I'm looking to buy a cold air intake for my car. The problem is that I can onlt find a short ram intake and not a two piece that can convert from both short ram to regular cold air. Anyone know of a brand that make a two peice for a 2002 IS 300? Another question is how big of a difference is there between a regular cold air intake and a short ram with a heat shield? I'm new at this and if anyone could answer either of these questions that would be awesome, thanks.
