NEW version Greddy recently released intake manifold for S13 SR20DET. The injector ports have been edited with tabs allowing the Greddy fuel rail to work with the S13 Manifolds.
The casting is high quality and nothing comparable to those cheap ebay manifolds. All the fittings, hoses, and fuel line adaptors are included with this.
Expected gains are around 15hp on a stock SR20. More HP gains with a larger turbo.
GReddy Intake Plenums are designed to maximize performance in highly tuned engines. The fine cast-aluminum intake manifolds allow for large volumes of air to get evenly distributed to the cylinders. To achieve the most form larger turbochargers at higher boost levels, a smooth flowing GReddy Intake manifold is a must.
