I will begin my review by stating: I am your average Joe who likes to read automotive manuals, BMW blogs and watch BMW X5 do-it-yourself YouTube channels. I do 95% of the work on my 2003 BMW X5 4.4I. First and foremost I attest: I have no relationship to anyone at POWER BASTERS. I am not receiving any royalties, favors or free equipment from this company. I don't even know where they are located. I will attempt to relay to you my pain and the leap-of-faith I took in buying a high performance alternator from POWER BASTERS.

Anyone who owns a late model BMW X5 4.4I; in particular the do-it-yourself-er who understands the work the time involved in replacing a part below the the air filter on these X5's. For those relying on mechanics-the expense is mind-blowing. There are always issues like removing other parts directly blocking the part you want to replace. Then there is the need to purchase a variety of specific tool and/or a particular OBD2 scanner. I realized I couldn't trust big chain auto-parts store for parts without first doing the research to verify the exact part. Their data bases regarding BMW X5 part are for the most part lacking in relevant information. Like any other merchant. They just want to sell you a part and off you go. If its the wrong or it fails bring it back-easy for them to say!

AT ISSUE: The 160 amp water-cooled alternator in my 2003 BMW X5 has been replaced 5 times FROM 2012 TO 2020. When auto-parts store alternators began to fail me. I went to a machine shops specializing in rebuild alternators and starters. The re-builds after a longer interval failed as well. I had the electrical system checked twice-their diagnosis good battery, good wiring system but it had a bad alternator-tell me something I don't know already!

THE FIRST SIGN THE ALTERNATOR WAS GOING BAD WAS A PARASITIC LEAK I FOUND BY LUCK. I did numerous FLUKE METER parasitic leak testing-I couldn't find the power draw. The new battery was slowly losing its charge while parked. WHEN THE ENGINE WAS ON THE FLUKE METER INDICATED THE ALTERNATOR WAS CHARGING THE BATTERY. HOWEVER THE BATTERY GAUGE LIGHT OFTEN TURNED ON. Whenever I charged or changed the battery the battery gauge light would turn off. Only to turn on again later on. This was my 4th alternator replacement. I was wasted I didn't want to work on the X5 anymore. I got so fed up I put the X5 into storage for two years.

Seven months ago I was at a bar on Staten Island NY where I ran into the tech who rebuilt my alternator twice. He remembered me and after a few beers. I told him my water-cooled alternator was going bad again. He said "yeah I figured that much." I asked him why. These are his exact words: "I have been rebuilding starters and alternators for 30 years and ever since CHINA began mass producing ALTERNATOR DIODES ALTERNATORS HAVE BEEN FAILING. HOWEVER AIR-COOLED ALTERNATOR-NOT SO MUCH. They all had one thing in common he explained-cheap Chinese made diodes inside the alternator that can't withstand the heat so they fail."

In laymen terms he explained that cheap diode failure rate is highest in water-cooled alternators due to heat in certain LATE MODEL BMW'S and LAND ROVERS. The fried diodes causes the battery current to start leaking power backwards. THUS CREATING A PARASITIC LEAK. When most or all of the diodes are fried the alternator no longer charges the battery. HE INSTRUCTED ME TO DO A SIMPLE TEST. (1) DISCONNECT THE NEGATIVE BATTERY POST. (2) DISCONNECT THE POSITIVE CONNECTOR FROM THE ALTERNATOR-TAPE UP THE POSITIVE CONNECTOR REALLY GOOD. THE FINAL STEP WOULD BE TO RECONNECT THE NEGATIVE POST TO THE BATTERY. Two days later I used my fluke to check the battery and the power loss was negligible and the battery held its charge. AS HE PREDICTED!

For whatever the reason BMW engineers believed it would be better to place the alternator inside the engine to be cooled down by the circulating coolant from the radiator. I had already replaced the radiator and the water pump with expensive high-performance parts. The elderly tech explained the following:

THE PROBLEM: Aftermarket water cooled alternators you buy new or refurbished at your neighborhood auto-parts stores start to fail slowly but surely-DUE TO HEAT. Re-built water-cooled alternators are a little better-maybe 2 year later they go bad too. A new water-cooled alternator from the dealer will definitely last longer. However the new original equipment 160 amp alternator can cost between $1000-$1200. For me its the work; the constant struggle replacing these hard to get install heavy alternators and taking everything apart again and again-it is exhausting.

My new friend gave me some advice.
He said I should buy a higher performance water-cooled alternator in the 240 to 300 amp range-brand new no refurbished or rebuilt. Since the these high performance alternators have regulators. I shouldn't concern myself with the extra power destroying my wiring system-as long as the problem isn't the wiring. The alternator will run between $400-$700. He recommended 5 companies and after an doing my research. I decided to take a leap of faith based on his recommendations. I chose POWER BASTERS because the reviews were stellar-the best.

I purchased a brand new 240 amp water-cooled alternator in May 2020 from POWER BASTERS. The alternator cost me $544 tax included. I immediately noticed the difference. My 2003 BMW X5 Felt peppy. The battery warning light shut off. The alternator endured the summer heat with the air conditioning and the electric fan constantly running. Almost 7 months later it is still working fantastic. Yes it did cost me $544 but the price was way better than what the dealer would of charged me for 160 amps. I am happy having higher amps-240 amps. I am very happy with my purchase. So happy that almost 7 months later I decided to share my experience with POWER BASTERS and anyone who may have the same X5 problem. I apologize to POWER BASTERS and the reader for this long and drawn out review. However if this review helps even one tired out X5 owning soul I believe it was worth it. KEEP UP THE GOOD WORK POWER BASTERS

Had mines running for month's now figured I'd come back to write my thoughts on it. At first I had issues with low voltage them a rep from PB told me I should consider a big 3 upgrade. I did the Big 3 and I didn't have to change batterie from AGM to flooded. I have 3 AGM's I have tested with this alternator a North Star, Die Hard and optima.
North Star consistent 14.4v
Die Hard consistent 14.6v
And Optima at. 14.1v
I have multiple amplifiers running lighting and accessories and the alternator shows no signs of struggle. I am giving there alternator 5 star rating.

I have a 97 jeep grand Cherokee limited and a 97 dodge ram magnum with a 6 inch lift and 35s on it but I like off road lights both of these vehicles have a 318 5.2l v8 in them and if you know motors the 318 is bulletproof you can bet the crap out of them and they keep going but my jeep has 16 4 inch off road lights and a 6 inch LED light bar and a 24 inch LED light bar and 2 12 inch subs 4 6x9s and a 3000w amp and my truck has 20 6 inch Led lights and 2 10 inch subs and 4 6x9s and a 4000w amp well on both of these vehicles I can turn all the lights on and crank the tunes and the high beams dont even flicker at all I run all my grounds back to the battery so it's not bleeding power out into nothing and I've never had a problem but 400 bucks is all most 3 times what a alternator is worth but you get what you pay for and I've only had to replace one because of a water pump blow up some how and the peaces took the alternator out with it but that was a freak accident that I've never seen and probably never will again but 5 stars all the way

This piece of equipment definitely changed my outfit. My car would dim every time the bass hit but powerbastard changed it. No longer do I deal. Great product

I needed a replacement alternator for my car due to my current 90 amp not holding charge (audio system). So i found Power Bastards online and i knew this was perfect. Still running strong and no issue or problems thank you Power Bastards. You do not need to have a loud audio system, just in any general cars, I highly recommend to everyone and this will save you a lot of money! I would buy another!

14v rock solid, you guys rock!!! Ive tried so many other companies. watch out for the Chinese garbage for sale ! will be ordering more!

I recently purchased this high output alternator and it delivers true amperage. Mike was very prompt with his customer service and I'm completely satisfied with this product. My battery doesn't drop below 14.2 at full tilt sitting idle. Beast of an alt. Thanks!!!
