Can Upgrading to Silicone Radiator Hoses Benefit Your Subaru Impreza?

April 4, 2024

When it comes to auto maintenance, every detail matters – from the largest parts to the smallest bolts. Indeed, ensuring your vehicle operates at its optimal performance requires a great deal of attention to detail. For Subaru Impreza owners, one such detail is the radiator hose. This small but essential component plays a critical role in your vehicle’s cooling system. The question that arises then is: can upgrading to silicone radiator hoses benefit your Subaru Impreza? This article will provide you with valuable information regarding the advantages of this upgrade, the options available, and how to find the right product for your vehicle.

The Significance of the Radiator Hose

Firstly, let’s understand the role a radiator hose plays in your vehicle’s functioning. The radiator hose carries the coolant – a mixture of water and antifreeze – to and from the engine. It ensures that the engine operates within its optimal temperature range by preventing it from overheating.

Typically, radiator hoses are made of rubber. However, rubber is subject to wear and tear, which can cause it to crack and leak over time. This is where silicone hoses come in. Silicone is a more durable material and can withstand higher temperatures than rubber, making it a preferred choice for many vehicle owners.

Benefits of Upgrading to Silicone Radiator Hoses

Switching to silicone radiator hoses carries several benefits. For starters, silicone raditor hoses are more durable and longer-lasting than their rubber counterparts. They can withstand higher temperatures and pressures, significantly reducing the risk of leaks and breakdowns.

In addition to durability, silicone hoses also enhance the performance of your vehicle. They have a smoother inner surface which allows for a more efficient coolant flow, thus improving the cooling efficiency of your engine.

Lastly, silicone radiator hoses add an aesthetic appeal to your vehicle. They are available in various colors such as blue, making your engine bay look cleaner and more customized.

When it comes to selecting a silicone radiator hose for your Subaru Impreza, one of the leading brands that come to mind is Mishimoto. The Mishimoto silicone radiator hose kit is specifically designed to fit Subaru Impreza WRX models.

Finding the Right Product at the Right Price

With a multitude of auto parts suppliers online, finding the right product at the right price can be a daunting task. However, auto forums can be a valuable resource in your search.

Forums like the Subaru Impreza forum have dedicated sections where members share their experiences with different products and suppliers. You can take advantage of this information to find a high-quality, competitively priced silicone radiator hose for your Subaru Impreza.

In addition, most of these forums have marketplaces where members sell their used parts. This could be an excellent opportunity to find a good quality silicone radiator hose at a reduced price.

Final Thoughts on Shipping and Installation

Once you have found the right product at the right price, the next step is to add it to your cart and checkout. Many suppliers offer free shipping on orders above a certain amount, so be sure to check the shipping policy before finalizing your purchase.

As for installation, while it’s possible to do it yourself, it’s recommended to have a professional handle it to ensure it’s done correctly and safely.

In conclusion, upgrading to a silicone radiator hose can indeed benefit your Subaru Impreza in terms of durability, performance, and aesthetics. It may seem like a small change, but it can make a big difference.

Longevity and Efficiency of Silicone Radiator Hoses

Silicone radiator hoses offer a significant advantage in terms of durability. Unlike rubber hoses, which tend to crack and leak over time due to wear and tear, silicone hoses are renowned for their ability to withstand higher temperatures and pressure. Consequently, this decreases the risk of leaks and potential damage to your Impreza. Furthermore, silicone hoses are resistant to a spectrum of environmental factors such as UV radiation, ozone, and harsh weather conditions, which typically degrade rubber over time.

Silicone hoses also operate more efficiently due to their smoother inner surface. By facilitating a more dynamic flow of coolant, the engine’s cooling efficiency is enhanced. In simpler terms, your Subaru WRX will be less likely to overheat, ensuring consistent performance and longevity of your engine.

In terms of aesthetics, a silicone radiator hose can make your engine bay visually appealing. With various color options available, you can customize your Impreza radiator hose to match your personal style or the overall look of your vehicle.

Making the Switch: Installing Your New Silicone Radiator Hose

After purchasing your hose kit, the next step is to get it installed in your Subaru Impreza. While the process is achievable for a DIY enthusiast, it’s highly recommended to have a professional carry out the installation. This ensures that the hose is correctly fitted, decreasing the chance of leaks or other complications down the line. If you do choose to go the DIY route, ensure you have the correct tools and safety equipment on hand.

The Mishimoto Subaru radiator hose kit includes both the upper and lower radiator hoses and the necessary worm gear clamps for installation. The MMHose WRX kit also comes with a comprehensive set of instructions, which should be followed meticulously to ensure a successful installation.

It’s essential to note that after installing a new silicone radiator hose, it’s recommended to check it regularly for the first few weeks. This helps confirm that the installation was successful and the hose is functioning as expected.


In sum, upgrading to a silicone radiator hose can certainly benefit your Subaru Impreza. While the initial cost may be higher than a standard rubber hose, the long-term benefits including increased durability, improved cooling efficiency, aesthetic appeal, and ultimately, enhanced performance of your vehicle, make it a worthy investment.

Remember, an upgrade to a silicone hose isn’t just about improving the look of your engine bay. It’s about ensuring the longevity and performance of your Subaru WRX. So take the plunge, add that hose kit to your cart, and give your Subaru Impreza radiator the upgrade it deserves. Be it the Mishimoto Subaru or any other trusted brand, make sure you quick view the specs, check the image URL for details, and consider the original price against the minimum formatted price to ensure you’re getting the best product at the best price.
