MPx 62mm Throttle Body & Spacer, 03-05 Neon SRT-4

Model Number: 220127-
Do you want a simple bolt on piece that will SIGNIFICANTLY improve your throttle response, and give your 03-05 SRT4 another 8-10 horsepower? If so, read further!

This throttle body makes more power, and improves acceleration because of the larger throttle plate and throttle bore that allows more air to pass than the factory throttle body.
The size of the factory throttle body is 55mm and it necks down to 52mm, whereas the MPx throttle body has a 62mm bore.

The MPX throttle body and spacer was made from scratch out of CNC machined aluminum, and is anodized with a special hardcoat for resistance to corrosion and oxidation.

Your stock sensors will attach onto the throttle body, and the throttle body and spacer piece mount directly to your intake manifold.
Theres NO cutting, or modification to your intake manifold, or air intake system needed. We also provide installation isntructions to help you install this onto your car.

Unit comes complete with gasket to be used in between the spacer and the throttle body, as well as bolts to attach it to the intake manifold.

Please note: if you have a stock pcm tune, we recommend you not install this. This throttle body works best with aftermarket tunes such as the Mopar stage 1, stage 2, stage 3, Diablosport tunes, and other tunes, basically ANYTHING except the stock pcm flash. This is because the stock pcm flash is not designed for a larger throttle body and can therefore have a hanging idle when decelerating. Your car will still run and idle fine if you install this with a stock pcm flash but could have a high idle when coasting to stop lights, etc.

      No, these are quite a bit different, and they are not interchangeable with the 00-05 Neon.

    Hello, was just wondering if the mpx 62mm throttle body will work on the 2005 pt cruiser turbo?
    1 Answer
    • customer service rep

      No, this will not work on a PT Cruiser for the following reasons:
      1) The PT throttle cam rotates counter clockwise, this throttle body rotates clockwise
      2) This has a spacer, the PT does not

      The MPx throttle body works very well with the Diablosport tune! No custom tune needed.

    Is this throttle body 62mm completely?
    1 Answer
    • Customer Service Rep

      Its 62mm at the inlet, and 59mm at the outlet. It slightly tapers, because the inlet to the intake manifold is 59mm inlet size.

    Would the stock charge pipe fit hose into this throttle body fine?

      Its a very tight fit with the factory uppipe, its really best to use the AGP uppipe with this throttle body because it has silicone couplers which are more pliable than the factory rubber piping.

    Will you guys sell the spacer only?
    1 Answer
    • Customer Service Rep

      As of 11/29/2016, we do not sell the spacer separately. This is because when we make this throttle body we make them in equal batches of throttle bodies and spacers and do not have spares.

    Is this kit complete, or do I need to purchase any other gaskets? Also, will this work fine with an aftermarket ecu flash like the Syked tune?. I also have the JMB upper/lower hard pipes and mopar cai.

      There are two gaskets needed to install this, and both are included. The throttle body to spacer gasket, and the spacer o ring. So, nothing else is needed on your part.

      This will work fantastic with the Syked tune and all other pcm flashes like the Mopar staged tunes, Diablosport, SCT, etc. It will work with a stock pcm, but its best to use this with aftermarket performance pcm flashes like mentioned above.

      Because the throttle body has a larger outer diameter, its best to use this with an aftermarket upper pressure pipe with silicone coupler. Silicone couplers can expand better than the rigid factory rubber piping and its extremely difficult to put this on with the oem rubber pressure pipe.

    If I remove the throttle body will I have to replay both gaskets everytime I remove it ?

      The rubber o ring on the manifold can generally be reused multiple times. The paper gasket between the spacer and the throttle body generally cannot be reused and should be replaced.
