First talking to shop yesterday, they paid around $89.00 for a Countach oil filter. EVERYBODY Lamborghini DOES NOT make oil filters. The filters are made by companies like BOSCH, FRAM, PUROLATOR, HASTINGS, etc, etc. You can find a filter at places like Auto Zone, etc, etc. usually around $20.00 This filter also fits ALL the Diablo and US Spec LM002. So it is up to you if you want to pay $89.00 for a filter. NEXT, NO roller/ball bearing on the Countach is made by Lamborghini. The bearings are made by SKF, BOWER, BCA, etc etc.. For instance a rear wheel bearing I needed several years ago was Lamborghini priced around $300.00 I found it around $80.00. Brake pads BMW 5 ,6, 7 series 1976-1982 FRONT PADS ONLY AUTO ZONE around $20.00 unless you are tracking your car, they are more than adequate. Need caliper BMW FRONT ONLY 5,6,7 series car 1976-1982. The front caliper will work on the rear of the Countach. The caliper will also work in the front of the Countach IF, read IF you take the spacer from your original front caliper and put it in the BMW front caliper. This is just part, I will try to up date this often, when I think of other parts.
