where do i find a good cold air intake for a 2001 sl1?

You can buy one off ebay. Then put a good K&N airfilter on it. Right know you are look arould 30 to 80 for piping + shiping. Then 40 for a K&N airfilter. You can run the airfilter that it comes with but after 6000 miles most likly you have to replace it. AEM makes one for are car too. It is arould 306.04 and shiping is free And it comes with a K&N airfilter. I would go the ebay way bc it is the some piping.

Here is A photo of the ebay one
