Aftermarket intakes on the 3.0 Duramax generate a lot of questions — and a lot of misinformation. In this episode, I answer the most common intake questions owners ask, including power gains, MAF accuracy, EGR interaction, MPG changes, intake design, and why sound doesn’t always equal airflow. This is a data-first, no-hype discussion focused on how the 3.0 Duramax actually uses airflow and sensor data to make decisions.https://www.demonworkshop.com/products/2020-2025-gm-3-0l-duramax-diesel-fuel-cap-173001000Amazon Fuel Cap: https://amzn.to/4iSznKiACDelco Fuel Filter: https://amzn.to/3QFfXex3.0 Duramax Oil Change W/ PPE Oil Filter: https://amzn.to/3qmLR6o3.0 Duramax Oil Change W/ ACDELCO: https://amzn.to/3QtmDO5PPE OIL FILTER: https://amzn.to/3JP9j22 - BE SURE YOU ARE BUYING FROM PPE ONLY - CHECK SELLER NAMEFuel Filter Socket: https://amzn.to/4b52BkYFuel Filter KlickWrench Socket: https://amzn.to/42arKH6Aluminum Fuel Filter Cap: https://amzn.to/3FZir28K&N Air Filter: https://amzn.to/3S5sLvqK&N Intake: https://amzn.to/4b6oy35K&N Fuel Filter: https://amzn.to/4b6Ux3ihttps:/www.maxl.com/demonworks https://www.bankspower.com/demonworksBANKS DISCOUNT CODE "DemonWorks"WEIGH SAFE HITCH: https://www.weigh-safe.com/product/weigh-safe-drop-hitch/?affiliate=demonworksALSO USE Discount Code DW10 at weigh-safe.com www.bankspower.com/DemonWorkswww.duramaxnews.comwww.bankspower.com/demonworksAs an Affiliate / Influencer, I earn from qualifying purchases.
