What do all you guys think about BOV's on an Auto Z. My Z came from japan with a pair of HKS supers on it, I have heard and read a lot of contradicting information on BOV's on an auto, Is it harming my car? Can the air still escape properly? Dose it make any difference to the cars health/performance? Really keen to get a difinitive answer on this.
I have them.......>> Nissan obviously decided that the auto needed them because they fitted them with the same valves they put on the manual cars.
Even autos have to close the throttle occasionally...... so the purpose of the BOV's is the same. It's just that they will be more beneficial on a manual because you are closing the throttle a lot more often.
