Overview

The JM Fabrications SRT4 intake manifold is a performance upgrade designed for the Dodge Neon SRT-4. It is constructed from 6061-T6 aircraft quality aluminum with a CNC machined billet runner section and velocity stacks. This manifold aims to increase horsepower while maintaining spool and streetability.

Features include CAD design, angled and tapered runners to match port entry, and an O-ringed head flange that eliminates the need for a gasket. It also includes a 5-port vacuum plate with 1/4" NPT threads and offers various finishes and throttle body flange options.
Show original supplier description
The JM Fabrications SRT4 intake manifold is engineered for Dodge Neon SRT-4 owners seeking enhanced performance. It boasts angled and tapered runners that precisely match the port entry, an O-ringed head flange for a leak-free seal (eliminating the need for a gasket), and a 5-port vacuum plate with 1/4" NPT threads for easy accessory hookups. Multiple finishes and throttle body flange options are available to suit various setups. The plenum dimensions are 16" long and 4 1/4" deep, featuring a 1" taper design to ensure even airflow distribution. Velocity stacks are incorporated to further boost airflow efficiency. JM Fabrications states that expected gains can range from 10-45 HP, depending on the vehicle's specific setup and tuning. A dyno test on a car with a 50-trim turbo kit, 2.5" exhaust and IC piping, upgraded FMIC, running 19psi on pump gas, showed a 24hp and 10ft/lb increase over the stock manifold. Installation may require modifications to the upper IC pipe, radiator hose, oil dipstick, and thermostat housing hose. Professional installation is highly recommended. The package includes the intake manifold, various brass hose barbs and fittings, stainless steel mounting hardware, fuel rail mounts and spacers, and a silicone replacement coolant hose.
