With the M-Spec now discontinued, the LS-Spec takes over the line with the same exact piping and core sizing. However, the core is a Tube-Fin Design like the V-spec and R-spec. The tube-fin design is more aerodynamic and allows air to flow more freely through the core with less turbulance. This core is rated for up to 500hp. Anything higher we recommend the Vspec or Rspec.

R-Spec is tube and fin. V-Spec has tubes and fins on the outside but there are no fins inside the tubes. It has a different pattern designed for more airflow so it is a "hybrid" core.
Got any pics of inside the LS-Spec core?
