I am satisfied with this product but 2003 to 2004 cobras are known for having issues with their alternators. It is covered on a few forums that this alternator along with the metco over sized alternator pulley is necessary to prevent damage and preventing a short life. LMR was the lowest price for this product to include shipping. I searched for days. Fitment is perfect and your old pulley or the metco is needed to complete the install. Just take an impact gun with socket to get your pulley off the old alternator. If your battery light comes on and off at low rpms you need this. You can confirm this by taking your car to a local autozone or part store that will check your charging system for free. I also got this alternator so I can utilize the PA repair kit to rebuild the alt if necessary in the future which will save you 200 instead of replacing the whole alternator. This repair is a must if you start noticing your voltage dropping especially if your Cobra is modified. Irregularities in voltage can cause issues in tuning and is sometimes overlooked in tuning. It is a good idea if you increased boost to also monitor voltage. I also got the ford racing autometer voltage gauge just for that.
