The ARM B58 Intake isn’t just another lookalike B58 intake — it’s engineered to outperform. Featuring full 3.75” T6061 aluminum piping throughout, it stands as the largest B58 intake on the market, delivering more airflow to meet the demands of stock, tuned, or fully built B58 engines.

When paired with the ARM B58 Turbo Inlet, this system forms a complete induction solution that helps your B58 breathe easier, spool faster, and support higher horsepower levels.



CONSTRUCTION

At the heart of the ARM B58 Intake is a massive inverted air filter, providing 186 cubic inches of surface area — allowing superb airflow while maintaining impressive filtration thanks to its multi-media filter material.

The filter is shielded from excessive engine heat by a durable aluminum heat shield, which comes standard with a powder-coated black cover or an optional clear cover for a striking engine bay look.

The 3.75” T6061 aluminum MAF pipe flows directly to the turbo inlet, significantly larger than OEM and many aftermarket options, delivering more unrestricted airflow to the turbocharger. The system uses a 6-layer reinforced silicone coupler to connect seamlessly to either the factory turbo inlet or, for maximum performance, the ARM B58 Turbo Inlet.








The T6061 aluminum MAF pipe is a full 3.75" throughout, 14% larger than OEM and similar aftermarket intakes for the B58, providing more airflow to the B58's turbo. 



The ARM B58 MAF pipe is connected to the B58 inlet via the 3.75" 6-layer reinforced silicone coupler.  The ARM B58 Intake is designed to connect to either the OEM turbo inlet or for maximum airflow the ARM B58 Turbo Inlet.

Good purchase
Style: 3 Pound, Pair
These are just the right weight for me to start gaining muscle back in my arms, after a large weight loss. They are of good quality, they are covered in a nice rubber like coating that is soft to the touch. They are small enough that i can take them with me when I travel. My dog has got hold of them a couple times and played with them, and they held up just fine without any damage.

Solid, grippy, and they don’t roll away!
Style: 10 Pound, Pair
I bought these because I’m finally trying to build a consistent home workout routine and didn't want to drop a fortune on name-brand weights. I’ve been using this 10lb pair for about a month now for everything from overhead presses to lunges, and honestly, they’re exactly what I was looking for. The Pros: • That Neoprene Grip: The coating is fantastic. Even when my hands get pretty sweaty halfway through a workout, I don’t feel like I’m going to drop them. It’s a much "softer" feel than cold metal or hard plastic. • The Hex Shape: This is a small detail that makes a huge difference. Since the ends are hexagonal, they don't roll across the floor when I set them down between sets. They also stay put if I’m using them for "renegade rows" or floor work. • Compact Size: They aren’t bulky. I can easily shove them under my bed or in the corner of the closet when I’m done. • No Weird Odor: I was worried they might smell like a tire factory (which happens with some rubber-coated weights), but these had almost no scent right out of the box. The Cons: • Handle Diameter: The handles are a little on the thicker side. I have medium-sized hands and it’s fine, but if you have very small hands, they might feel a bit chunky to wrap your fingers all the way around. • Color Scuffs: The navy blue looks great, but if you clank them together or drop them on concrete, the coating can scuff or show dust pretty easily. The Verdict: If you just need a reliable set of weights for HIIT, Pilates, or general strength training, these are a no-brainer. You're basically getting gym-quality equipment for a fraction of the price. I’ll probably be back for the 15lb set in a few months!

Simple, Comfortable, and Exactly What You Expect
Style: Rack with 3 Pairs (5, 10, and 15 Pound)
These are pretty much exactly what you want from a set of dumbbells — simple, functional, and no nonsense. The neoprene coating gives them a comfortable grip and keeps them from feeling slick in your hands, especially during longer workouts or if your hands get sweaty. The coating also helps keep them from banging up floors or making as much noise compared to bare metal weights, which is nice if you’re working out at home. Weight accuracy seems fine for general fitness use, and they’ve worked great for things like accessory movements, shoulder work, lighter presses, rehab-style exercises, and general muscle toning. The shape also helps keep them from rolling around everywhere when set down. They’re not fancy, and they’re not trying to be — they’re just dependable dumbbells that do what they’re supposed to do at a fair price. If you want straightforward hand weights for home workouts without overthinking it, these are a solid buy.

Reliable, Comfortable Dumbbells I Actually Use Every Day
Style: 12 Pound, Pair, Style: 12 Pound, Pair
I’ve been using the Amazon Basics Neoprene Dumbbell Hand Weights daily, and they’ve honestly been perfect for my routine. Whether I’m doing a quick morning workout or adding resistance to a longer session, these have held up really well. The neoprene coating makes a big difference—it provides a comfortable, non-slip grip, even during longer workouts or when my hands get a little sweaty. They’re also easy to clean and don’t have that strong rubber smell some weights can have. I really appreciate the hex shape too. They stay put when I set them down (no rolling across the floor), which makes switching between exercises quick and frustration-free. The weight feels evenly distributed and well-balanced, so movements feel controlled and smooth. Overall, these are simple, no-frills dumbbells that just work. If you’re looking for reliable hand weights for everyday use—whether you’re a beginner or just need something dependable for home workouts—these are a great choice.
