Hi & welcome!.
The 2.7 V6 Delta engine does respond particularly well to `breathing` mods, intake, headers & exhaust.......but the last 2 won`t come cheap, due to the V6 configuration & twin exhaust layout.
Due to the car`s age (almost new) they are hard to justify!.
However, removing the restrictive airbox & intake resonators & fitting an AEM Cold Air Intake Induction System, will give you a nice gain & a healthy induction roar!.
