Ok so I was looking for a cold air intake for my 2006 m45 black on black with navi hack just installed today and I always order from a site called auto anything.com however they do price match so whatever and wherever site you get it from for a cheaper price they match it they have it listed for almost $300 so here's what I did found this site:
http://www.carparts.com/details/Infinit ... 1996P.html they have it for $60 what you want to do is call autoanything.com and say you found it for a cheaper price they will verify the sites and prices it takes a while about 30 mins because they keep putting you on hold because they have to verify with a manager because the price is low here is the site to autoanything:
http://m.autoanything.com/air-intakes/i ... air-intake Make sure the part numbers match In this case they do thanks hope I helped some people im glad to help my fellow M users it came out to $70 even with tax and shipping the only reason I bought and price matched it was because I have never bought from car parts.com and it seemed a little shady so I recommend this method autoanything.com is straight and legit by the way you have to get the polished color NOT THE BLACK
