Own a Nissan GT-R? Need a manifold capable of producing 1000hp+? We've got you covered. Wilson Manifolds has developed the secret to the unleashing the full potential of the stock GT-R Manifold. Every inch of the factory intake has been tailored and modified with big boost and power in mind. The GTR intake has adjusted runner length & plenum volume plus completely ported and polished upper & lower manifold sections. Even though the plenum is sectioned open to change plenum volume & the runner length is changed, the factory crossover mounts up & the throttle body location stays the same so that the turbo pluming does not need to be changed.
