Why Upgrade to MAPerformance Coolant Hose Kits?

Your engine’s cooling system is just as critical as its power output—after all, high performance means nothing if your engine overheats, and if that happens, you can pretty much say goodbye to all those power upgrades you were looking forward to. Stock rubber coolant hoses degrade over time, leading to leaks, pressure loss, and inefficiency, and that's not even mentioning the massive amounts of potential damage your engine could suffer if leaks do happen. 

Because of this, we recommend upgrading to silicone radiator hose kits from MAPerformance - they offer durability, improved cooling efficiency, and long-term reliability for high-performance cars from every make and platform. In this guide, we’ll cover the benefits of aftermarket coolant hoses and highlight four of our favorite MAPerformance silicone radiator hose kits designed for top performance.

Benefits of Aftermarket Silicone Coolant Hoses

First off, if you're on the fence about upgrading such a seemingly minor part, the obvious question is "what makes silicone coolant hoses worth the investment?" There are a few key advantages that our coolant hoses bring to the table over stock options, including: 

1. Superior Heat and Pressure Resistance

Stock hoses degrade under extreme heat and pressure, leading to swelling, cracking, and leaks over time. Silicone hoses handle higher temperatures and pressures, making them ideal for tuned or track-driven cars.

Example: Turbocharged engines like the 10th Gen Civic 1.5T benefit significantly from silicone hoses, preventing heat-related failures.

2. Longer Lifespan and Durability

OEM rubber hoses are prone to drying out, cracking, and hardening over time. Silicone construction resists aging, corrosion, and UV exposure, making it a long-term upgrade for reliability.

Example: The 11th Gen Honda Civic Si Silicone Radiator Hose Kit provides a lifetime solution to coolant hose issues.

3. Enhanced Aesthetics 

Silicone hoses look cleaner and more aggressive under the hood, enhancing the overall engine bay aesthetic. These kits offer a custom look while maintaining high performance.

Of course, your hood will need to be open for this to fully hit, but imagine rolling up to the show, popping the hood and flexing that your engine looks better than some peoples' entire builds. Unbeatable. 

Example: The BRZ/GR86 Silicone Radiator Hose Kit gives your FA24-powered coupe an aesthetic and functional upgrade.
