According to manufacturer specs, it is optimized for cams with lift up to 0.550 inches, making it a good match for stock or slightly upgraded LS engines. Owner feedback indicates that it provides a solid torque bump in the 1500-4000 rpm range, improving drivability. The cast aluminum construction is durable, and the polished option adds aesthetic appeal.
However, this intake is not designed for high-performance cams or forced induction applications; owners have reported that it becomes a restriction above 5000 rpm. We recommend it for budget street builds where low end torque is the priority. If you plan to upgrade to a larger cam or add boost, look elsewhere. Installation is straightforward, but some users have noted that the included water neck may require additional sealing.
- Designed for mild street cams up to 0.550" lift
- Cast aluminum with polished finish option
- Includes gaskets, bolts, and water neck
Pros: Good low end torque with mild cam profiles; Polished finish looks great under hood
Cons: Not suitable for high lift cams or forced induction
