Hi guys. Just bought a 335i and want more power. I was looking at just a JB4 and cone filters to start with. Over here it would be on 97ron [93 oct] What sort of figures could i expect?
~ JB4 ~ BMS DCI ~ Active Autowerks Chargepipe ~ Active Autowerks BOV ~
Borla Catback Exhaust ~ Alpina Gearbox Flash
