Designed by ZRP engineers and manufactured in Germany from 4032 (T6) high-silicon, low-expansion alloy. This allows the engine builder to run a closer piston to bore clearance thus producing a better seal. This minimizes the slapping noise during cold start, common place among engines running forged pistons, providing a quite operation and low oil consumption.We have chosen a Full round skirt design with bottom reinforcing band, with oversize and deeper valve pockets to allow high lift camshaft profiles to be used. They have Offset pins for quiet operation and the wrist pins are made from 9310 alloy. Other features include Anti-detonation grooves to protect the first rings, gas pressure accumulator groove for better ring seal and vibration relieve. Premium Japanese quality 1.00mm x 1.20mm x 2.80mm ring package included.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003e\u003cu\u003eProduct Features and Design\u003c\/u\u003e\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eAnti-detonation grooves for long wear life and performance\u003c\/li\u003e\n\u003cli\u003eGas pressure accumulator groove in the 2nd ring land for longer wear life.\u003c\/li\u003e\n\u003cli\u003eHorizontal slots in the pin bore designed to allow oil to enter between the wrist-pin and pin-bore area.\u003c\/li\u003e\n\u003cli\u003ePrecision CNC machined ring grooves\u003c\/li\u003e\n\u003cli\u003e4032-T6 high-silicon \/ low-expansion alloy\u003c\/li\u003e\n\u003cli\u003eHoned pin bores\u003c\/li\u003e\n\u003cli\u003eClip cuts on the edge of the Intake side\u003c\/li\u003e\n\u003cli\u003eFull Round skirt design with bottom reinforcing band for High HP\/Boost applications\u003c\/li\u003e\n\u003cli\u003eValve Pockets designed to allow over size valves and high lift camshafts\u003c\/li\u003e\n\u003cli\u003ePistons designed to optimize squish for longer engine life and increased horsepower potential\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003e\u003cu\u003eOptional coatings offered per request\u003c\/u\u003e\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eThermal barrier coating “Blast Off Bronze\"\u003c\/li\u003e\n\u003cli\u003eMoly Side-Skirt and Under-Crown coating “Stealth Black”\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ZRP","offers":[{"title":"Default Title","offer_id":53493614707030,"sku":"ZRP-41104-875","price":1179.51,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0935\/6119\/2790\/files\/41104-875-c.jpg?v=1778096535","url":"https:\/\/driftmafia.life\/products\/forged-pistons-zrp-for-bmw-3-2l-m3-s54-e46-87-50mm-9-0-1","provider":"DriftMafia","version":"1.0","type":"link"}
