I'm thinking about getting an APS cold-air intake and I know that it connects to the stock rubber intake tube. Thing is, I have an HKS RS and I was wondering if the APS would bolt up just fine, and if not, what intake pipe out there would bolt up to the APS? Thanks in advance guys!

 

As far as I know as long as you don't have to reposition the maf then you should be fine. In other words any intake pipe that leaves the maf in the stock position will work with the APS.
