ok so in other words it might help but, wont hurt sorta deal.

 

the gains are so small (if any) from doing that though it's almost pointless. besides, anything you do around the intake anyways you run the risk of introducing harmful particles and substances to the engine. the only real way to greatly increase flow is to port the head, do exhaust, and throttle body and intake ducting.

 

well i might as well give my next mod list, 4.0l trottle body swap/ bored to 63MM, 4.0l helix spacer bored to 63MM, intake manifold also bored to 63 MM, thats just as soon as i can get the parts to do it. and as for particlel put an old sweat shirt over it, exhaust is a glass pack(stock with cat), asnd intake ducting nahh like the red better,if anything id rapp the headers and exhaust maniflod 1st.
