Cattman Performance, well known over on maxima.org, is selling off the remaining Place Racing CAI kits for 02+ Altimas. I bought one that's sitting in my garage for 129 plus shipping. These kits use a monster flow foam filter which is a non-oil based filter. The MAF's on these VQ35 engines are known to be problematic with oil based filters and eventually fail prematurely especially if you over-oil the filter and the oil interferes with MAF function. There's a thread over in the group buy section of nissanclub.com if you're interested:
