Audi S4 Engine & Cabin Filter Replacement

The B9 Audi S4 is an easy car to service when it comes to the engine filter. It shouldn't take more than a few minutes to swap yours with hand tools. The carbon air filter on the other hand was a bit of a pain just due to the cramped conditions. Overall give yourself at least 20 minutes for a first time swap of both filters. Once you are familiar with the process you'll be doing both in minutes.

Your wax isn't blocking UV!

Does wax block UV? Today we re-visit my UV testing methods and see if a new approach to testing tells us more about how waxes block UV light. In our new test I pit Chemical Guys Jet Seal against our new testing gear. I utilize a BPI Perfect Vision UV/Photometer III and a Linshang LS162 Transmission Meter to see how much protection our tested wax provides. I then tested all the products from my prior videos. The uv blocking results may shock you!
