Mitsubishi Evo X Firewall Heat Shield by MAPerformance

Firstly, Buy MAPerformance Evo X Firewall Heat Shield EVOX-FHS-REV2 for 2008–2015 models. Protect the rear of your Mitsubishi Lancer Evolution X engine bay from excessive turbo and exhaust-manifold heat with the Mitsubishi Evo X Firewall Heat Shield by MAPerformance. Designed specifically for the Evo X platform, this heat shield creates a protective barrier between the high temperatures generated by the turbo and exhaust manifold and important components mounted around the firewall.

The MAPerformance EVOX-FHS-REV2 is constructed from brushed 16-gauge 304 stainless steel and uses a two-piece design for easier installation. The large coverage area helps shield the firewall, ABS unit, brake lines, and surrounding components from radiant heat. MAPerformance also designed the shield to work with tubular and cast manifolds, including many aftermarket exhaust manifold configurations.

MAPerformance Evo X Firewall Heat Shield

The engine bay of a turbocharged Evo X can generate significant heat, especially around the turbocharger and exhaust manifold. This becomes even more important on modified cars running upgraded turbos, tubular manifolds, or other performance exhaust components.

The MAPerformance Evo X Firewall Heat Shield is designed to address this problem by placing a durable stainless-steel barrier between the heat-producing components and the firewall area.

This is more than an appearance upgrade. It is a practical thermal-management component designed to help protect surrounding hardware from the intense heat produced at the rear of the 4B11T engine.

MAPerformance specifically developed this version as a two-piece design. This makes installation easier than the company’s earlier one-piece design and allows the shield to be installed around the factory and aftermarket drivetrain components with less difficulty.

16-Gauge 304 Stainless Steel Construction

The firewall heat shield is manufactured from 16-gauge 304 stainless steel with a brushed finish.

304 stainless steel provides the durability needed for an engine-bay environment exposed to high temperatures, vibration, and normal road conditions. The material also gives the heat shield a clean, performance-oriented appearance.

The large shield design provides broad coverage across the firewall rather than concentrating protection around only one small component.

This makes it particularly useful for modified Evo X engine bays where exhaust and turbo components may produce considerably more heat than the original setup.

Protects the ABS Unit and Brake Lines

One of the most important functions of this heat shield is protecting components located close to the turbo and exhaust manifold.

MAPerformance specifically designed the shield to help protect the ABS unit and brake lines from heat generated by the manifold, turbocharger, and other exhaust components.

Excessive heat in this area can also affect surrounding insulation and nearby components. On performance builds, controlling radiant heat around the rear of the engine can therefore be an important part of overall engine-bay protection.

By creating a physical barrier, the MAPerformance firewall heat shield helps reduce direct exposure to radiant exhaust heat.

Designed for Modified Evo X Builds

The MAPerformance firewall heat shield is not limited to completely stock Evo X configurations.

The shield is designed to work with tubular and cast exhaust manifolds, as well as nearly all aftermarket exhaust manifolds according to MAPerformance.

That makes it a useful upgrade for Evo X owners running:

• Aftermarket turbochargers
• Tubular exhaust manifolds
• Cast performance manifolds
• Upgraded exhaust systems
• High-power 4B11T builds
• Track-focused engine setups
• Modified street Evo Xs

Before installation, always check clearance around your specific turbo and manifold combination.

Two-Piece Design for Easier Installation

One of the biggest improvements of the REV2 design is its two-piece construction.

The two stainless-steel panels can be assembled using the included hardware and then installed in the engine bay. Depending on the manifold and turbo configuration, MAPerformance states that installation can generally be completed without removing the turbo or exhaust components.

The installation guide shows the two pieces being joined before installation, although some manifold configurations may require the shield to be assembled inside the engine bay to provide sufficient clearance.

This approach makes the shield much more practical for owners who want improved heat protection without undertaking a major engine-bay teardown.

Easy Installation with Included Hardware

The kit includes the hardware required to install the shield.

The package contains:

• 2 × MAP stainless-steel heat shields
• 4 × M6 clip nuts
• 4 × M6 10 mm-head stainless flange bolts
• 2 × M8 stainless flange locking nuts
• 2 × M6 8 mm-head washer bolts

The installation requires basic hand tools. MAP’s installation guide lists a 10 mm socket, 14 mm socket, and 3/8-inch ratchet as the primary tools.

2008–2015 Mitsubishi Evo X Fitment

The MAPerformance Evo X Firewall Heat Shield is designed for the 2008–2015 Mitsubishi Lancer Evolution X.

MAPerformance also lists the shield for the 2008–2015 Mitsubishi Lancer Ralliart.

For Evo X applications, the product is suitable for the CZ4A platform across the listed model years.

Because aftermarket turbo and manifold configurations can vary considerably, check the clearance of your specific setup before installation.

Why Upgrade the Evo X Firewall Heat Shield?

The factory engine bay was designed around the original turbocharger and exhaust configuration. Once you install a larger turbo, aftermarket manifold, or other performance components, the thermal environment can change.

A dedicated firewall heat shield provides an additional layer of protection.

Firstly, it helps protect the ABS unit and brake lines from direct radiant heat.

Secondly, its large coverage area protects more of the firewall and surrounding engine-bay components.

Thirdly, the stainless-steel construction provides a durable solution that can withstand the demanding conditions of a turbocharged performance engine bay.

For Evo X owners building a reliable street, track, or high-power car, thermal management should be considered alongside engine and drivetrain upgrades.

What is the heat shield made from?

It is made from 16-gauge 304 stainless steel with a brushed finish.

What does the shield protect?

It is designed to protect the firewall area, ABS unit, brake lines, and nearby components from heat produced by the turbocharger, exhaust manifold, and other exhaust components.

Does it fit aftermarket manifolds?

Yes. MAPerformance states that the shield fits tubular and cast manifolds and nearly all aftermarket exhaust manifolds. Clearance should still be checked on heavily modified setups.

Does the turbo need to be removed for installation?

The two-piece design was specifically developed to make installation easier without removing turbo or exhaust components in most configurations. Exact installation may depend on the manifold and turbo setup.

What years does it fit?

The listed Evo X application is 2008–2015 Mitsubishi Lancer Evolution X. It is also listed for 2008–2015 Mitsubishi Lancer Ralliart.

Is installation hardware included?

Yes. The kit includes the two heat-shield panels, M6 clip nuts, stainless flange bolts, M8 locking nuts, and M6 washer bolts.

Is this the same as an exhaust manifold heat shield?

No. This is a firewall heat shield. It is positioned to protect the firewall and nearby components from heat produced by the turbo and exhaust manifold, while a conventional manifold heat shield is designed primarily around the exhaust manifold itself.

Does it come with a warranty?

MAPerformance lists a Limited Lifetime Warranty for this product.
