Vixen Horns VXO8330/1164 Single-Trumpet Horn Kit Review (2026)

Methodology

This review aggregates publicly available information from manufacturer specifications, retailer listings, and verified user reviews. We do not perform hands-on testing. Last reviewed: 11/01/2026. For this article we used Vixen Horns’ official product page for this exact SKU, the matching six-page VXO8330/1164 installation guide (hosted by authorized dealer HookedOnTronics), Vixen’s pages for the horn-only VXH1164 and the standalone VXO8330 air system, the black and 5-gallon variants of this kit, Vixen’s published warranty policy, and the Amazon listing for the same model number. Every number in the spec table comes from a source listed at the bottom of the page. Anything that reads as a judgment call is our editorial opinion.

Quick verdict

The VXO8330/1164 pairs one long chrome semi-truck trumpet with a big air system: a 3-gallon tank and a 200 PSI compressor that Vixen rates at a 100% duty cycle at 100 PSI. On paper that is far more air than one trumpet needs, so the horn should keep sounding long after smaller kits run dry. The trade-offs are a single-note sound instead of a train-horn chord, no published decibel rating at any distance, and a price of about $271 that sits close to Vixen’s own multi-trumpet kits. We rate it 3.6/5: a well-documented kit that makes sense if you want a classic semi-truck blast with plenty of reserve air, but not if you want a true train-horn chord.

What it is

The VXO8330/1164 is a complete onboard air horn kit. Vixen combines two products it also sells separately: the VXH1164 “Semi Truck Single Air Horn” in chrome-plated metal, and the VXO8330 onboard air system (3-gallon tank plus 200 PSI compressor). Vixen describes it as “a full train horn system, ready to install” for “all vehicles with a 12V system.”

One point buyers often miss is the trumpet count. Most train horns get their sound from several trumpets tuned to a chord. This kit has one 25-inch trumpet, so it plays a single deep note, closer to a big-rig air horn than a locomotive. Vixen’s own name for the horn-only version is “Semi Truck Single Air Horn,” and its product page hosts an MP3 sound clip of the VXH1164 so you can hear the tone before buying. If you are unsure which format you want, our guide on single vs. dual vs. quad trumpets explains the difference.

The kit suits pickup, SUV and semi owners who want a loud single-note horn and value air reserve and compressor stamina over a multi-note chord. The same kit also comes with a black horn and compressor as the VXO8330B/1164B, and with a 5-gallon tank as the VXO8350/1164. Both are covered in the alternatives below. All of Vixen’s kits are listed on our Vixen Horns brand hub.

What’s in the box

According to Vixen’s product page and the installation guide’s contents list, the kit includes:

• Single trumpet air horn, chrome plated, with mounting bolts, nuts, washers and gaskets
• 12V/24V electric air valve (solenoid) with compression fitting
• 200 PSI air compressor with ¼” NPT stainless steel braided leader hose and inline check valve
• Intake filter assembly (the guide calls it a remote-mount air filter)
• 30A in-line fuse with waterproof holder and insulated wiring with connectors
• 3-gallon air tank with mounting hardware
• 240 PSI air pressure gauge
• 170–200 PSI pressure switch
• 250 PSI safety valve
• ¼” NPT wing-style drain valve
• ¼” NPT compression fitting for 3/8” OD air line, plus ¼” and ½” NPT hex-head plugs
• 3/8” OD nylon air line (10 ft)
• 12 mm thread sealant tape (16 ft)
• Horn button

Not included: the 10A fuse the guide specifies for the solenoid circuit, and the 12-gauge or heavier power wire it requires for the compressor.

Pros

• Much more air than one trumpet needs. A 3-gallon tank feeding a single horn should give long blasts and quick repeat honks (editorial inference from the specs; Vixen does not publish a blast time)
• Stamina-focused compressor. Vixen rates it at a 100% duty cycle at 100 PSI, compared with 25% at 100 PSI for the 150 PSI compressor in its VXO8715/4114B kit
• Thorough documentation. Dimensions, amp draw, CFM, switch points, safety-valve rating, port count and a six-page install guide are all public
• Full safety hardware is included: automatic-reset thermal overload, 250 PSI safety valve, drain valve, 30A fuse and a gauge
• Seven-port tank leaves spare ports for a tire-inflation line or other onboard-air accessories
• Vixen hosts a sound clip of the horn on the product page, so you can hear the tone before buying

Cons

• No decibel rating at any distance, from Vixen or the Amazon listing
• One trumpet means a single note, not a train-horn chord
• Expensive for one trumpet. At about $271 it costs more than Vixen’s quad-trumpet kits with smaller air systems
• Vixen lists the tank at “150 PSI, max 200 PSI” while the switch cuts out at 200 PSI, so the system routinely runs at the tank’s stated maximum
• 23A draw and a 30-lb listed kit weight mean real wiring and mounting work; the guide recommends professional installation
• 12-month warranty with buyer-paid shipping on claims

Alternatives

• Vixen Horns VXO8715/4114B: four black trumpets, a 150 PSI compressor and a 1.5-gallon tank for about $193 on Vixen’s site. You get a chord for less money, but the compressor is rated at only a 25% duty cycle at 100 PSI and the reserve tank is half the size.
• Vixen Horns VXO8210/4124B: Vixen’s entry quad kit at about $171, with a 1-gallon tank and a 90/115 PSI switch. It is the cheapest way to get a four-trumpet chord from Vixen, but its air reserve is far smaller.
• Farbin 18-Inch Single Trumpet Kit: a tankless budget single-trumpet kit for buyers who only want a loud single note and don’t need onboard air.

Within the same family, the black VXO8330B/1164B is $270.57, practically the same price. The VXO8350/1164 swaps in a 5-gallon tank for $321.17. If you want five trumpets on a bigger tank, see our VXO8350B/5901B review.

Install / compatibility notes

The kit is designed for 12V DC vehicles only. The installation guide states that the system must be wired to a 12-volt DC source, even though the horn’s solenoid itself is rated 12V/24V. Expect to drill. The horn, compressor and tank each mount with bolts, and the guide warns against mounting any component on plastic or other flexible material.

1. Plan placement. Choose a dry spot for the compressor, as close to the battery and as far from exhaust heat as practical. The 25” horn needs a rigid sheet-metal or frame surface. The tank (22-¾” long) needs reachable ports. See our guide on where to mount a train horn compressor.
2. Plumb the air. Thread the braided compressor hose into the tank’s ¼” NPT inlet without rotating the inline check valve. Then run the 3/8” line from the tank to the solenoid using compression fittings, sealing all threads with the supplied tape.
3. Wire the compressor. Use 12-gauge or heavier wire. Connect the red lead to an ignition-switched 12V source, run the black lead through the pressure switch, then ground it. The compressor draws 23A and is protected by the supplied 30A fuse. Our amp draw and wire gauge guide has more detail.
4. Wire the horn. Use the included button with a 10A fuse (not supplied), or tie into the factory horn circuit after checking its polarity. The guide walks through both methods.
5. Leak-check and maintain. The compressor should stop at 200 PSI. If it doesn’t, find leaks with soapy water. Vixen recommends draining the tank weekly and cleaning the washable intake filter every two months in dusty conditions. Our tank draining guide covers the drain routine.

Because the switch keeps the tank between 170 and 200 PSI, the system runs hotter and at higher pressure than 150 PSI kits. Vixen’s 100% duty-cycle rating is quoted at 100 PSI, not at that operating range, so treat continuous running near 200 PSI as unrated. If the thermal overload trips, the guide says to cut power and let the unit cool for about 30 minutes. Our compressor duty cycle explainer shows why the rating’s pressure matters.

Before you install, check your state’s rules for aftermarket horns in our legality guide.
