What is the compression ratio for this piston set?

This Mahle MS Piston Set features a 12.1 compression ratio. This is a notable increase over stock, which can help improve engine power and efficiency when properly tuned.

Are these pistons suitable for all Ford Modular engines?

These pistons are specifically designed for Ford Modular 2-valve or 4-valve engines with a 283 cubic inch displacement. It's crucial to verify your engine's specifications to ensure compatibility.

What does the 'Not CARB approved' note mean?

This means the pistons do not meet California Air Resources Board (CARB) emissions standards and cannot be legally shipped to or installed in California. They also carry a Prop 65 warning.

Product Details

This Mahle MS Piston Set includes eight pistons, designed for Ford 283ci modular engines. These pistons feature a 3.571-inch bore and a 3.543-inch stroke, paired with a 5.933-inch rod length and a .866-inch pin diameter. With a 0cc combustion chamber volume and a 12.1 compression ratio, this set is built for those looking to rebuild or significantly upgrade their engine's top end.

Mahle is a well-known name in engine components, and this set reflects their commitment to well-built parts. The pistons are forged, which means they are stronger and more durable than cast pistons, making them suitable for higher performance applications where increased cylinder pressures are expected. The 12.1 compression ratio is a notable increase over stock, which can lead to improved power output and throttle response when paired with appropriate tuning. Each piston weighs in at 399 grams, contributing to a balanced rotating assembly.

It's important to note that these pistons are not CARB approved and cannot be shipped to California. Additionally, they carry a Prop 65 warning. For optimal performance and longevity, ensure these pistons are installed by a qualified mechanic who can properly balance the rotating assembly and tune the engine to take advantage of the increased compression ratio.
