I don't think there'll be any harm toward your Navi and Radio.

FSportIS

iTrader: (13)

I think Sewell also sells the F Sport intake tube itself for like $130 or something which is similar price with the Joe Z which is also a tube itself. It should work with the original lower box as well. I'm just thinking outloud.

I installed the whole F Sport intake though and for 3 years+, I'm still very happy with it. Congrats on your purchase, enjoy the sound and pay more gas
