i have an 89 325i it was an automatic car originally.it now has an 86 325es tranny and rear.i was going to replace the intake boot on it but there are 2 different intake boot choices 1 for an auto tranny and one for a 5 speed tranny.do i have to replace the intake boot with the auto tranny one or the 5 speed one now that its swapped.it has a slight idle problem and i was going to replace a few hoses and the intake boot but now im stuck.dont know if auto intake boot is having any effect on the idle.
