Do you see any problems with using a 4" cold air intake with Spectra Filter to the TB for a stock N/A engine?

I'm building a custom setup and was hoping this wasn't TOO big?? If it is, then I will have to use a reducer in my piping right off the TB instead of using the reducer at the end of the pipe where the filter will attach.. I plan on reducing to 3" at the filter.

 

It should be fine. Not sure there is such a thing as "too big"..... In reality, for a pretty much stock motor, the stock system is more than big enough.

 

This ^^. Without supporting mods to the intake, heads and exhaust, a "cold air" intake won't do anyting but sound cool.

 

Is there a different TB out there that I can bolt on to allow more air into the intake? I am not a fan of the stock TB... JY or New?

 

TB is a start. Still won't flow any more air with stock heads and intake and exhaust.

 

Yea, theres a guy that sells them on ebay or you can also get one from Hughes. I got one from the ebay guy(his account was 99blkdart iirc-if you're interested in one lmk and I'll see if I cant find it in ebay history ) and noticed an improvement in the butt dyno
