I've got one I got as a gift 2 Christmases ago and I ran my 15.6 in my LS with it, so I assume it didn't really hurt that much. My question is that I'm building up my LS right now and am wondering if I should jump on the bandwagon and pickup an AEM CAI or if I should stick with what I've got and seems to be working.

The PRM for those who don't know is an inline filter design with an integrated genuine K&N filter in it. Doesn't seem to be marketed very well and could be crap, but its obviously not hurting my car. What do you think of it? http://www.prmracing.com/

 

looks ok...the only thing that I would say is going against it is the enclosed filter fed by that tube. That definently causes alot less surface area for the filter to suck in air.

 

PRM is definitely from a WHILE ago. I've always wondered how they fared against the AEM. I think you should keep it. I like the design...almost like the Comptech.

 

 

keep it
