hi all, i just have a question. i did a 24valve swap to my 325i 1988 and i changed the thermostat to 80 degree and the tempreture sending unit to 80 degree too, my tempreture gage sits on the last line just right befor the red line. im just wondering if the three port aut fan switch from 318 with 80 degree will fit and help drop the tempruture down:dunno: also i have aproplem with idle, the car on the 4th gear feels like it in the secod it kinda loud? i installed a cool air intake filter i dont know if that whats cousing the problem?
