Upgrade Guarantee

Once a customer, always a customer

We don't forget about you after your initial purchase. If we release a new intake kit for your vehicle, you can upgrade for as low as $179.

How To Upgrade:

1. Verify your kit has been upgraded below.
2. Create an online S&B account.
3. Login to your account and purchase the new intake kit at full price.
4. Once you have received and installed your new intake kit, email [email protected] requesting an Upgrade Credit. Be sure to include the name, phone number and email you purchased the new intake under. You will receive a Return Authorization Code within 1 business day.
5. Send back the old intake tube with your Return Authorization Code on the box and ship it to the address below. You only need to send the tube and not the entire kit.
   • S&B Filters
   • Product Upgrades
   • 15461 Slover Avenue
   • Fontana, California 92337
6. We will process the credit immediately upon receipt of the old intake tube. Please allow one billing cycle for the refund to show up on your actual credit card statement. While we realize that this process is a bit more difficult than we would prefer, it is necessary in order to deter exploitation of this valuable upgrade offer.
