Using the GrimmSpeed Post MAF Hose Kit is straightforward. First, make sure your vehicle is turned off and has cooled down. Refer to the included installation guide for step - by - step instructions. It's designed for easy installation, so you shouldn't need any major modifications. When it comes to pairing it with the GrimmSpeed Dry - Con Panel Air Filter, simply follow the guide to ensure proper fitment. This way, you can get the most out of your intake system without having to make any tuning changes. As for maintenance, check the silicone hoses regularly for any signs of wear or damage. The powder - coated finish is durable, but if you notice any scratches, you can touch them up to prevent rust. Also, keep an eye on the hydrocarbon filter to make sure it's functioning properly, especially if you have a 2022 - 2024 WRX model. If you have any questions during use, don't hesitate to reach out to the manufacturer's customer support.
