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 supercharger systems ship within 3-5 business days. Custom finishes or build-to-order kits may require an additional 2-4 weeks for calibration and assembly.
Do Magnuson superchargers come with a warranty?
Yes, all our superchargers include a standard 3-year/36,000-mile limited warranty. We also offer an optional powertrain warranty for added peace of mind on qualifying vehicles.
Will installing a supercharger void my vehicle's factory warranty?
Under the Magnuson-Moss Warranty Act, a dealer cannot void your entire warranty simply because an aftermarket part is installed. However, we recommend checking with your local dealer and considering our supplemental powertrain warranty.
What is your return policy for performance parts?
Unopened and unused items can be returned within 30 days of delivery, subject to a 15% restocking fee. Please note that installed components or custom-tuned kits are not eligible for return.
Do you offer international shipping?
Yes, we ship our performance products worldwide. International customers are responsible for all applicable duties, taxes, and brokerage fees required by their local customs office.
What kind of fuel is required after installation?
To ensure engine safety and maximum performance, all Magnuson supercharged vehicles require the use of premium unleaded fuel (91 octane or higher).
