Product Description
BMW B48 Piston Set - ItalianRP IRPP034DA
Italian Rods and Pistons brings their signature precision and craftsmanship to the BMW B48 engine platform with a lineup of forged pistons designed for serious performance builds. These pistons are manufactured in Italy using aerospace-grade 2618 aluminum, offering exceptional strength under extreme pressure and temperature—ideal for high-boost or track-focused B48 setups. Each piston is CNC-machined for perfect symmetry, and the kit includes ultralight wrist pins and premium ring sets. Whether you're running a stock bore or looking to overbore for displacement gains, IRP offers only one size of 82.0mm, with custom compression ratios available to match your turbo and fuel goals. The piston is paired with ItalianRP's IRPR502 connecting rods and can be found here.
Options include standard 10.1:1 compression for drop-in replacements, as well as OEM and 9.5:1 setups for high-boost, E85, or methanol-fueled builds. Piston crown designs are optimized for direct injection and combustion efficiency, with valve reliefs that accommodate both OEM and aftermarket cam profiles. Every set is engineered with skirt coatings for reduced friction and noise, and optional hard anodizing is available for extreme-duty applications. Whether you’re chasing quarter-mile records or building a reliable street monster, Italian Rods and Pistons gives your B48 the forged foundation it needs.
