IRP connecting rods, AUDI S6 , S7, RS6, RS7 (4.0TT)

Italian RP (IRP) reinforced connecting rods for racing and performance use

The renowned Italian IRP connecting rods are available in three different strength levels depending on the application.
These rods are not the cheapest on the market, but they are engineered to withstand extreme loads such as Stage 3 and Stage 4 builds or demanding motorsport use.
They directly replace the OEM components and are built to handle high boost, heat, and RPM reliably.
