{"product_id":"ie-spec-82-5mm-piston-set","title":"IE Spec 82.5mm Piston Set","description":"The Mahle Motorsport IE Spec Pistons are custom-engineered for VW\/Audi 2.0T TSI engines, building on a collaboration between IE and Mahle for industry-leading performance and durability. These pistons utilize Mahle's proprietary 142P alloy, which combines the low-expansion properties of 4032 with the strength of 2618 alloy. This allows for tight piston-to-wall clearances, ensuring quiet and smooth OEM-like operation.\n\nEach set includes performance piston rings with a barrel-faced top ring, ductile iron, and a 3-piece oil ring designed to minimize drag and reduce blow-by. The pistons are equipped with 22mm high-strength German steel wrist pins and wire locks, ideal for strength and durability. For optimal performance, these pistons require aftermarket connecting rods with a non-tapered 22mm small-end, such as IE's own connecting rod options.\n\nAvailable in 82.5mm (stock bore) and 83mm (+.5mm overbore) sizes, the 83mm option increases displacement to 2008cc and requires boring and honing the block for precise fitment. The pistons are designed with a factory-style dish on the crown for smooth operation with direct injection systems. Compression ratios are optimized for the 2.0T TSI engine generations: 9.5:1 CR for EA888 Gen 1 \u0026amp; 2 (2008-2014) and 9.3:1 CR for EA888 Gen 3 (2015+), mitigating knocking susceptibility.\n\nFurther enhancing longevity and performance, these pistons feature Grafal anti-friction skirt coating for reduced friction and quiet operation, along with phosphate coating for initial startup lubrication. Oil squirter notches are integrated for proper fitment and clearance, mirroring factory piston design. The hard-anodized ring landings prevent micro-welding, and accumulator grooves beneath the top and second ring lands reduce ring flutter and improve sealing.","brand":"Mahle Motorsport","offers":[{"title":"Default Title","offer_id":52662881386808,"sku":"MAH-PVN1","price":899.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/687501736.jpg?v=1784321740","url":"https:\/\/store.motormia.co\/products\/ie-spec-82-5mm-piston-set","provider":"MOTORMIA","version":"1.0","type":"link"}
