Description

Gain 10+ HP. Replace your restrictive factory charge motion control plates with Steeda's free-flowing plates and enjoy more power and torque. These high performance plates add horsepower and torque in the mid to upper RPM ranges without sacrificing low end torque for the kind of tire-frying power you can feel. Peak gains of up to 10 horsepower have been seen on naturally aspirated Mustangs, and more power is possible from supercharged engines.



Designed to Perform. As used on Steeda's Q335 Mustang, these plates are 0.070 thicker than the factory plates and are a better port match to the intake manifold and cylinder heads than your OE plates to untap hidden horsepower. They also delete the factory butterfly flow control to reduce turbulence and increase airflow - and as everyone knows, more airflow equals more power.



Billet Aluminum. These premium quality plates are CNC machined for precision out of aircraft-quality 6061-T6 billet aluminum so they won't weigh you down.



Application. The Steeda Billet Motion Control Charge Plates are designed for the 2005 to 2008 Mustang GT and 2008 Bullitt with the 4.6L three valve V8 engine. These plates will require computer recalibration - we recommend a Mustang Handheld Tuner to reprogram the vehicles computer (ECU) for proper operation. .

Note: As of the 2009 model year, Ford now molds the charge motion plates into the stock intake manifold. So they are not changeable.

Technical Notes. Will not work with 2009+ Mustangs.

This is an absolutely necessary step. The restriction is removed! You should see the stock butterfly valve assembly with actuator motor... GOODBYE! These really made a difference. Of course, I had Bama

Very Happy!!

After recieving my plates I coundn't wait to install them. It only took about an hour and the results were more then I had hoped for. These plates and American Muscle are number 1 to me!

Will this throw an engine code? I'm wondering if it will make my engine light come on and also will it work with the ford racing manifold or does that manifold have it molded in?

  • the frpp intake does the same thing as this and you will see almost the same power increase. the frpp intake has a little more power over 5500 rpm, but not much. this part will save you alot of money and you wont be disappointed with your increase in power. i would only buy the frpp intake because it looks good and people love it at car shows. but to answer your question, you dont need these with your frpp intake, it does the same thing.

  • You do not need it with that intake. They do the same job; intake will net you a few more hp but will cost you much more. Unless you are boosting or just like the looks, I'd go for the cmcp. Just makes hp:$ sense.

  • The Ford Racing High Performance Intake Manifold already deletes the charge motion plates so this product is unnecessary.

    A Must-Have!

    This is an absolutely necessary step. The restriction is removed! You should see the stock butterfly valve assembly with actuator motor... GOODBYE! These really made a difference. Of course, I had Bama tunes send me a new tune and loaded it while my mechanic was putting these on. The results were pure rock and roll. These are as important as CAI, TB, headers, and exhaust no doubt. Free airflow is key! Highly Recommended.

    Noticable gain

    February 25, 2012

    I keep seeing a bunch of post of "omg it really made my stang come to life!" to be honest with 4.10's and other bolt ons its hard to see that much of a difference. the install was easy peezy, the throttle response i will say is alot better. get this product if you're interested.

    Good upgrade

    May 20, 2011

    Nice upgrade, very easy install. Took about 1 hour to install. I noticed it pulls harder in the midrange. No waiting for the butterflies to open up. Smoother pull. My car is auto.

    The directions are straight forward. You can take off the fuel rail and injectors as one unit without disconnecting the main fuel line (so you don't need the special tool). The power gains are slight, but the real benefit is that power is instant... there's no more of that 1 second delay waiting for baffles to open up. Now I can just floor it and go.

    Took about 1 hour to install. Got to see the need for the oil separator while installing this... all that oil going back into the engine... does not look too great. Very easy install for the plates! :)

    Love it

    May 25, 2011

    This the 3rd mod I have done to the car. At first I was worried about installing this myself but trust me it was so easy. There was nothing hard about this at all. I also had a Baka tune to go with this. From first to 5th I could deff. Tell the car pulled harder and all around breathed better. Again do not worry about doing this yourself

    This upgrade really made my pony jump. I have the custom tune, with a gms TB, a magnapack catback, CAI, and now these! 1st gear.. you lose traction very easily now. The higher RPMS, the acceleration is amazing. This is a must have if you're looking for the next step.

    Easy install, decent gains, tune required!

    January 19, 2013

    These are made out of solid billet aluminum and add an extra 20 grams over the standard cast pieces with the butterfly valves and linkages. They are designed to fit 2005-2008 Mustang GT with the 4.6L 3V V8 engine. 2009-2010 Mustang GT intakes have the valves built into the intake manifold and will require a different product (delete plugs). A new engine tune/calibration is required because the IMRC/CMCV has to be shut off, and a few other things need to be done to maximize the power gains with these plates. After doing extensive research on these plates, I have found that with a good tune the plates alone will net approximately 10 rwhp gains without any loss of low-end torque/power. There are a lot of discussions going on about the potential for losing low end power, but based on discussions with tuners that I know and reading dyno graphs, the power gains are only positive throughout the engine operating range. The CMCV/IMRC is apparently used only for emissions control, as the new 5.0L DOHC V8 used in the 2011-up Mustang GT does not use any type of IMRC/CMCV and instead has variable cam timing for intake and exhaust valves that most likely do all of the emissions reduction. The overall installation took about 3-4 hours, mainly because I took it very slowly and had numerous meal and bathroom breaks. My 07 Mustang GT also had about 12k miles, so the intake manifold gaskets (the green silicone/Viton gaskets attached to the valve plates) got really stuck to the cylinder heads and required some additional force to lift out. There was also a lot of dirt and grit to clean out of the engine due. The LH plate is for the driver’s side, and the RH plate is for the passenger side. I followed TacoBill’s installation guide, which has the best photographs of any online guide I have found. The fuel line does not have to be disconnected, and the air intake tube does not have to be removed either. The air intake tube at the throttle body has to be disconnected though. Also, the vacuum tube on top of the PCV tube simply requires the white tab to be fully depressed to disengage the lock (the tube above the one with green rotating lock tabs). After installing the plates and my new tune, I did not see any check engine lights or RPM flare up after a cold start. It started up like normal and idled very smoothly. I have not taken it on the road for a test because of the weather (winter in Michigan) but it did not exhibit any problems. Overall: 5 out of 5 stars, a great modification if you wish to stay naturally aspirated or utilize the stock intake manifold. I originally wanted to buy the Ford Racing intake manifold, but every dyno test of that intake showed significant decrease in power and torque below 5000 RPM with all of the gains well above 5000 RPM. Even with the 3 Stage CNC heads and Hot Rod cams, the Ford Racing intake manifold only showed gains at the 6000-7000 RPM range, and the stock intake manifold provided the largest area under the power and torque curves in all of the scenarios.
