NGK 3783 BKR6ES Spark Plug

The Fiat 1.4L T-Jet pistons are developed for moderate to high-level tuning, primarily for street or club racing cars looking to build their engine for high mileage and/or street use. Designed by ZRP engineers and manufactured in Germany from high-silicon, low-expansion 4032 (T6) alloy. This allows the engine builder to use tighter piston-to-wall clearances, resulting in better sealing. This minimizes cold-start piston slap, which is common in engines using forged pistons, providing quiet operation and low oil consumption. We have chosen a full-round skirt design with a bottom stiffening band, featuring 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, a gas pressure accumulator groove for better ring sealing, and vibration relief. Premium Japanese-quality 1.00mm x 1.20mm x 2.80mm ring package included. Product features and design Anti-detonation grooves for increased durability and performance Gas pressure accumulator groove on the second ring land for increased durability. Horizontal grooves in the pin bore designed to allow oil between the piston pin and the pin bore area. CNC-machined ring grooves High-silicon/low-expansion 4032-T6 alloy Honed pin bores Clip cutouts on the intake side edge Full-round skirt design with bottom stiffening band for high HP/Boost applications Valve pockets designed to accommodate oversized valves and high-lift camshafts Pistons designed to optimize compression for increased engine longevity and higher horsepower potential Optional coatings offered upon request "Blast Off Bronze" thermal barrier coating "Stealth Black" molybdenum side skirt and under-crown coating
