Thank you BLACKNIGHT07601 for that infromation, I am Las Vegas and it rains a little bit every once in a while and It doesnt get very cold neither so I think I will do what you said Buy an Ebay $40-$50 CAI and replace the filter to a K&N.
My biggest concern was the warranty problem but I guess I will keep the stock one handy if I need it.
I have also seen some people with a long pipe with 2 filters, 1 in the bottom like CAI and other in the middle like SRI, any info about that? Thanks
