Features and Benefits
The coolant hoses play a crucial role in your Miata NB1 cooling system. Over time, these rubber hoses are exposed to high temperatures, engine heat, and chemicals that contribute to the aging process and lead them to develop cracks, leaks, or become soft and mushy. The HPS Performance High Temperature Reinforced Silicone Ancillary Bypass Coolant Hose Kit (part number 57-2157-BLK) is designed to deliver ultimate durability and resistance to wear and tear for your 99-00 Mazda Miata 1.8L thermostat bypass, throttle body, air control valve, and oil cooler hoses. These multi-ply reinforced hoses can withstand high temperatures of up to 350F and are less prone to cracking, swelling, or becoming brittle compared to traditional rubber hoses. In high-performance or racing applications, silicone hoses are often preferred as they are less likely to collapse under suction or burst under pressure, providing better reliability in situations where engine performance is crucial. Engineered using OEM data, these hoses are made to directly fit into your vehicle without the need for any modifications. This kit comes complete with 100% stainless steel hose clamps designed to be safe on silicone hoses and provide a leak-free seal.

Remark: Silicone hose water permeation rate is 10 to 15 times greater than standard EPDM rubber hose. Checking water level regularly is highly recommended when silicone coolant hoses are used in a daily driving vehicle.

Nice once put together.
Color: Black, Size: 88"- 4 Panel
I really enjoyed these ones. They got put up, putting them together was a two-man task and not very easy at all. They work really good. They're very heavy duty. You can hang things on them. I kick mine out of the way and they work like a charm!

Great value, perfect for our infant room!
Color: Black, Size: Standard - 4 Panel
Great product, sturdy design and easy to build! It is a fairly light weight item, which aids in the maneuverability of the divider. The color was as described and is dark enough to block the light from our sleeping infants! I do love that you are able to see through the slats and see the child sleeping- if you are looking for something with MORE privacy, this is not it. It has great coverage area and is dark and a wonderful value for the price, however, you are able to see through the areas where each panel connects!

Don’t waste your money or time!
Color: White, Size: Standard - 4 Panel
Don’t waste your money. The instructions make no sense and the metal poles are either sized wrong for the product or screw holes are incorrectly placed, but no two poles matched in size and placement making it impossible to put this together without the panels being warped. No matter how I tried to switch the poles to see if I had them wrong, they always turned out warped and incorrectly fit. I finally gave up and threw everything out - I wasted $50 on this junk and because I didn’t try to put it together immediately after I bought it, it is way too late for a refund. Lesson learned!

Sturdiness
Color: Black, Size: Standard - 4 Panel
Not so sturdy. It worked well for its intended job, but, it has to be secured to the floor for long term use.
