hey guys so I have an oem throttle body and a p73 intake manifold,

I want to add a p2r tbs with the 2 gaskets and an im thermal gasket. if I hop on corsport which one do I order? is the im gasket interchageable? And for the spacer they have different gasket diameters 60mm to 70mm which one do I order?

 

Don't buy either. Leave it alone and put that money towards something that will make an actual difference. Put it towards better oil or something.

 

any other opinions?

 

That spacer is a line of BS dude. All it does is make the air intake sit 1" further away from the TB. If anything buy a BPI stack and filter for your air intake if your looking for gains.

 

how exactly does a velocity stack work?

 

velocity=speed. pretty straight forward. Higher quantities of air moving faster and more streamlined will make better power.... im no scientist so google it.

 

O ok and how do you filter that out?

 

I'm not going to spoon feed you any more. Google "BPi velocity stack" and go to their website. Read up on all of this info and they check out the Stack and Filter combo kit.

EFF it here I'll do it for you to save another post.
