Using these hose clips is easy. First, make sure the hoses and the areas where you'll install the clips are clean. Then, place the clip around the hose and tighten it properly. Don't over - tighten as it might damage the hose. As for maintenance, since they're made of high - quality stainless steel, they can withstand various conditions. But it's still a good idea to check them regularly for any signs of wear. If you notice any issues within the 12 - month warranty period, you can get them replaced. Remember, these clips are designed to fit AS3 Performance and OEM hoses, so use them only with compatible hoses.
