This S&B cold air intake kit is specifically designed for the 2003 - 2007 Dodge Ram with a 5.9L Cummins engine. Engineered to minimize air restriction, it provides 42% better airflow than the stock intake. The fully enclosed airbox protects the filter from dirt and keeps out engine heat. Our silicone filters and couplers are made of premium rubber. They seal better, last longer, can handle up to 400F without cracking or tearing, and won't slide off the tube. S&B invests a lot in engineering intakes to ensure your engine runs well with stock calibration or enhanced tuning. This kit avoids check engine lights by maintaining proper airflow mapping of the Mass Air Flow Sensor. Part Number: 75 - 5094. Features include a bolt - on install, 42% more airflow, 99.51% efficiency, a one - piece air box to keep out heat, a clear lid for a great look, a secondary air inlet to increase airflow, and a plug for those who prefer the stock fender inlet. The secondary inlet also lowers restriction for better performance.

Using this S&B cold air intake kit is easy. First, make sure your engine is cool before starting the installation. It's a bolt - on install, so you can simply follow the included instructions to attach it to your 2003 - 2007 Dodge Ram with a 5.9L Cummins engine. When it comes to the secondary air inlet, if you want more airflow, leave it open. If you prefer to use only the stock fender inlet, just plug it with the included plug. As for maintenance, check the filter regularly. If it gets dirty, clean it according to the cleaning instructions provided. Also, make sure the silicone couplers are in good condition and properly attached. Avoid using harsh chemicals on the filter or the airbox. Keep your intake kit in good shape, and it will keep your engine running smoothly.
