Wiseco ASC-07446 BMW M54B30 -7.3cc Dish Forged Piston - Single (For KE325M845)

The Wiseco ASC-07446 is a single replacement forged piston for the BMW M54B30 3.0L 24-valve inline-six engine, sold individually as a direct replacement component for the KE325M845 six-piston set. With a 84.50 mm (3.3268 in) bore diameter, -7.3cc dish crown profile, and a 1.114 in (28.30 mm) compression height, this piston is precision-engineered to Wiseco's exacting professional-grade specifications.

Key Features:

• 2618 High-Strength Aluminum Alloy – Engineered, forged, and machined in the USA for superior tensile strength and durability under high-stress performance conditions
• ArmorGlide® Skirt Coating – Permanently applied dry-film lubricant that reduces friction, resists seizure, and quieter piston operation throughout the life of the part
• Dish Crown Profile (-7.3cc) – Optimized combustion chamber geometry compatible with the M54B30's 9.0:1 compression ratio target
• Floating Wrist Pin Design – 0.8661 in (22 mm) outer diameter wrist pin for smooth, reliable pin retention
• Precision Ring Grooves – Machined to tight tolerances to ensure proper ring seal and consistent performance
• Fully Machined Crown – CNC-machined crown features for exacting fitment and balance
• Single Piston – Sold individually as a replacement for the KE325M845 piston kit set

Wiseco pistons are manufactured at their state-of-the-art facility in Mentor, Ohio, using advanced forging processes and finite element modeling to maximize strength while minimizing weight. The ASC-07446 is purpose-built for the BMW M54B30 platform and is an ideal solution for engine rebuilds requiring a single replacement piston matched to the full KE325M845 set specification.
