We have a few left of these from our last production run. It will probably be another 1.5 years before we do another run so if you want to get one, dont delay!

We are proud to present our Aluminum Rear Diffuser for the 03-05 Neon SRT-4! A sharp looking piece that keeps air from being caught underneath the car at high speeds and helps it exit without too much disruption.

DESIGN
The MPx diffuser is designed to push air away from the rear bumper and carriage to reduce drag and turbulence caused by the rear valance, exhaust and suspension hardware. It also utilizes fins to stabilize the moving air moving past the diffuser.

CONSTRUCTION
There are a total of two large main panels that connect via a connecting plate on the top and one of the main fins in the middle. Every panel are made from aluminum and all pieces are nearly 4mm (or 1/6 inch)thick! (This photo shows that its the thickness of 2 pennies stacked)



This is not just some flimsy sheet metal! All solidly cut, and made in the USA on a plasma cutting machine.

INSTALLATION
Installation secures the panels to nearly 20 points around the bumper and sub-frame. Once installed, the diffuser is extremely solid and good looking. In order to install you'll need to drill holes on the bottom corner of the bumper (once removed it cant be seen unless your under the car!) and four main bolts in the carriage on the bottom of the car.

For those of you that have a side exit exhaust or dump beneath the car, you can get our sold seperately rear diffuser block off kit. This kit includes two aluminum panels that block off the exhaust ports for a nice clean solid looking diffuser. Search for part number 220750-BLOCKOFF in our search bar to see that kit and be sure to add that item, and the diffuser to get both if you want a block off diffuser package.

FITMENT
This diffuser is currently designed to fit with the stock exhaust, Mopar performance exhaust, MPx exhaust. It will NOT fit with the Thermal exhaust. We cannot guarantee fitment at this time with the B&B exhaust, Injen exhaust or other exhausts. Contact us if you have the B&B, or Injen exhaust or any other exhaust to discuss.

We include templates to drill, photograph installation instructions, all stainless steel bolts with nylon lock nuts and 4 self tapping screws.

Note: because this piece has a raw finish, and its not polished, scratches can occur during the manufacturing process. Each piece is hand inspected and we do not allow diffuser fins and panels to pass that are really blemished though.

Furthermore, the diffuser will need to be cleaned after installation to remove fine scuffs and finger prints. We highly recommend using Brasso metal polish to maintain a nice luster and remove finger prints, etc.
