Show original supplier description
The KS Tuned Gen 2 Spray Plate is a performance enhancement component designed for engines utilizing a 90mm Mustang flange pattern, commonly found on aftermarket intake manifolds such as the Skunk2 Ultra and other sheet metal intakes. This upgraded Gen 2 version replaces traditional gaskets with o-rings for improved sealing and reliability. Constructed from durable billet aluminum with a black anodized finish, the plate features five internal injection ports. It is equipped with four stainless steel fittings that accept standard nitrous jets, allowing for flexible configurations. Users can run dual-stage wet nitrous shots or up to four stages of dry nitrous. Additionally, the plate accepts up to two methanol attachments (sold separately) for the use of pure methanol or water/methanol mixtures, compatible with most meth controllers. KS Tuned has tested each fitting for up to 200 HP. The plate includes necessary bolts and o-rings for installation. The product page also provides a detailed chart for selecting nitrous and fuel jet sizes based on target horsepower, ranging from 55 HP to 100 HP, though it notes that jet size is dependent on both fuel and bottle pressure.
