## Overview

The GM Performance 12496821 Intake Manifold is a high-quality aluminum intake designed specifically for throttle-body fuel injection systems on pre-1996 Vortec engines. Compatible with all Vortec cylinder heads, it features an EGR-ready design and requires specific coolant bypass routing on newer engines. Manufactured in the USA, this intake manifold delivers durable, lightweight performance tailored for serious enthusiasts seeking reliable power upgrades.

## Description

Designed for throttle-body fuel injection Aluminum intake will work with all Vortec cylinder heads, including P/N 12558060, P/N 19300956, P/N 19300955, P/N 25534421, or P/N 25534446 Also accepts EGR NOTE: The exhaust manifold from 1996-and-newer pickup trucks with RPO L31 350 engine, P/N 12557828, is drilled and tapped to accept an EGR tube. EGR pipe P/N 10220275 can be used with EGR Valve P/N 19210662 and gasket P/N 12337972. This manifold is primarily intended for use with Vortec heads on pre-1996 engine blocks. Blocks manufactured in 1995 or earlier have thermostat byp page from the block directly to the water pump. If manifold is used on 1996 and later engines (which do not have the byp in the block), you must run a coolant byp line from the manifold to the 5/8” hose nipple on the water pump (penger’s side). Suggested routing is from the 3/8 NPSF boss on manifold to the water pump
