But how do you install a heat shield in your Subaru BRZ? This article will provide a comprehensive guide to assist you in performing this task. We will explore a top-quality product, the Grimmspeed heat shield kit, the importance of a heat shield, the steps to install it, and how to save on costs.

What is a Heat Shield and Why Do You Need One?

A heat shield, also known as a turbo blanket, is a protective device that shields the turbocharger and other engine components from extreme heat. Turbochargers, due to their nature of operation, produce a lot of heat. This heat can cause damage to components that are sensitive to high temperatures, affect the performance of the vehicle, and even lead to premature engine wear.

The heat shield is typically made from high-quality stainless steel. This material is known for its excellent heat resistance properties, and it also offers a protective barrier that can prolong the lifespan of your vehicle’s turbocharger.

One noteworthy product in this category is the Grimmspeed heat shield kit. This kit is specifically designed for Subaru vehicles and is touted to offer superior heat protection compared to the stock heat shield provided by Subaru.

Comparing Grimmspeed Heat Shield Kit to the Stock Subaru Heat Shield

The original heat shield provided by Subaru in its stock condition is made to handle the standard heat conditions of the vehicle’s engine. However, for those of you who drive your Subaru BRZ under high-performance conditions, the stock heat shield may not provide sufficient protection, making the Grimmspeed heat shield kit a worthy upgrade.

The Grimmspeed heat shield is constructed from high-quality stainless steel and features a black thermal discoloration resistant coating. This coating not only gives the product an aesthetically pleasing finish but also provides additional heat resistance, making it superior to the stock heat shield.

Moreover, the Grimmspeed product includes provisions for the oil supply lines, making it easier and more convenient to install than the stock heat shield.

Steps to Install the Grimmspeed Heat Shield Kit

Installing a heat shield on your Subaru BRZ is a straightforward task that you can accomplish with some basic automotive knowledge and a few tools. Let’s break down the steps:

  1. Lift the vehicle and secure it on jack stands.
  2. Remove the stock heat shield. This is typically held in place by bolts. Use a socket wrench to remove them.
  3. Once you have removed the stock heat shield, clean the area around the turbocharger.
  4. Position the Grimmspeed heat shield over the turbocharger and secure it in place using the provided bolts. Ensure that it fits snugly over the turbocharger, without obstructing any other engine components.
  5. Lower the vehicle from the jack stands.

Note: Always refer to the product’s installation guide provided by the manufacturer for specific instructions related to your vehicle model.

How to Save on Heat Shield Installation Costs

While the price of a Grimmspeed heat shield kit might seem steep to some vehicle owners, it’s an investment worth making considering the potential cost of damages due to heat exposure. The good news is, there are ways to save on heat shield installation costs:

  1. Do it Yourself: As mentioned earlier, installing the Grimmspeed heat shield kit is straightforward. By doing it yourself, you save on the labor costs that you would otherwise pay a mechanic.
  2. Shop Around: Different retailers offer varying prices for the same product. Take the time to compare prices from different sellers before making a purchase.
  3. Buy Used: If a new heat shield is out of your budget, consider purchasing a used one. However, ensure that it’s in good condition before buying.

While heat is an inevitable by-product of your Subaru BRZ’s turbocharger, it doesn’t have to be a cause for concern. A heat shield, particularly the Grimmspeed kit, can provide the necessary protection your turbo needs. By following the steps outlined in this guide, you can install a heat shield yourself and save on costs. Remember, a well-protected turbo is crucial in maintaining your vehicle’s performance and prolonging its lifespan.

The Importance of the Heat Shield’s Material and Design

When it comes to turbo protection, the material and design of the heat shield play a crucial role in its efficiency. As we mentioned earlier, heat shields are typically made of stainless steel, a material known for its excellent heat resistance properties. Some high-quality shields, like the Grimmspeed Turbo Shield kit, feature a special black thermal discoloration resistant coating, which not only provides additional heat resistance but also gives the shield an aesthetically pleasing finish.

Heat shields come in varying designs, with some providing better coverage than others. The Grimmspeed shield, for instance, includes provisions for the oil supply lines, making it easier to install and offering superior protection of the turbocharger and surrounding engine components. Furthermore, the shield fits snugly over the turbo without obstructing any other engine components, ensuring optimal protection.

An important factor to consider is the heat shield’s ability to reflect gold. Gold foil is often used in heat shields due to its high heat-reflective properties. The Grimmspeed shield, however, doesn’t incorporate reflective gold into its design but relies on high-quality stainless steel and a black thermal discoloration resistant coating for heat resistance, proving that gold foil isn’t a necessity for effective heat shielding.

Is a Heat Shield Necessary for Your Subaru BRZ?

The answer is a resounding yes. A heat shield is indeed a crucial component for your Subaru BRZ, especially if you often drive under high-performance conditions. Excessive heat produced by the turbocharger can cause premature engine wear, hindering your vehicle’s performance and potentially leading to costly repairs.

Installing a heat shield is a preventative measure, protecting your turbocharger and other engine components from extreme heat. It is also a cost-effective solution, as the price of a heat shield, be it high or low, is significantly less than the cost of repairing or replacing damaged engine components.

California Cancer and Reproductive Harm warnings have also been associated with products lacking adequate heat protection. In other words, investing in a high-quality heat shield like the Grimmspeed turbo kit can help protect you and your vehicle’s occupants from potential health hazards.


In conclusion, a heat shield is a necessary component for any turbocharged vehicle, including the Subaru BRZ. It not only prevents damage from excessive turbo heat but also maintains engine performance and extends the lifespan of the engine. The Grimmspeed Heat Shield Kit, with its high-quality stainless steel construction and thoughtful design, offers superior protection compared to the stock Subaru heat shield.

While the initial cost might seem steep, it’s a worthwhile investment considering the potential savings from future repairs and improved engine performance. You can also save on installation costs by doing it yourself, following the straightforward steps outlined in this guide. Ultimately, protecting your engine with a heat shield contributes to a smoother and safer driving experience. Remember, a well-protected turbo is crucial for the longevity and performance of your Subaru BRZ.
