Let your truck breathe with a cold air intake kit! Our BHAF (Big Honkin' Air Filter) cold air intake kit features a beautiful #4 finish stainless steel or "silver vein" powder coated shroud. This shroud keeps the air filter dry and helps to lower intake temperatures. Captive nuts and stainless steel bolts make installation and service easy. We also think it looks pretty great under the hood!
PLEASE READ BEFORE ORDERING
This kit may or may not work with other popular BHAF intake kits, but it certainly will not work with stock intake tube. Air filter elements, pre-filters and tubing kits are optional add-ons to this kit.
Air Filter Element Info:
Dimensions: 10.5" diameter, 11.8" height, 4.00" inlet ID
Below are filter element part numbers that are compatible with our kit:
Donaldson B105006 (Available from Five Nine Fab)
Fleetguard AH19037
John Deere PMAH19037
WIX 42790
Napa 2790
Baldwin PA2820
Carquest 87790
Prefilter Info:
We also offer an Outerwears Performance Products prefilter to compliment your intake kit. We believe the prefilter pays for itself by keeping large debris out of your air filter, significantly extending filter life without sacrificing airflow.
Tubing Kit Info:
Our tubing kit features a mirror finish 45º aluminum tube, quality 45º silicone boot, and spring-loaded t-bolt clamps, all sourced from Vibrant Performance and Clampco USA. No expense has been spared to build this kit, and it these components are listed for the minimum advertised price. This kit will fit a wide variety of turbo configurations, as long as they're mounted in the stock location. Some trimming to the 45º silicone boot may be required in some applications. Instructions for trimming are included.
Replacing your stock corrugated rubber tube with our tubing kit will increase turbo noise, improve airflow, and put a smile on your face!
Notes:
No drilling required
Tubing Kit Boot may need to be trimmed

The Blue boot in the photos is no-longer available from Vibrant. We're looking for an alternative!
I couldn’t be happier with the Five Nine Fabrication BHAF kit for my 1st Gen Cummins. The quality is outstanding—everything is well-built, fits perfectly, and installs without any headaches. The kit gives the engine bay a much cleaner look while providing excellent airflow to the turbo.
All the hardware included was top-notch. It’s obvious that Five Nine Fabrication puts a lot of thought into designing products that actually fit and perform the way they’re supposed to.
If you’re looking to upgrade your intake setup, I highly recommend this BHAF kit. Great product, excellent craftsmanship, and definitely worth the money!
This was probably the easiest Intake install that I have ever done. Fit and finish was flawless. Really, a big pick up in turbo response. Helps the driveability of the truck immensely. The turbines communicative without being intrusive. It’s really nice .
Quality true cold air system for a platform with few options. Retains all stock functionalities (factory jack, tire iron, etc.). The only thing to note is that this will not be nearly as easy to install/remove as a stock system, the intake tube in particular. Otherwise, looks great, sounds great, feels great.
Beautiful part really finishes out the truck. This went in a 81 model truck so it took some light trimming at the wheel well. Shouldn’t have any trouble getting enough air now.
Mounted up easy. Looks great!! Will be ordering more first gen dodge products as they make more👍🏼👍🏼 great customer service as well, thought I was missing air filter but when I reached out I was swiftly responded to and informed the filter was a separate package. (Keep in mind your filter may or may not be in a separate shipment) all around 10/10 would recommend!!
Shipped quickly and installation was straightforward. Included instructions were well written and easy to follow. Cleaned up the engine bay plus the benefit of a bigger filter and better flowing intake tube.

Justin,
Thank you for your review. I think you're correct about the directions. I'll be working on writing some better instructions in the near future.

The kit is great quality, and definitely worthwhile for the price. My only complaint is that at my higher RPMs of every gear, it sounds like there’s a turkey in my air intake box. Re installed the original intake and box and the sound goes away, not sure if I did something wrong. All calmed are tightly on. Likely going to stick with the original air intake, as the truck and engine are damn near all original.

Hello Patrick, Thank you for your review! I'll look into the directions and see what we can do to improve them. Are there any specific questions or suggestions you have?
Super fast shipping great price and everything seems to good quality. Have not had a chance to install yet.
The guys at Five Nine were Great not only do they sell a quality product but the customer service was out of this world. I spoke with Randy the owner and explained what we were doing and he really help come up with a great solution. I ordered this on December 17, 2025 for a Christmas present for my son. Randy personally shipped it out the same day and followed up to make sure I received it before Christmas. I highly recommend this company and their excellent products.
Installed fairly easy and looks good. I haven't ran the truck yet though, I'm doing a transmission swap and wanted to put this in while I was waiting for parts. I've had a BHAF for years but I like how this kit hides the filter. Makes it look clean.
Clamp for the air filter to the intake tube was too small wouldn’t work at all.
I picked up a larger clamp. That issue was solved. Silicone boot won’t clear the alternator it will be fine in the short term long term fix would be to run a half inch spacer between the exhaust manifold and the turbo.
I have a 3 piece manifold and an Hx35w.
I think this is a my setup issue not a product issue. More to follow. If you’re interested I can send pictures.

Over all looks nice seem to improve flow over the stock box and tube.
Thanks.

This customer and I discussed the issue and decided that I must have shipped him one of the wrong clamps. The other issue is likely related to the aftermarket exhaust manifold. Please feel free to reach out directly to us if you ever have an issue with one of our products.
Awesome looking cleans up the engine bay good quality and easy to install
