Review & Install Video

Hi everyone I’m Justin with AmericanMuscle.com and I’m taking a look at a great way to add some show winning style to your engine bay, thanks to these fuel rail covers for your 05-2010 Mustang GT. The covers themselves are made from a durable heat resistant composite material and are finished in a titanium silver, which flows extremely well with your stock intake manifold cover. Not only that it hides the unsightly fuel rails, wiring and clutter, making for a much cleaner bay. Installing the covers should take you about 30 minutes per side making for a total install time of an hour or so give or take using the supplied allen wrench and detailed instructions. Now if you’re one of those people who like to save the hardest part until last, do yourself a favor and start with the passenger side, because the driver’s side gets a little tricky. If you’re digging the look these fuel rail covers are giving your engine bay but you’re still craving a little more, then you might want to check out our matching fuse box cover, or plenum extension throttle body cover to complete the look. There’s nothing worse than having an awesome looking ride, only to pop the hood to reveal a cluttered mess of wiring and hoses, so if you want to dramatically clean up your engine bay, you’ll definitely want to check out these fuel rail covers for your GT.

Money Saving Kit. If you're ready to add some serious style to your 2005-2010 Mustang GT's engine bay, our money-saving SpeedForm kit contains everything you need to dress up your engine bay for show-winning good looks.

Race Ready Styling. The SpeedForm Engine Cover included in this kit includes the famous "running pony" emblem with "Powered by Ford" lettering - so everyone who looks under your hood knows what keeps your pony leading the herd. And with the matching finned fuel rail covers and throttle body extension, this kit gives your engine bay a race ready look that will appeal to any Mustang fan.

Premium Materials. All the pieces of this SpeedForm kit are made from heat resistant composite that is light, durable, and won't slow you down. This composite also matches the factory accents.

Fitment. This SpeedForm kit fits 2005-2010 Mustang GTs (does not fit GT500).

Technical Note. The 2005-2006 GT Mustangs will require the 2007 GT Ford Factory Throttle Body Studs - part# W712289S437, and the Ford Factory Nuts - part# W520411S437 for proper installation.

      I see the description you have mentions "SpeedForm Intake Plenum and Fuel Rail Covers". However, it does not mention the throttle body extension cover. You do show a picture of the throttle body extension but is it included in this kit as well?

      Will this item work on my 2008 Bullitt? It has the Ford Racing Intake and the factory strut bar. Thanks.

      • The SpeedForm Intake Plenum and Fuel Rail Cover kit is designed to fit the stock intake manifold, and will not fit on the Ford Performance Intake Manifold. This does fit under the Bullitt strut brace.

          kit and installation

          Packaged well, look good, Pictures on directions are very small and hard to see and kit should include new bolts to go in the front of plenum. I had to drill out spacers sleeves to get bolts threw and trying to get nose piece on was impossible till I got longer bolts. I also had to lengthen a hose that went over the side rail, on the drivers side,as its higher that what the factory allows for by about and inch

          Easy install

          These are great! They look very clean and are quite easy to install. If you have a modified throttle body spacer or CAI you might have to make some adjustments like I had to. I had to remove my spacer on my 62mm throttle body to make room for the intake plenum but I think that the sacrifice is well work the look you receive.

          Intake Plenum and Fuel cover on 07 GT/CS

          Although it is not made in other colors then Silver on Gray, I repainted mine to Blue on Black which looks better on my car. Given the steep price for this, it would be nice if other colors were an option. Also during installation one of the fuel rail mount Riv-nuts fell off the mount. I was able to replace it with one from the hardware store and my fathers hand held rivet driver. The mounting system needs to be engineered better to account for the engine wiring harness and fuel supply tubes on both sides of the engine. Overall I am happy with the appearance of the Speedform Intake Plenum and the Fuel Rail covers, after some modifications, I just wish the mounting system was better.

          Plastic?

          In short, the entire set looks and feels like plastic. Not bad looking but it's not me. So I took the set around to various paint shops to pep the look up but as I showed them what I was trying to powder coat with paint, they were all amaze that the entire set was made out of plastic. I thought, they were correct and for the money I paid it didn't seem worth it. Thus, I sent the entire set back for refund. I paid almost $50.00 just to return the item at my expense.

          intake plenum and fuel rail covers

          Was hesitant to pay this much for plastic covers but they are very thick and good quality. I painted these same color as car and they look fantastic. No regrets. they fit perfect and install only took about an hour.

          SpeedForm Intake Plenum and Fuel Rail Covers

          fits like a glove. cleans up the engine bay a lot. directions need to be a little more clear a step or 2 needs to be added to make it better. Must be very careful on the install not to mar , chip or scratch them that happens to easy with them parts. the Throttle body cover install need directions especially if your car does not come with one need a set of nuts added to the install kit.

          They look great; Install, so-so

          These look great once they are installed in the engine compartment, but... Installation is a little tricky due to the fact that they are a generic fit for 05-10 GTs, which are not at all generic. The kit is also a bit pricey for molded plastic that scratches easily while installing it. Time for installation, once you have all the correct screws and a deep-well 5/32 socket, is less than an hour, not too bad, but for the price, all the screws should be with the kit ready to go so you don't have to go hunting for them (three stores, not everyone carries the recommended size or the replacement intake machine screws. The wiring bundles differ, the hose locations are slightly off, so you have to moderately modify them to accommodate these things to make them fit correctly. The stock bolts for the intake are just about 5/32 short, so you need longer bolts to install the intake and plenum covers properly. The side fuel rail covers have the mounting screws fairly far back, which is cumbersome to get to with the battery and master cylinder hampering the area. Also, the recommended screw length was a tad bit short to get a starting bite into the metal, two trips to the hardware store. Other than that, these are a great addition to your engine bay and will enhance the overall finished look that Ford should have done to begin with.
