If your goal is to push your engine’s airflow and performance to the next level, the BTR Equalizer intake series from Brian Tooley Racing brings serious capability to high-RPM builds. Designed with race-inspired features and versatility, these manifolds are ideal for boosted applications, high-lift cams, and engines targeting top-end powerbands.

Each brian tooley intake manifold in the Equalizer family is cast from premium 319 aluminum, CNC-machined runner openings, and includes O-ringed interfaces to boost sealing integrity. Their design focuses on delivering consistent, efficient airflow between 6,000 and 8,000 RPM, making them a go-to choice for engines that live in the upper rev range. A two-piece plenum layout enhances accessibility, and the clamped interface is sealed via multiple O-rings to maintain optimal pressure under load.

What sets the Equalizer line apart is its adaptability: low-profile packaging helps with hood clearance, and multiple MAP sensor locations allow flexible tuning setups. Boosted platforms especially benefit, since the manifold’s flow characteristics help maintain stable air delivery and prevent flow separation under pressure.

When comparing BTR intake options, the Equalizer line offers an excellent balance between design sophistication and real-world performance. Use it when you’re building for power, response, and flexibility rather than just stock drivability.

Browse this category to find the ideal manifold variant for your engine family—whether cathedral-port LS, LS3-style, or square-port configurations—and choose the version that matches your boost, cam, and horsepower goals. The right torque curve and airflow are waiting.
