Designed by ZRP engineers and manufactured in Germany from high-silicon, low-expansion 4032 (T6) alloy. This allows the engine builder to use a smaller piston-to-bore clearance, which results in a better seal. This minimizes cold start knocking noise, common in engines using forged pistons, providing quiet operation and low oil consumption. We have chosen a full-round skirt design with lower reinforcement band, with oversized and deeper valve pockets to allow for the use of high-lift camshaft profiles. They have offset pins for quiet operation and the piston pins are made from 9310 alloy. Other features include anti-detonation grooves to protect the top rings, gas pressure accumulator groove for improved ring sealing, and vibration relief. Premium Japanese quality 1.00mm x 1.20mm x 2.80mm ring pack included. Product Features and Design Anti-detonation grooves for increased durability and performance Gas pressure accumulator groove in the second ring land for increased durability. Horizontal grooves in the pin bore designed to allow oil to enter between the piston pin and the pin bore area. CNC precision machined ring grooves High silicon\/low expansion 4032-T6 alloy Polished pin bores Full round skirt design with lower reinforcement band for high horsepower\/supercharged applications Valve pockets designed to allow for oversized valves and high lift camshafts Pistons designed to optimize compression for increased engine life and increased power potential Optional coatings offered upon request \"Blast Off Bronze\" thermal barrier coating Molybdenum side skirt and undercrown \"Stealth Black\" coating\u003c\/p\u003e","brand":"ZRP","offers":[{"title":"Default Title","offer_id":56965458886996,"sku":"ZRP-43501-740","price":957.57,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1027\/4701\/3460\/files\/43501-740_44243d2a-d89a-4991-860f-d03ed551dc8c.png?v=1788682415","url":"https:\/\/www.thetunerlab.com\/en\/products\/pistones-forjados-zrp-para-toyota-1-3l-starlet-4efte-74-00mm-8-3-1","provider":"Thetunerlab","version":"1.0","type":"link"}
