Looking to order a short runner intake this week, their seems to be 2 types floating around and look like they will give a different throttle body position or seems to be pointing down at an angle, does one make routings pipe work any easier or cause and problems price seems to be similar, also is their any need for a bigger throttle body

I have used the bottom one in the past, worked fine. No need for bigger throttle body.

Changing to a short runner? Lol

Was only asking as I'm sure I read before the OEM is plastic limiting boost you can run.

I’ve had 20psi through stock manifold, no problem.
With a short runner you will have less off-boost torque but more top end power. Stock manifold picks up a lot of heat from the engine as it’s sitting over it and if you have a turbo setup, it’s also picking up a lot of heat from back there.

Ah Interesting so your exchanging your lower torque for higher end. That's not bad 20psi bet was flying with that
cheers for replying bud.

It’s a few years back, it’s much faster now, even with less boost.
