Mahle MS Piston Set Honda H22 Gold Series 87.25mm Bore 90mm Stroke 143mm Rod -7cc 9.0 CR 22mm Pin

Mahle's Gold Series pistons start with a 4032 aluminum alloy, chosen for its strength and ability to handle higher temperatures and pressures compared to softer alloys. This material is well-suited for performance builds where reliability under stress is key. These pistons are specifically machined for the Honda H22 2.2L engine, featuring an 87.25mm bore and a -7.0cc dish volume, which helps achieve a 9.0:1 compression ratio when paired with a 90mm stroke and a 143mm connecting rod. The 22mm wrist pin diameter is standard for many performance applications, ensuring compatibility with a wide range of connecting rods.

The design incorporates a 31mm compression height (CH) and a total piston weight of 296 grams, which are important considerations for engine balance and overall performance. Mahle's manufacturing process for the Gold Series aims for tight tolerances and consistent weight distribution across the set, which is crucial for smooth engine operation and longevity, especially in modified engines. This piston set is a solid option for rebuilding or upgrading your H22 engine, offering a good balance of performance and durability from a well-known manufacturer.

It's important to note that this piston set is not CARB approved and cannot be shipped to California. Always refer to the manufacturer's detailed installation instructions for proper fitment and assembly procedures, as precise measurements and component matching are critical for engine builds of this nature.
