Conrod Bolt Set fits Mazda B6 1.6L & BP 1.8L DOHC Miata, M9

Because factory connecting rods (or aftermarket versions of OEM rods) are used in a variety of applications from rebuilt stock motors to modified powerplants used in circle track, marine and drag racing engines - including those with superchargers and/or nitrous oxide injection systems - ARP offers replacement rod bolts in three different models. All of them are substantially better than the stock OEM and most aftermarket bolts.
