e39 530i m54改裝4孔噴油嘴
請教有人e39 530i m54改裝4孔噴油嘴嗎,原來是2孔升級bosch4孔 24lbs/hr, 267cc/min at 3BAR
M54B30 only
BMW Part No: 13 53 7 546 245
Manufacturer: Siemens
Manufacturer Part No: 1439800
Flow rate: 244cc/min or 23.2lbs/hr at 3 bar (43.5psi)
315cc/min or 30.0lbs/hr at 5 bar
從帳面上看好像差不多,但多2孔是否會運轉品質更佳,油門反應好,油耗不知道會不會差很多
