Complementing the new Apex Phantom, Aeromotive also releases its proprietary new Phantom Bladder Baffle, which literally opens and closes the door on Phantom flow control technology. While providing a continuous, high fuel flow into the Phantom Baffle using the Apex Phantom is awesome, it?s critical to allow a large volume of fuel to flow into the baffle naturally from the surrounding tank. It is also important to keep it there. The Phantom Bladder Baffle can ensure this. Installed in the inlet passages at the base of the Phantom Bladder, the new Phantom Bladder Baffle increases the flow area into the Bladder to promote rapid fuel recovery from the surrounding tank while deploying a PTFE check ball that acts to keep that critical fuel in the bladder, preventing it from escaping during hard acceleration, cornering, and off-angle vehicle maneuvers. Aeromotive?s Phantom Bladder Baffle is constructed with CNC-machined billet aluminum valve bodies, which are then anodized and loaded with a PTFE check ball and locked in to the Phantom bladder with a PTFE retaining washer. The Phantom Bladder Baffle is designed for durability and is fully compatible with gasoline and ethanol fuels. It requires no special tools and may be used in any existing or new Phantom bladder, with the Apex Phantom, or as a stand-alone solution to slosh control. Aeromotive?s Phantom Bladder Baffle is available in sets of 4 (P/N 18020) for the standard Phantom Bladder used in the Phantom 200 and Phantom 340 pump kits, or in sets of 5 (P/N 18021) for the larger Phantom Bladder used in the Phantom Flex and Phantom Dual.

Why Drivers Choose FAST of West Chester

  • I can't recommend this place enough. Being able to trust a shop in the performance world is big. The 2hr drive to get there, is worth knowing the job will be done right. Very happy to have found this shop, to
    support my builds going forward.


    Donald Wojnar
  • I recently had the pleasure of working with FAST of West Chester for some performance upgrades on my 2022 WRX, and the experience was nothing short of exceptional. I opted for a Borla S-Type exhaust and Cygnus Coilovers, and the team at FAST nailed the installation, fitment, and setup to a T.


    Adam Cranston
  • The team at FAST are excellence in every way. First, I consulted with Dave on mods for my HPDE track car. He listened and advised me on the best parts & mods to achieve my goals. He was patient & gave me space to research the options presented & worked with me through several changes before we built. Second, the build execution was flawless, proper heat shielding, bracing and poly everywhere. All components worked as advertised.


    Bryce Budd
  • This place has been my go to shop for all things Subaru. From simple service to performance parts and tuning, they have been top notch.


    William Brunell
  • Excellent shop. They installed a Cobb Stage 2 DP and Whiteline Sway bars and end links on my 2013 WRX. The work was done right and clean. The estimate was accurate. They were very knowledgeable, friendly and gave me the straight scoop on exactly what I was getting for the money
    and what I needed to get where I want to be with it. I'd recommend them
    to any car enthusiast.
