Overview:

Serious drag racing demand a serious drag racing carburetor, and the QFX-Series stands as the flagship model in QFT's lineup. Raised air horns improve entry angle into the venturi while ensuring undisrupted flow over the air bleeds. Annular boosters with CNC-machined billet aluminum inserts provide increased air flow, a stronger signal, and less turbulence. QFX carbs offer unparalleled fuel atomization with annular boosters specific for either gas, methanol, or E85 fuels. Five-emulsion billet metering blocks and four-corner idle circuits offer flexible tunability that today's high-horsepower engines demand. To cover a broad range of applications, methanol- and E85-compatible models, as well as two- and three-circuit fuel systems, are available. Ready to run out of the box, the QFX-Series carburetor will help you get to the winner's circle.
Even a carburetor that performs great can still be an eyesore, but it doesn't have to be that way. Quick Fuel Technology's proprietary Black Diamond® coating offers excellent corrosion resistance as well as a durable finish that easily stands up to dirt and oil. In addition to great looks, the PTFE coating reduces fuel temperature by six percent for improved performance.

    Tough enough.
    These seem to be more durable than the other toys I bought from this same supplier. The dogs like them and they are fairly tough. They are still in good shape after a couple of weeks of play with my dogs. I would probably get these again.

    My doxins loved these toys. I loved them more that there was no stuffing mess to clean up! Good squeaker noise. Soft for their gums

    Worth it if your dog destroys plush toys & likes to chew
    Color: Cyan NylonFish
    My dog is a very big chewer and destroyer of toys. This toy is perfect for her. It is durable and keeps her engaged chewing for a while. I have a 55lb dog, considered a large dog, and it’s a great size for her. She’s unable to break it apart. The ends do tend to get a little sharp after extended use

    My Boston loves this fish toy
    Color: Cyan NylonFish
    Very durable. It takes a couple of months of intense chewing to make holes in this toy. My Boston has incredible mouth strength so he destroys most toys in minutes unless they are rocks. I have replaced this fish 2 times in the last year. I keep an eye on the wear and replace it when he makes a hole in it. Worthwhile purchase but monitor the dogs chewing.

    Great sturdy toy
    Color: Cyan NylonFish
    Great toy. 1 yr old puppy LOVES it! However, not good for TILE FLOORS. It's so strong and sturdy but bangs all over the tile! Enough to crack tiles 😬
