would this battery fit 03 roush stage 2? whats better the optima red or the yellow one?


  • Unfortunately, the Optima website does not indicate that they produce a battery specifically for the Mustang. That being said, I seriously doubt they would advertise it unless they were sure. It will fit your Roush Mustang. Yellow top is designed for cars running a high electrical load, such as serious stereo equipment. They red top is for the average street rod, SUV, trucks, and high compression motors by providing a strong initial burst to get things rolling. Unless you added a lot of electronics, the red top is good for your car.

Does the Optima Red Top Battery fit under the hood of a 2004 Ford Mustang V6? I went to Pep Boys and they told me that the Optima Red Top Battery doesn't fit in the V6 Mustang 3.8 L due to interference with the hood top.

    Excellent Battery

    This Optima Red-top battery replaced my old Duralast battery, with an unknown amount of miles on it. My car now starts up quicker, and does everything a battery should. All my accessories seem to run brighter too. When installing, be sure to use the two wing adapters, they are necessary to properly mount the battery,

    Best Battery, Period

    I'm on my 3rd Ford, and 3rd Red Top battery, and have been overly satisfied with each and every one. From the Probe Gt, to the Mustang Cobras, they were a great upgrade from the run-of-the-mill Autozone battery. They fit great inside of Taylor's trunk relocation box as well (old style battery did not! was too big!). For the looks, performance and price, you can't go wrong.

    Great performance, but......

    Stellar electrical performance, simply awesome. But the battery is too large for the stock tray. Why AM or any other retailer sells this for a 96 Mustang is beyond me. I was able to overcome the space limitation by taking a dremel and literally melt a notch into the lip of the tray closest to the fuse panel. It's the pink bit and 9000 RPM seems to be a good speed to cut your way through. Use the V-shaped hold down supplied from Optima and hopefully your stock hold down bolt isn't rusted. There are retailers out there which supply this bolt as well.

    Great battery

    I ve had 2 Optima redtops in 10 years switched out between at least 8 cars. This battery is a performance monster, only slight issue, yes the battery is a bit large for the battery tray, AM is not to blame, Optima is used in a wide variety of vehicles, this battery is not Mustang specific. Solution is either swap your battery tray for a larger one ie a F150 truck tray, or simply pull your tray out and cut the side of it out for the battery to fit. All in all, this battery has not failed me, I left my lights at work for 8 hours and this baby started right up.

    StangBang for your Buck

    Great battery! i just swapped my old motorcraft stock battery for this optima, and theres a big difference in overall power and the way my sound system works. The car starts easily, no dry sputter or choking on start up. And can you say fast shipping?? should change their "standard shipping" to "open your front door as soon as you enter your credit card number." Thanks AmericanMuscle!

    Red Top to the Rescue

    I relocated my battery to the trunk to make room for a double oil filter setup. My battery was not starting well when it got warm. That's when I chose a Optima Red Top. A sealed battery in the trunk is a good deal, and also with a sealed battery box made it even better. Very easy install. And it looks cool as well. No problems starting now.

    Would be a five start except it was just a little too big for my 2K stang. It pushes the edges of the battery holder out. I expected perfect fit from Mustang speciality site.

    2007 Mustang GT

    This battery installed in 15 minutes. The cranking power is awesome to say the least. Recently in Wisconsin we had a number of days of sub-zero weather. The car sat for 3 days in -20 degree (wind chills to -35 -40) weather. The car started with a single crank. I would recommend this battery to any one for any application. It was a well spent 200 bucks. Delivery was very prompt and there were no issues regarding fit.
