{"product_id":"ie-spec-mahle-forged-piston-set-82-5mm-bore","title":"IE Spec Mahle Forged Piston Set, 82.5mm Bore","description":"The IE Spec Mahle Pistons are custom-spec, high-performance pistons designed in collaboration with Mahle for VW\/Audi 2008+ 2.0T TSI engines. They are available in two bore sizes: 82.5mm, which is the stock size and allows for direct drop-in installation without needing to remove the block, and an 83mm (.5mm overbore) option that increases displacement to 2008cc and requires the block to be bored and honed to precise specifications for optimal fitment and performance.\n\nKey features include a 22mm wrist pin designed for use with IE rods, OEM fitment and wear characteristics, and a lightweight forged alloy construction. The pistons utilize Mahle's proprietary low-expansion 124P alloy, offering a balance of strength similar to 2618 alloy and low-expansion properties of 4032 alloy for quiet, smooth operation. They also incorporate a Grafal anti-friction skirt coating to reduce friction and wear, and hard anodized ring land areas to prevent micro-welding. Tightly controlled ring-to-groove clearances minimize blow-by for increased efficiency.\n\nThe pistons are engineered with compression ratios closely matching the factory 2.0T TSI (EA888 Gen 1, 2, \u0026amp; 3) engines. Specific compression ratios are 9.5:1 CR for Gen 1 \u0026amp; 2 (2008-2014) and 9.3:1 CR for Gen 3 (2015+). The design includes a factory-style dish on the crown, essential for smooth operation with the direct injection system, and oil squirter notches for clearance-free fitment.\n\nThese pistons require aftermarket connecting rods with a non-tapered 22mm small-end to match the included high-strength 22mm German steel wrist pins. IE offers compatible connecting rod options. The product is designed for VW MK5, MK6, MK7\/MK7.5 and Audi B8, C7, 8P, 8J, 8V, 8S models with the 2.0T TSI engine (Gen 1, 2, and 3).","brand":"IE \/","offers":[{"title":"Default Title","offer_id":52688801628472,"sku":"MAH-PVN1","price":997.49,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/664719427.webp?v=1784896479","url":"https:\/\/store.motormia.co\/products\/ie-spec-mahle-forged-piston-set-82-5mm-bore","provider":"MOTORMIA","version":"1.0","type":"link"}
