Looking into installing HFCs
 

Hey guys, I just ordered a Nismo cold air intake and I'm also wanting to install some HFCs, but I'm not sure which are the best on the market, or the best for our car. Thanks in advance guys.

Not to be rude, but this forum is full of threads just like this. You could just spend some time researching what is already out there.

depends what you are really going for and if the hiss sound will bother you or not. if you aren't bothered by the hiss sound a straight test pipe would be beneficial, if you want a refined tune you should check out some resonated HFC's, here's ours

Re; HFCs...there are plenty out there each w/unique experiences here's mine
 

with Nismo S-tune exhaust and nismo cai...after researching forum decided on CNT Racing HFC. Cost was only $299 + free shipping, and my mod worked out and I'm very pleased.
Nice deep tone, and after a cai leak (I removed them during install) what I thought was a cel warning of o2sensor, was actually intake leak.

Cel has corrected itself and turned off. I have a pre install short video (idle) I plan to upload this weekend along with a post install one.

I have Fast Intentions and I highly recommend it. I also considered Berk, Z1, and Invidia before making the final decision. I think, you'd be pleased with any of them.

Thanks for the tips guys. Did you have any problems with the FI? Like any check engine lights constantly going off?

+1 on CNT. No fitment issue, no CEL, good price:tup:

Berk Technology, hands down.

Stillen is my favorite because they use oem crush gaskets from header to cat lol. no leaks for me! but that has all changed now lol
