Callout 17 on BMW’s drawing “Cylinder head Vanos”. Open the drawing →

ISA screw — a genuine BMW part, number 07 12 9 905 121. You will find it under Supplies & Hardware (Group 12). It supersedes the older numbers 07 11 9 900 230 and 07 12 9 902 391, so a part carrying any of them is the same part.

Fits E36 M3 (1995), sedan, coupe and convertible, with the S50 engine.

BMW draws it on 9 drawings, among them Cylinder head Vanos and Oil pan upper part and connecting lines. BMW's catalog calls for four of these at each place it is fitted.

Out of stock. Request it and we will notify you when it is in stock.
