Just wondering what is the best type for this car? Ive read on a few websites including then here that they will reduce power and more then anything do nothing for the car expect make noise. All replies listened to and are welcomed as i still dont much about the car
 
i have a HKS BOV fitted and i dont have any problem with it.

There is plenty of power left in mine even with the BOV
