  • These air intake manifolds have similar dimensions and structure. They have a length of approximately 70 mm. The only difference in outside design is that the LS6 has a flat bottom. Being this identical to one another is an important design feature. It allows the parts to be easily replaced in case of damage or to upgrade to a better version.
  • The LS6 is a one-piece Nylon manifold. The structure and material offer a considerable durable product. It is easy to maintain and clean. When done regularly and properly, these simple processes increase the lifespan of the LS6 considerably. It is important to remember that cleaning the air intake manifold also avoids damage to the engine of the vehicle.
