Anyone who has been around engines for any length of time understands the need to match intake manifold runner length to the needs or requirements for the engine you are building. As a general rule, longer intake runners lend themselves to more torque at lower rpm levels, while shorter runners help make high rpm horsepower.
But an intake manifold isn’t typically something you swap out regularly depending on what type of performance you are looking for on a particular day. That’s why FASTS’s new LSXR composite intake manifold for LS engines is so revolutionary. Instead of being stuck with a single runner length, the LSXR intake manifold makes it easy to change the runners depending on your situation. For daily road driving you can go with longer runners for a nice, torquey ride. But you can still easily swap them out for shorter race runners for a day at the track.
