Whats a better high flow car. Aam or berk or fast intensions. Please get back to me. Also i dont want any check engine lights...

 

on check engine lights...prob find info on the cats themselves throughout that thread: https://www.myg37.com/forums/intake-...-cel-poll.html

Berk HFC here...and never had a CEL problem.

 

from what i understand. Tony from FI has worked on this new type of o2 sensor that is guranteed to not have CEL.

He try it first on G37sam car, he has test pipes so those usually cause CEL regardless and guess what sam still havent got a CEL i think. So since it works on Test pipe then it prob work better on HFC.

Give tony at FI a message. im sure he will help ya with what ya need and have great price. its better to call him cause he a busy guy and sometime doesnt answer right away through PM or email. hope that helps

 

YUP, same here. Got the new 02 Sensor design Bung with my FI HFC's from Tony! Said mine and Sams were pretty much the first guy's to get the new design 02 Sensor mount! And I had it on my Sedan for about a little over 100mi already, and no CEL so far! * PRAYING & CROSSING FINGERS* LOL. They are all good repitable companies. But seems everycar is diffrent! some cars get the CEL right away, some don't and some get it later, or some never get it at all!

Just FYI, alot of guy's report some slight to moderate hesitaion under 50-75% throttle on low RPM at lie around 2000-3000RPM range! I got it a little, but it's not that bad on my car. I know alot of sedan guy's and 350Z guy's have it worse! but thats about it, I do feel good gains in the upper RPM range!

 

I got FI and didn't get the CEL till now, and i dont have hesitation (knock on wood )

 

Tony has a new design to his HFC's, so don't worry about throwing a light, I would go with FI, can't beat his customer service and quality work.
