Davis Bellew Subaru has built a strong reputation for building reliable and high-performance vehicles. It’s no wonder that many car enthusiasts and Subaru owners invest in aftermarket upgrades, such as installing a blow off valve, to improve their car’s performance. One of the most common questions that car owners tend to ask is whether installing a blow off valve would void their Subaru’s warranty. In this article, we will explore the impact of adding a blow off valve to your Subaru and whether or not it can void your car’s warranty.
Understanding Blow Off Valves
Before diving into the impact of adding a blow off valve to your Subaru, let’s first understand what it is and how it works.
A blow off valve (BOV) or a diverter valve is a device used in a turbocharged or supercharged engine. It is designed to relieve the pressure that builds up in the intake system when the throttle is closed, such as during a gear change. A BOV works by releasing the compressed air that is trapped in the turbocharger’s compressor housing, causing a signature sound that many car enthusiasts love.
Will a Blow Off Valve Void Your Subaru’s Warranty?
The answer to whether a blow off valve will void your Subaru’s warranty is not a straightforward one. It depends on the car dealership or manufacturer’s policies. Typically, dealerships and manufacturers will void the warranty if they can prove that the aftermarket modification caused the problem or damage experienced by the car.
Subaru’s warranty policy states that any modification that affects the powertrain is not covered by the warranty. A BOV is considered an emissions-related component of the engine, and any failures or issues caused by the BOV installation may void your car’s warranty.
However, some Subaru dealerships and manufacturers may be more lenient and allow certain aftermarket modifications. It’s essential to check with your dealership or manufacturer before making any modifications to your car.
The Legality of Installing a Blow Off Valve
The installation of a blow off valve is legal in the United States and many other countries. However, some states have specific rules and regulations regarding the installation of aftermarket parts. It’s important to research the laws in your state before installing any aftermarket upgrades.
Alternative Ways to Improve Subaru Performance Without Voiding the Warranty
If you’re looking to improve your Subaru’s performance without voiding the warranty, there are alternative modifications you can consider. Here are some options:
- Performance Air Filter: A high-performance air filter can increase airflow and improve the car’s performance. It’s an easy and affordable modification that won’t void your car’s warranty.
- Cat-Back Exhaust: Upgrading your car’s exhaust system can improve airflow and increase horsepower. A cat-back exhaust system replaces the factory exhaust system from the catalytic converter back, reducing restriction and increasing horsepower.
-
Tuning: A professional tune can optimize your car’s engine and increase performance without sacrificing reliability. A proper tune can significantly improve horsepower, torque, and even fuel economy.
It’s important to note that any engine modification may have an impact on your car’s warranty. Be sure to check with your dealership or manufacturer before making any changes.
Maintaining Your Subaru’s Warranty While Making Aftermarket Modifications
If you plan on making any aftermarket modifications to your Subaru, it’s essential to take steps to maintain your car’s warranty. Here are some tips:
- Keep Records: Keep a record of all the upgrades and installations you’ve made to your car. This information may be helpful in the event of a warranty claim.
- Install OEM Parts: When possible, install original equipment manufacturer (OEM) parts and accessories. This will ensure that the aftermarket parts installed on your car meet the manufacturer’s specifications.
- Find a Reputable Installer: Choose a reputable installer when making aftermarket modifications to your car. A professional installer will ensure that the installation is done correctly and safely.
- Check with Your Dealership or Manufacturer: Before making any modifications to your car, check with your dealership or manufacturer to ensure that it won’t void your warranty.
