Frequently Asked Questions
Everything you need to know about boosting your vehicle's performance.
How long does shipping take for a supercharger system?
Most in-stock systems ship within 3-5 business days. Custom finishes or out-of-stock items may require a lead time of 2-4 weeks. You will receive a tracking number as soon as your order leaves our warehouse.
Do Magnuson Superchargers come with a warranty?
Yes, all our supercharger systems include a standard 3-year/36,000-mile limited warranty. We also offer an optional powertrain warranty for added peace of mind on newer vehicles.
What is your return policy for performance parts?
Unopened and uninstalled kits can be returned within 30 days of purchase, subject to a 15% restocking fee. Please note that custom-built or installed components are not eligible for return.
Will installing a supercharger void my factory vehicle warranty?
Under the Magnuson-Moss Warranty Act, a dealer cannot void your entire warranty simply because an aftermarket part is installed. However, they can deny coverage if it is proven that the aftermarket part caused a specific failure.
Do you provide ECU tuning with your kits?
Most of our complete systems include a handheld programmer and a calibrated tune specifically designed for your vehicle. Tuner kits (labeled as 'Tuner Kits') do not include a calibration or fuel components.
What type of fuel is required after installation?
To ensure engine safety and optimal performance, all Magnuson supercharged vehicles require the use of premium unleaded gasoline (91 octane or higher).
