BBK fuel pressure regulators are direct replacements for your stock pre-set regulator and offer the best performance and value. Tuning is accomplished with the simple twist of a screw.

BBK Performance starts every year by creating a “wish list” of ideas for the year. They evaluate each idea in light of the company’s three main values: every BBK product must offer real-world performance gains, OEM quality and durability, and affordability for the DIY enthusiast. If a product doesn’t meet those criteria, then it’s sent back to the drawing board. They test every component for fit and then dyno-test vehicles to measure the actual performance numbers. Zip is a proud dealer of BBK products. Contact us to learn what’s new from BBK.
