Show original supplier description
The Tomei TA303D-NS16A is a genuine replacement valve intended for servicing and maintaining your TOMEI performance engine setup. This part is specifically designed as a repair component, making it suitable for engine rebuilds, performance refreshes, or as a direct replacement for worn-out valves. This specific valve is designed for the KA24DE engine and is part of Tomei's racing valve line. Applications include Nissan 240SX models from 1989 to 1998, with specific fitments potentially including SE, Base, and LE trims. It is crucial to confirm compatibility with your exact vehicle application before purchase. The product is listed as new and is a single intake valve. While many sources indicate it is designed for the Nissan 240SX, the original listing notes 'No Fitment Data. This product doesn't have fitment application data. Please verify fitment manually.' Always ensure this part is the correct specification for your build, especially when dealing with performance engine components.
