Sinister Diesel Intake Horn for 2020-2021 GM

NOT FOR SALE IN CALIFORNIA Add durability and longevity to your Duramax's air system. Our Sinister Diesel Intake horn is designed to increase air flow, using 3.5", mandrel bent aluminum tubing. Precision designed, a machined billet flange gives your turbo a more consistent and healthy dosage of air. This allows for optimal flow to the turbo which eliminates turbo surging. Our intake horn is made from 6061 aluminum which is far superior to the factory plastic inlet. That means no cracking from weathering or from hard strain while under vacuum. This inlet cracking is a known problem of the stock part and can cause detrimental issues to your turbo. Not only is this part providing healthier airflow but will give you the security of long life needed for your truck. Feel secure with your air system under all conditions, daily use, towing, and much more.
