I just bought a G37x sedan, slate blue w/navi memory seats, etc. Awesome car, love it. I just bought the Stillen Gen 3 intake and was looking for suggestions on other performance mods I can do. I was thinking Berk HFC's, but other than that I'm not sure what else I should be considering. Are there better HFC's than berks? any suggestions would be appreciated. Just looking for go fast mods for now. Chassis is tight so I'll tackle that later. Same for brakes.

I did search and found a ton of threads, but conflicting info so I wanted to ask myself.

 

Fast Intentions Resonated HFCs (FI RHFC) have many posititve reviews. I'd get some if I was looking to upgrade! Also, no rasp

 

what about Berks or Stillen HFC's for that matter? Also what other bolt on mods are worth doing on the G?

 

Check Z1's HFC, Kinetex is an option also. Both under $400 I just got the Z1's installing them next week when the arrive. FI isn't the only way :/. For sure at over $600 EH
don't get my wrong I loved my FIRHFC's (Should have sold them) Just wasn't looking to Spend 600$ for HFC's again.

 

does anyone make ceramic cats? metallic cats tend to stink in my previous experience
