2004 Acura TL Engine Specs: Everything You Need to Know

If you're considering buying a 2004 Acura TL, you're probably curious about its engine specs. The 2004 TL is equipped with a 3.2-liter, SOHC VTEC V-6 engine with impressive performance specs. In this article, we'll look in-depth at the engine specs of the 2004 Acura TL, including horsepower, torque, displacement, and more.

Engine Type

The 2004 Acura TL has a 3.2-liter, SOHC VTEC V-6 engine. This engine is known for its high performance and reliability. It's a popular engine choice for sports cars and luxury vehicles due to its powerful output and smooth operation. The V-6 engine is mated to a 5-speed automatic transmission that comes standard on all 2004 TL models.

Horsepower and Torque

The 2004 Acura TL engine can produce 270 horsepower at 6200 rpm. Its torque output is equally impressive, with a maximum of 238 lbs-ft at 5000 rpm. With quick acceleration and smooth power delivery, this powerful engine makes the 2004 TL a joy to drive.


The redline of the engine is set at 6800 rpm. This means that the engine is designed to operate most efficiently at speeds below the redline. Going over the redline can cause damage to the engine and should be avoided.

Bore and Stroke

The 2004 Acura TL engine has a bore and stroke of 3.50 in x 3.39 in (89 mm x 86 mm). The bore is the diameter of the cylinder and the stroke is the distance the piston travels inside the cylinder. The combination of these two measurements determines the engine's displacement.


The displacement of the engine is 196 cubic inches (3210 cc). This measurement refers to the total volume of all the cylinders in the engine. The displacement of an engine is an important factor in determining its power output and fuel efficiency.

Compression Ratio

The 2004 Acura TL engine has a compression ratio of 11.0:1. This measurement refers to the ratio of the volume inside the cylinder when the piston is at the bottom of its stroke (the "displacement volume") to the volume inside the cylinder when the piston is at the top of its stroke (the "compressed volume"). A higher compression ratio typically results in more power, but can also lead to higher engine temperatures and a higher risk of engine knock.

Induction System

The engine features a Programmed Fuel Injection (PGM-FI) induction system. This system uses electronic sensors to determine the optimal fuel-to-air ratio for the engine, resulting in improved fuel efficiency and lower emissions.


The engine features a Variable Valve Timing and Lift Electronic Control (VTEC) valvetrain, with 4 valves-per-cylinder and a belt-driven single overhead camshaft. The VTEC system adjusts the timing and lift of the valves to optimize engine performance at different engine speeds and loads.

Engine Block

The engine block is made of aluminum alloy with cast-in iron cylinder liners. This material combination provides a lightweight yet durable engine block that can withstand the high stresses and temperatures of high-performance driving.

Cylinder Head

The cylinder head of theengine is also made of aluminum alloy. This material choice provides excellent heat dissipation and improved engine efficiency. The cylinder head houses the combustion chamber and the valves that control the flow of air and fuel into and out of the engine.

Emission Control

The engine is equipped with Electronic Emission Control, compliant with CARB LEV-2 ULEV and EPA Tier 2-Bin 5 emission standards. This system uses advanced sensors and catalytic converters to reduce the amount of harmful emissions that are released into the environment.

Ignition System

The ignition system of the engine is a Direct Ignition System with a Knock Control System. This system uses multiple ignition coils to provide high-energy sparks to each cylinder, resulting in improved engine performance and fuel efficiency. The Knock Control System uses advanced sensors to detect and prevent engine knock, which can cause damage to the engine if left unchecked.

Fuel Economy

The ngine has an EPA estimated fuel economy of 18 mpg city and 26 mpg highway. This is a respectable fuel economy for a high-performance V-6 engine, and is due in part to the engine's advanced fuel injection system and efficient ignition system.

Common Issues and Problems

Like any engine, the engine is not immune to problems and issues. Some common issues reported with this engine include oil consumption, premature timing belt failure, and transmission problems. It's important to have your engine regularly inspected and maintained to prevent these issues from occurring.


The 2004 Acura TL engine is a high-performance V-6 engine that is known for its power, reliability, and efficiency.
