Engine Blueprint Series LS4 T-shirt or Hoodie
The LS4 engine is a Gen. 4, 5.3L, aluminum small block engine used in GM cars between 2005 and 2009. It is unique because it was the only LS engine used in FWD vehicles. The LS4 had cathedral port cylinder heads and used Active Fuel Management
The LS4 is unique in the LS engine family because it was a transverse-mounted engine used only in front-wheel drive (FWD) cars from 2005-09, namely the Pontiac Grand Prix GXP, the Chevy Monte Carlo SS and Impala SS, and the Buick LaCrosse Super.
We offer this in our favorite vintage tri-blend which is ridiculously soft and runs a size small, as well as a 100% cotton t-shirt and 50/50 hoodie that both fit true to size.
