JE Pistons / SRP · 353225

Description

Features & benefits

• Forged in the USA using 2618 aluminum, yielding tensile strength and minimal thermal expansion
• Pin Fit: The pin bore is precision honed to attain an exact pin clearance. Clearances typically range from .0003 to .0010 between the wrist pin and pin bore.
• Econo Undercrown Milling: Creates a lighter, more durable piston with uniform deck thickness in critical areas, offering excellent value through efficient machining.
• Skirt Coat: Skirt Coat reduces friction and wear on piston skirts and cylinder walls while simultaneously reducing operating noise
• Ultra Groove: Specialty ring groove machining process that provides near perfect groove flatness and surface finish. Tolerances are held to the millionths of an inch.
• Designed specifically for Porsche 2.2L Aircooled Engines. To provide optimized performance durability
• Proprietary Forged Side Relief (FSR) forging design minimizes friction and power loss with reduced skirt width and saves additional weight with a shorter wrist pin
• Includes high-quality wrist pins, locks, and JE Pro Seal premium piston rings
• Made 100% in the USA
• Accumulator Groove: A specialty groove between the top and second ring provides added volume for blow-by gases. This helps reduce pressure between the rings, improving top ring seal and minimizing ring flutter at high cylinder pressures.
• Contact Reduction: Reduce the amount of contact area against the cylinder wall when the piston "Rocks over". Contact reduction also serves to disrupt the flame travel into the crevice area causing a reduction in detonation.
