Mitsubishi Cylinder Heads Guide: Everything You Need to Know

When it comes to Mitsubishi engines, one key component stands out for performance, durability, and reliability: the cylinder head. This essential part plays a crucial role in your engine's functionality, as it contains the combustion chambers where the magic of fuel burning happens. If you're looking to learn more about Mitsubishi cylinder heads, especially those for popular engines like the 4G15, 4G61, 4G37, 4G63, and G63B, you've come to the right place. Let’s dive into what makes each Mitsubishi cylinder head unique and what you need to know to make the best choice for your engine.

The Role of the Cylinder Head in Your Mitsubishi Engine

Before diving into the details, let’s start with the fundamentals. In a Mitsubishi engine, the cylinder head sits at the top of the engine block, sealing off the cylinders and combustion chamber. This essential component holds the intake and exhaust valves, fuel injectors, and spark plugs, playing a vital role in the engine’s performance. In short, it’s where the engine draws in air and fuel, compresses it, ignites the mixture, and pushes out the exhaust gases.

The quality of your cylinder head impacts your vehicle’s overall performance. Mitsubishi, known for its engineering excellence, designs cylinder heads that deliver efficiency, durability, and power. Whether you own a classic Mitsubishi or a newer model, understanding these components can help you maintain and even boost engine performance.

Each of these cylinder heads has unique characteristics suited for specific Mitsubishi models, and understanding these differences can help you make the best choice for replacement or upgrade.

1. Mitsubishi Cylinder Head 1.5L 1468cc L4 4G15 - No Jet Valves

The Mitsubishi 1.5L 4G15 cylinder head is a popular choice for small, fuel-efficient Mitsubishi models. This cylinder head is designed without jet valves, which can simplify maintenance. Jet valves are typically used to help with emissions control, but in this case, Mitsubishi engineers opted for a design without them to maximize reliability and reduce potential wear points. Here’s what you can expect from the 4G15 head:

  • Ideal for compact models: The 1.5L 4G15 head is often found in smaller Mitsubishi vehicles, offering a balance of power and fuel efficiency.
  • Simplified design: Without jet valves, there’s less complexity, making this cylinder head easier to maintain.
  • Efficient combustion chamber: The 4G15 is known for efficient fuel burn, helping your Mitsubishi achieve decent performance without sacrificing fuel economy.

    • If you’re looking for a low-maintenance and reliable cylinder head, the 4G15 without jet valves is an intelligent choice for compatible Mitsubishi models.

    2. Mitsubishi Cylinder Head 1.6L 1597cc L4 4G61 - DOHC

    Moving up in power and complexity, the 1.6L 4G61 engine head is a double overhead camshaft (DOHC) design. This setup allows the engine to breathe better, providing more horsepower and torque than its single overhead cam (SOHC) counterparts. It’s a perfect fit for drivers who need a bit more performance from their Mitsubishi without going overboard.

  • DOHC Design: With dual cams, the 4G61 head offers improved valve timing and breathing, which translates to better power output and responsiveness.
  • Ideal for performance enthusiasts: If you love a bit of extra punch, the 4G61 DOHC head is an upgrade over simpler designs.
  • Smooth performance: The DOHC setup on the 4G61 helps your Mitsubishi’s engine perform smoothly even under load, providing a satisfying driving experience.

    • If you have a Mitsubishi model that’s compatible with the 4G61 DOHC head, this cylinder head can offer the extra edge in power and efficiency you may be looking for.

    3. Mitsubishi Cylinder Head 1.8L 1795cc L4 4G37

    The 1.8L 4G37 cylinder head is built for mid-range Mitsubishi engines prioritizing durability and balanced power output. Unlike the high-revving 4G61, the 4G37 is designed to offer a bit more torque, making it ideal for drivers who want a more robust performance without sacrificing efficiency.

  • Mid-range power: With a slightly larger displacement than the 1.6L, the 4G37 head delivers good mid-range power, ideal for city and highway driving.
  • Reliable and durable: Known for longevity, the 4G37 is a solid choice for daily drivers who value reliability.
  • Efficient for all-round performance: The 4G37 cylinder head is versatile, handling both city commutes and longer road trips with ease.

    • This cylinder head is an excellent option for those looking for a blend of performance and efficiency, suitable for a range of Mitsubishi models.

    4. Mitsubishi Cylinder Head 2.0L 1997cc L4 4G63

    The 2.0L 4G63 cylinder head is one of Mitsubishi’s most famous engine components, used in a variety of models, including some of the brand’s high-performance vehicles. This cylinder head offers ample power and performance, making it a popular choice for Mitsubishi fans who want the best in terms of engine output.

  • Powerful and versatile: The 4G63 cylinder head is designed to maximize performance, making it a favorite among enthusiasts.
  • High-performance compatibility: Often found in sportier models, the 4G63 is built to handle higher revs and provide robust power.
  • Upgradable potential: Many owners use the 4G63 as a base for performance modifications due to its durability and strong performance profile.

    • If you’re looking for a high-performance cylinder head that can be upgraded and customized, the 4G63 is a stellar choice.

    5. Mitsubishi Cylinder Head 2.0L 1997cc L4 G63B

    The G63B cylinder head is another 2.0L head, but it has a unique design that caters to specific Mitsubishi models. Similar to the 4G63, the G63B has been crafted with slight variations to fit different models, making it an essential option for those looking for an exact match.

  • Exact fit for specific models: The G63B is designed with specific model compatibility in mind, ensuring a precise fit for certain Mitsubishi engines.
  • Reliable power: Like the 4G63, the G63B offers solid power and performance, suitable for a range of driving conditions.
  • Balanced performance and efficiency: The G63B strikes a good balance, providing ample power without compromising too much on fuel efficiency.

    • For Mitsubishi owners looking for the right 2.0L cylinder head, the G63B is an ideal option for certain models, ensuring compatibility and reliability.
