Review on AEM 21 422C Metal Intake System by Arturo Reyes

Installing the air intake took about 2 hours, the hardest part was removing the old system. To do this, you need to remove the driver's headlight and unscrew the screws in the wheelhouse (not necessary, but easier). Keep a 2000-2003 Haynes Haynes Dodge Neon (Haynes Manuals) or a 2000-2003 Chiltons Dodge Neon (Chilton's Total Car Repair and Maintenance Manual) as removing some of these parts can be confusing at first. After installing the new system, the machine would not idle, and after much fiddling I got it running. for a while while the system is transitioned to the new intake. I didn't like the vent hose that came with it, it was just too short. I went to the auto zone, bought 3 feet of 1 inch radiator hose, cut it off and used that instead. Take a look at the AEM website ([.] ). There you will find "21-422 2000 Dodge Neon SOHC CAS.pdf" which contains AEM statistics on expected performance gains. The greatest increase was at 4500 rpm: 6.6 hp. and 7.7 feet. -lb Don't expect your neon to be a race car once installed, even if the air intake sounds like it. One issue I couldn't diagnose was a loud hum the car makes at times while idling. I don't know if this is a problem with my installation or something else. If you live in an area with bad weather, this can help. Inlet bypass valve AEM 20-401S
