jms,
if you want something a little different and want something custom made. like have the maf in a different place that is possible too. but for the cold air kits id like to get alot of them ordered so the price will be cheap so that there can be a better market for parts for 2.5 owners. if you require something different pm me and i can get it for you. of course payment will be upfront for it since it will be custom made. but be rest assured this will be quality and your moneys worth.
