World leading Carbon Fiber airbox manufacturer GruppeM, have re-developed and raised the bar for RAM Intake design for the R35 GTR intake kit.
With hand crafted carbon fibre intake ducts catching air from the front of the car and ramming it into the re-crafted airboxes, you'll notice the improvement in the mid to high RPM range. This is thanks to the ram air design and heat shielding properties that Carbon Fiber provide over plastic.
Arguably the best intake kits in the world, GruppeM RAM Air intakes are designed, tried, tested and all return a better than stock, and in most cases, a better than the competition performance result. Made primarily out of Carbon Fiber, housing a re-usable M's Power Filter by K&N, these provide great flow with great heat-shielding abilities that are only amplified through the RAM air intake setup.
GruppeM kits will ship direct from Japan and are deliverable to most of the world. Please be aware, kits are every now and then, made to order and can attract a 3-4 week day process time. Well worth the wait.
