Our velocity stacks are designed to optimize and maximize the entry of air flow into the vehicle's induction system. In short, the low velocity air flow is turned into a smooth and high velocity intake charge. High velocity intake equals more horsepower. Our stacks are made from high quality 7075 billet aluminum for rapid heat dissipation, eliminating heat further improves performance. Our stacks are also hard anodized for a long lasting finish.
- This velocity stack has 4" opening on the pipe side and is 6" on the bell side.
- Think of this as an EASY 3-5hp gain on naturally aspirated vehicles. Gains can be even higher depending on your setup. Perfect for race days.
