APR license plate frames and vanity plates are the perfect addition for any APR tuned vehicle! They are made from sturdy and rust-resistant T304 stainless steel. They are thick enough such they won't flop around like throw-away handouts you find in a typical swag-bag at car shows. They feature a fade and scratch resistant black powder coated finish with laser etching for the APR logo. Anti-vibration backside plate tabs keep it firmly in place. Four slotted install holes give you the perfect fitment with a solid connection to the car. The nice hardware hiders give it a clean finish too, hiding your unsightly plate screws. Fitment is universal. Some have said this product will increase the value of the vehicle, while others have made horsepower gains, but we can't comment on either.
