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.

    Great toy for dogs or cats
    Color: Clemson Tigers, Size: Large, Color: Clemson Tigers, Size: Large
    Both my dog and cat love this treat finding toy. Dog (husky) can work it very quickly- the doors slide a bit too easily for him but the cat also successfully hunts up his treats as well. The quality seems nice and despite their use, still looks brand new.

    Product works great and looks nice. Stickers come up easily. Maybe not worth the price. But still is a good product.

    Quality
    Color: Missouri Tigers, Size: Large
    So i got this for my dog who was board and distroying the house and or having anxiety attacks. This was a cheap option and he loved it as a beginner puzzle. The covers slide so easily and don't stick like wooden puzzles. The amount of treat pockets is also great. The dog doesn't care what team it is related to and neither do I. If you are looking to keep your too smart dog entertained, tis is for you.

    My dog loves this toy
    Color: Iowa Hawkeyes, Size: Standard
    I've tried other engagement toys for my dogs but they didn't seem interesting to her. But my mini-Schnauzer loves this toy. She is excited when this toys comes out of the cabinet. It keeps her mind engaged. Easy to clean. Great value for the money.
