This is a GN1Performance "AC DRIER HEAT SHIELD" for a 1986 or 1987 Buick Grand National, T Type, Turbo T, or GNX 3.8 liter turbo V6. This is a nice item for those who are running A/C in their cars and need it to perform at its absolute best. This item keeps the heat away from the Drier and helps keep your A/C as cool as possible.
