{"product_id":"piston-and-cylinder-kit","title":"Piston and Cylinder Kit","description":"Upon installation, users can expect a notable increase of 5% in Horsepower and Torque, even when running stock engine mapping. This upgrade is not merely a simple component swap; each piston (11.66mm) and cylinder in the Autotech HPFP kit undergoes multiple high-precision grinding processes. This meticulous manufacturing ensures the most precise tolerances are maintained throughout the production, resulting in exceptional accuracy and longevity. Furthermore, each piston and cylinder are match-ground and serialized, guaranteeing absolute precision. Autotech pioneered the use of plasma DLC coating on HPFP components to minimize friction losses and enhance performance, a feature that sets their kits apart.\n\nThe HPFP is a critical element in GDI engines, responsible for boosting fuel pressure to extremely high levels (often exceeding 2,000 psi) for direct injection into the combustion chamber. This direct injection leads to better fuel atomization, improved efficiency, and increased power output. Over time, wear, contamination, or internal failures can lead to various drivability issues, including hard starting, hesitation, misfires, loss of power, check engine lights, and reduced fuel economy. This Autotech upgrade serves as a direct replacement for failing pumps and offers enhanced performance capabilities.","brand":"AutoTech","offers":[{"title":"Default Title","offer_id":52687034581304,"sku":"10-127-203K","price":295.96,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/661169078.jpg?v=1784879755","url":"https:\/\/store.motormia.co\/products\/piston-and-cylinder-kit","provider":"MOTORMIA","version":"1.0","type":"link"}
