Features & Details

  • Gain 10+ HP
  • Improves Torque
  • More Midrange & Upper Rpm Power
  • CNC Machined Billet Aluminum
  • Installs Using Hand Tools
  • Fits 05-08 Mustang GT and 08 Bullitt
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: Coupon codes cannot be applied to this product.

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

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.

  • The Steeda Billet Charge Motion Control Plates do not need any other things done while the intake is off. please keep in mind, a new tune will be required when deleting the charge motion control valves with this component.

    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.

    Easy install, decent gains, tune required!

    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.

    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

    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.

    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.

    Free air

    These are very high quality for the buck. Get rid of the motion control valves and get even more power. I installed myself with standard tools. It took me around 6 hours and I really took my time with it. The directions are not that great so make sure you know the car or have a shop manual handy to make sure you get everything detached before you pull the intake off. It's hard to say how much power this adds but it can't hurt. With long tubes, CAI, underdrives, under drive pulleys, 93 Bama tune, GT500 TB and got 347 RWHP on they dyno.

    The part quality is excellent. Install time was around 90 mins with only a few tools. The car had a feeling of accelerating easier and faster with less gas pedal. This were installed after my long tubes and mid pipe along with a bama tune. Totally worth it.

    Best modification yet!

    First thing you notice is it is a shame that these are hidden. They are a beautiful piece of machine work! Installation is straight forward but don't forget to disconnect the vacum line for the brake booster. No other surprises. I completely removed the actuator motor since my Bama tune deleted it. 5 pounds of dead weight gone! Throttle response is much quicker both on and off. Bottom line.....do it!

    air flow

    Well these helped greatly and are a must with a turbo application. I only got 481 and 500 trq before these and after I got 687 rwhp and 760 tq. Now I know on a stock motor the gains aren't that big but on my turbo setup the stock control valves weren't opening correctly and not letting boost in. So best money spent for me. And they look way better than stock.

    I got these installed with the Under-drive pullies, Ford hot rod cams and a tune and what a difference!! I laid down 332hp and 322 tq. This car is a whole new beast and i can tell the car adapted to the plates with the amount of high end pull it gives, it just screams to 6500 RPM and i can tell the open valves have helped. Thanks American Muscle for all the parts and fast service.

    Easy Install

    These things were a breeze to install. Instructions were clear and came with pictures. I had a new tune ready from Bama, took the car out for a spin and you can really feel a change in 1st and 2nd gear. Two things to been on the look out for: #1 - Ensure the area around the stock CMCP/ Intake manifold are clear of any dirt/debris. With the intake off, it is a straight shot into the engine. #2 Be CAREFUL when pulling off the fuel rails. Some folks said they came off easy; others said it took everything they had to get them off. My drivers side came off fine. Passenger side was a little stubborn. One end popped out and the other end stayed stuck. End result, I ended bending an injector port on the fuel rail. Overall I am extremely pleased with this product. Fast shipping by AM and great product by Steeda.

    Delete Plates rth the tment

    Installed the delete plates in about 2 hours. Very easy install with easy to follow instructions. The old charge motion plates were soaked with oil. After install I downloaded my 91 street tune. The change is noticeable throughout the RPM range, I did not notice any loss of torque and the car pulls hard. I agree with others reviews, it is like loosing an anchor. Worth the investment.

    I would say it is worth it.

    It is hard for me to say how much you actually gain from these. I have added a cold air intake, throttle body, tune, exhaust, headers, under drive pulleys, etc..... in the last month.... Worth it to eliminate the oil covered valves that do obstruct flow .... I would recommend them and guess at 10 or less HP gained, I was looking more for long term when I add a supercharger.

    Ordered these to complement my cams and headers. Went with this as an alternative to the FRPP 3V intake and happy with my decision. Quality is top notch so worth the price. Only would recommend if you have cams or headers as it will not help much otherwise.
