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.

    Not bad at all!
    These headlight cleaner wipes worked far better than I thought they would. I have used many a headlight cleaner and restorer, but this kit was the easiest to use with very good results. No need for power tools or even different sanding disks. Just two different types of wipes, super easy. We will see how long the lights stay clear for, but if I had to do it once a year it would be worth it! Four stars because the lights came out clear, but not crystal clear, but to be fair that may just be the condition of my headlights. Try this least expensive, easy fix first. It many very well be just what you need.

    Worth it for $12.
    Three stars for the progress it made on the lights of our 9 year old car. It works, but it won't look like new. Requires a bit of elbow grease, and it feels like a waste when the wipes run dry pretty fast. You have to keep them folded small (per the instructions) so they don't evaporate too fast, but then you get a tiny cleaning surface area as well. Spoiler alert: They still dry out fast. I wish I'd taken pictures for you because you WILL see a good improvement. Just don't expect brand new look. I'd say we had a maybe 75% improvement, and that combined with the new headlamps we installed made them work great. 4 stars if they want to come back and offer a like 2-4oz bottle of the chemical they use on the wipes and just let me use my own microfiber. That would be great.

    Product doesn't work as advertised
    This product does not provide enough wipes to remove more than the minimum amount of oxidation. The headlights were starting to yellow, so the oxidation was not severe. We followed the directions on the box to the letter and after using the wipes as directed were left with a sticky residue (which was left-over oxidation that the drying wipes could not remove). I am forced to purchase another box of the product in order to complete the job. I can't drive my car around with the tape protecting the body of the car on it, plus this is Florida so there would be bugs stuck in the tape and the sticky residue. A terrible product. Plus when I called them they said they would send me an email so I can tell them what the problem is and they would give it to their "research" staff to handle. I'm doing that and perhaps they will reimburse me for the second box I will have to get overnighted in order to finish the job.

    Armor All Car Headlight Cleaner Wipes – Quick & Easy Clarity
    The Armor All Car Headlight Cleaner Wipes are a convenient and effective solution for restoring foggy, yellowed, or hazy headlights without the need for complicated kits. These pre-moistened wipes make it super easy to wipe away oxidation and dirt, improving visibility and enhancing the car’s overall appearance. ✅ Pros: Quick & Easy to Use: No need for additional tools or sanding. Restores Clarity: Helps reduce haze and oxidation buildup. Convenient Packaging: Portable and easy to store in the car. No Harsh Chemicals or Strong Odors. ⚠️ Cons: May Require Multiple Uses for Heavily Oxidized Headlights. Not a Permanent Fix: Works best for maintenance but may not fully restore very cloudy headlights. Can Leave a Slight Residue: Needs buffing for the best shine. Final Verdict: For a quick fix and easy maintenance, the Armor All Headlight Cleaner Wipes are a great go-to option. They work well for light oxidation and keeping headlights clear, but for severely foggy lights, a full restoration kit may be needed. Great for touch-ups and convenience

    Foggy foggy to crystal clear in less than an hour!!! True story!
    Pleasantly surprised at a)how easy this kit was to use, b) the results of the kit and I highly recommend this kit. Took my headlights from completely foggy to crystal clear as if they were brand new. Only took about 30 minutes with a little elbow grease. Great product at a great price!
