Hey Paul, We had a technical issue earlier, but the sale is now active on the site. Sorry for the inconvenience!
Hey Robert, K&N is not discounted on site. They are running a mail-in rebate. See our K&N and Airaid-Specific blog post: https://www.stage3motorsports.com/K&N-and-Airaid-50-Rebate-On-Cold-Air-Intakes-over-250-2019.html
I bought a 2011-2016 Mustang / F150 3.7L AIRAID Throttle Body Spacer Kit thinking because it’s listed to have a $50 rebate. I can only find the rebate for the cold air intakes. How do I receive the rebate that is listed in the product description?
