Frequently Asked Questions
Q: Will a cold air intake really help my LMM Duramax?
A: Yes, it can help improve airflow and throttle response. The biggest gains usually show up in how the truck feels under load, not just in peak numbers.
Q: Is a dry filter better than an oiled filter for diesel trucks?
A: It depends on your preference. Dry filters are usually easier to maintain, while oiled filters may appeal to owners who want a different style of filtration.
Q: Do I need a tune after installing a cold air intake?
A: Most intake kits do not require a tune. Still, a tune can help if you want to get the most from your full setup.
