The test was done back to back on the same day with all variables staying consistent through both tests.
Ls6 intake vs sheet metal intake.
Compared to the ls1 the ls6 offered an additional 22.
Designed as a factory upgrade for the ls1 the ls6 intake once again proved its reputation by significantly improving the power of our 6 0l.
The test was run on a 5 3l ls with a comp cam and valvesprings so it could handle some rpm and boost.
In this video it is an intake manifold shootout between the factory ls6 long runner intake and an aftermarket short runner sheetmetal intake.
