looking for the most brightest bulb that can fit 99 audi a6 quattro thanks.

 

Go with PIAA...Dont go with Silverstars or AEM...PIAA is the most expensive and for good reason. They are brighter, built of better quality, and last longer than any other bulb I have installed. I ave used PIAA in every car of mine for the past 10 years with NO burnouts or problems. Plus, most models come with a full 1 year warranty.

 

Where can I find the PIAA brand? I used Silvercrap and they lasted about 8 months. Thanks for the info.

 

You can go to www.piaa.com or you can go to EBAY for some good deals. Some of your specialty auto shops in your area might carry them. Best best is to try the website and then do a google search for PIAA.

 

I agree with prbayha, PIAAs are the way to go. They are the best quality and will last forever. My mother-in-law's Camry has my old 9004 PIAA bulbs I bought in '99 and are still going. My ion crystal fogs are going on 5-7 years I think and still look perfect.
