Sinister Diesel Intake Resonator Cover Plate (SDRSNTRDLML) for 2011-2016 Duramax 6.6L LML

Enhance the appearance and performance of your engine bay by replacing the bulky plastic intake resonator box with a sleeker, more durable cover. Not only does this upgrade give your engine a cleaner, more streamlined look, but it also helps eliminate the risk of cracks commonly found in older or lower-quality plastic components. These cracks can allow unfiltered air to enter your intake system, potentially leading to reduced engine efficiency and long-term damage. By upgrading this part, you ensure a more secure, sealed intake path—promoting better airflow and protecting your engine from contaminants.
