{"product_id":"2zz-forged-piston-set-82-00mm-bore-12-3-1-compression","title":"2ZZ Forged Piston Set, 82.00mm Bore, 12.3:1 Compression","description":"The Mahle MAH-21123-820 piston set utilizes Mahle's forged piston technology and precise manufacturing tolerances to deliver enhanced performance for Toyota 2ZZ engines. These pistons feature an 82mm bore and a 12.3:1 compression ratio, making them ideal for naturally aspirated applications.\n\nMahle's proprietary piston skirt coating, composed of specialized lubricants and iron, significantly reduces friction. This advanced coating allows for installation directly into a stock, unmodified 2ZZ cylinder block without the need for sleeves, offering considerable cost and convenience advantages. Installation involves measuring bore clearance to ensure the block is within specification and filing the rings to size, potentially without removing the engine from the vehicle.\n\nIt is important to note that this coating is not intended for use with cast iron sleeves, as it may lead to a reduced lifespan of the coating. While Mahle has observed excellent results and minimal bore wear in their shop 2ZZ engines, including high-horsepower drag racing applications, forged pistons inherently may produce some noise and result in increased bore wear. Consequently, builders aiming for extreme power levels or endurance racing may still opt for sleeves and alternative piston designs for maximum longevity. The set includes four pistons, four sets of rings, four wrist pins, and eight wrist pin retainer clips. This piston set is not compatible with Nikasil bores.","brand":"Mahle","offers":[{"title":"Default Title","offer_id":52688999350584,"sku":"MAH-21123-820","price":619.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/687437369.webp?v=1784900124","url":"https:\/\/store.motormia.co\/products\/2zz-forged-piston-set-82-00mm-bore-12-3-1-compression","provider":"MOTORMIA","version":"1.0","type":"link"}
