Exhaust Manifold 1714121090 for Toyota 2NZ-FE Engine
The exhaust manifold (Part No. 17141-21090) is designed specifically for the Toyota 2NZ-FE engine. The component itself does not possess independent physical performance parameters (such as flow rate or pressure resistance); its key specification is that it is a genuine part matching original equipment manufacturer (OEM) standards. It is typically constructed from cast iron or stainless steel and features a four-cylinder, single-outlet flange connection design.
