Excellent product made by ARP! BMW does not sell a replacement 11mm connecting rod bolts for the 2001-2003 M3. Your only option is someone else's used bolts or a complete replacement connecting rod set with new bolts, but the latter is a very expensive option. ARP bolts is a great, cost-effective solution which is also an upgrade over the OEM BMW bolts. BMW M3 oil pan gaskets leak all the time and rod bearing wear is very common on the M3 S54 engines. When replacing the oil pan gasket or performing a rod bearing replacement is a perfect time to also upgrade the rod bolts.
