Acura J37A Engine Specifications

The Acura J37A is part of Honda's J-series V6 engine family. It has a 3.7-liter displacement and uses a naturally aspirated petrol configuration with electronic fuel injection and VTEC valve technology.

Here are the general specifications of the J37A engine family:

Specifications can vary between J37A engine versions and model years. Confirm the exact engine code before ordering.

Compatibility / Fitment Notes

The Acura J37A engine family was installed in several Acura models. However, not every J37A variant is a direct replacement for every vehicle equipped with a 3.7-liter engine.

The following applications are associated with the J37A engine family:

Important fitment considerations:

Before purchasing an Acura J37A replacement engine, verify:

• Original engine code and vehicle VIN.

• Vehicle make, model, and production year.

• Front-wheel drive or all-wheel drive configuration.

• Transmission compatibility.

• Engine mounting points and accessory arrangement.

• ECU, wiring harness, and sensor compatibility.

• Intake and exhaust manifold configuration.

• Emissions equipment and regional requirements.

A J37A1, J37A2, J37A4, or J37A5 should not automatically be considered interchangeable simply because all four belong to the same engine family.

Engine Configuration

The Acura J37A features a 60-degree V6 configuration with a single overhead camshaft (SOHC) cylinder head design and 24 valves.

Its VTEC valve technology helps optimize valve operation across different engine speeds. The engine also uses an aluminum engine construction and electronic fuel injection.

This configuration was developed to deliver the power characteristics expected from Acura's larger luxury SUVs and performance-oriented passenger vehicles.

Engine Displacement

The J37A has a displacement of 3,664 cc (3.7 liters).

Its bore measures approximately 90 mm, while the stroke measures approximately 96 mm. This displacement provides the engine with its larger-capacity V6 characteristics compared with Honda's smaller J-series engines.

Fuel Type

The Acura J37A is designed to operate on petrol (gasoline).

It uses an electronic multi-point fuel injection system to deliver fuel to the engine's cylinders. Fuel requirements should be checked against the original vehicle's owner's manual and market-specific specifications.

Aspiration / Induction

The J37A is a naturally aspirated engine.

Unlike turbocharged or supercharged engines, it does not rely on forced induction to increase the amount of air entering the cylinders. Instead, it uses its 3.7-liter displacement and naturally aspirated V6 configuration to produce its factory-rated power.

Power Output

Depending on the specific engine variant and production year, the Acura J37A produces approximately 300–305 horsepower.

Examples include:

• J37A1: Approximately 300 hp.

• J37A2: Approximately 300 hp.

• J37A4: Approximately 305 hp.

• J37A5: Approximately 300 hp.

These ratings are factory specification references, not guaranteed performance figures for an individual used engine.

Torque

The J37A engine family produces approximately 270–275 lb-ft of torque, depending on the engine version.

For example, the J37A1 produces different torque ratings across its production years, while the J37A4 is rated at approximately 273 lb-ft.

Torque specifications are important when matching a replacement engine to the original vehicle's drivetrain and transmission requirements.

Years / Generation

The Acura J37A engine family was used in selected Acura vehicles from approximately 2007 through 2014.

The individual engine codes have different application periods:

• J37A1: Second-generation Acura MDX.

• J37A2: Acura RL.

• J37A4: Fourth-generation Acura TL SH-AWD.

• J37A5: Acura ZDX.

When ordering a replacement engine, use the exact engine code rather than relying only on the vehicle's model year.
