Why is your IR manifold better than others?
HILBORN manifolds are bred from our racing heritage and are designed to make maximum power. Our manifolds are a true individual runner (IR) manifold and are not conversions, instead, they are engineered at the foundry level to accept the EFI components. We have also found that one size doesn’t fit all, so our manifolds are flexible enough to fit engines with unique heads and various deck heights. Also, we offer a choice of butterfly sizes that allows us to tailor the manifold to meet, or exceed, the power expectations of your engine without compromise to drivability. No one gives you more choices than HILBORN.
