Wiseco Nissan QR25DE Sentra 2.5L 16V 89.00mm Bore Standard Size -19.5 Dome Dish 8.4 CR Piston Set

This is a set of four forged pistons from Wiseco, specifically made for Nissan QR25DE engines. You get the pistons themselves, which are designed to replace your stock ones and handle more demanding use. These pistons feature an 89.00mm bore, a standard size for this engine, with a -19.5cc dome dish that contributes to a compression ratio of 8.4:1. They also include precision ring grooves, anti-detonation grooves, and features to improve ring seal, all aimed at boosting performance and durability.

Wiseco builds these pistons from 2618 aluminum, a material chosen for its improved tensile strength, making them well-suited for heavy or severe duty performance builds. The crown of each piston is fully machined, and they come with forced pin oiling to ensure proper lubrication. Additionally, these pistons have an ArmorGlide skirt coating, which helps reduce friction, resist seizure, and operate more quietly. This set is designed and built in the USA.

Keep in mind that these pistons are not CARB approved and cannot be shipped to California. If you're rebuilding the top end of your QR25DE engine for serious racing or heavy performance use, these Wiseco pistons are a solid option to consider for improved strength and reliability.
