At Spectre, we pride ourselves on building the ultimate high performance air filters, and we call them hpR Filters – for HorsePower Rated. We tell everyone that our filters offer the ultimate in performance and protection, but unlike other companies on the market, we prove it – BIG TIME. How? By punishing our filters in the most brutal environment on the planet, the Bonneville Salt Flats.

Most streamliners run a single air intake scoop on top of the fuselage, where they can get nice clean air and they don’t have to run a filter at all. We run dual scoops on the bottom of the body close to the ground in a high-pressure zone, so we get a ram-air effect (which is good), but also vacuum up salt the entire length of the five mile course (which is bad). We typically pick up over 20 pounds of salt PER RUN, and most of it goes into the airbox. How do we prevent the turbos from ingesting big hunks of salt and grenading? With hpR filters.

What you see here is the first sneak preview of our new “Black” series ultra high performance hpR Filters. They look cool, flow an incredible amount of air and offer unmatched protection. As you can see, the outside of the filter is loaded with salt, but the inside is clean. As for power, our twin turbocharged Caddy powered SpeedLiner is (as of this writing) the fastest car of the meet at 349mph and has already set a record. We hope our good fortune will continue and we’ll continue to post big numbers for the rest of SpeedWeek. In the meantime, we thought everyone would get a kick out of knowing that we believe in our own product enough to punish it in with pounds and pounds of salt blown into the airbox at 350 mph.
