polyurethane Bushing Hardness Options

75A – Black – Street / Performance

The softest available bushing option for the 99352.

Recommended for street-oriented Accord conversions where improved drivetrain stability is desired while retaining some vibration isolation.

Manufacturer horsepower guidance: approximately 250–400 HP.

85A – Grey – Performance / Race

Provides increased drivetrain rigidity for modified engines, aggressive driving, and competition applications.

Manufacturer horsepower guidance: approximately 400–500 HP.

95A – Red – Extreme Race

The stiffest available polyurethane option, intended for high-output engines and dedicated racing applications.

Manufacturer horsepower guidance: 500+ HP.

These horsepower ranges are manufacturer bushing selection guidelines rather than guaranteed load ratings or minimum horsepower requirements.

Important: Increasing bushing hardness generally increases noise, vibration, and harshness transmitted into the vehicle cabin. The 75A option is typically the most appropriate starting point for a street-driven Accord conversion.
