Trick Flow Box R-Series Intake Manifold for SBF 302 Based Engines

Trick Flow's® Box-R-Series EFI Intake Manifolds deliver an excellent balance of airflow distribution and velocity to provide big mid- and upper-RPM horsepower gains for ultra-high performance street and race engines running in the 3,000 to 8,000 RPM range.

What we say:

This intake manifold is an excellent choice for high rpm horsepower in a mpfi setup. We have dyno tested this intake manfold versus the long runner style intake. Where the TFS Box "R" stands out versus long runner style efi intakes is the power gains passed 6500 rpm. On our high revving 347 versus other breadbox style intakes the TFS Box "R" series had solid increases of over 12 rwhp in the curve. The Box "R" with a 90mm throttle body and our 4" Power Pipe® is a winning combination. We specifically use this intake manifold on our race top end kits for a reason. They simply work.

This Trick Flow® Box-R-Series EFI Intake Manifolds is silver powdercoat finished. The manifold has a 90mm throttle body inlet and is designed for use on non-EGR engines.
