Do You HAVE To Put In...

You don't HAAAAA-VE to, but without a sleeve, the direction and velocity of the airflow is compromised. The stock opening has no shape to it - just squared off at the end. The air/fuel basically will run smack-dab into a wall, then have to go straight up into the combustion chamber.
The Pineapple racing sleeves give the air/fuel mixture a nice, smooth ramp to enter the compustion chamber, thereby "placing" the mixture more precisely and at a higher velocity.
Sorry for the non-politically correct analagy, but it is like hopping in a wheelchair and trying to go up or down a flight of stairs. Yeah, it's possible, but not very easy. So just take the access ramp, right??

Get the Pineapple racing sleeves if you want to upgrade your aux port system. Ripping them out isn't going to improve top-end much (there are better ways) and you'll lose out big time down low. This is a good system, leave it working properly.

I have broken one of the sleeves. When I was wiring them open, I accidentally broke off the end of the rod that attatches to the actuator, and now, the sleeve is locked closed. I can feel the car choking at high RPM for air. I need a quick fix, and I am kinda broke. I really didn't mind the cut in torque, and the few days the port was open, I really liked the feel.

i run mine without sleeves, i dont notice much low end power loss, i chug around at 700-1500rpm in gear a lot, its ok to do, but the pineapple sleeves put in an open position would do MUCH better, but yes it is driveable without them

I will just leave them out, till I get this damn ticket taken care of, then get some Pineapple ones. Hey, Agent_D, got a quick how to? Like what do I use to plug the holes on the lower intake?

If you a good little lad and can send me your gauge cluster i will put them in for you... I used to sell them but stoped about a year ago. I will email you with the different styles I have.

The eddy losses of air being PUSHED through an opening is substantial, but not if it is being sucked into the opening. The pineapple sleeves are too much money for not enough gain, IMO.

It'd be easy to use analagies, theorize and speculate about this, but nothing tells the tale like a before/after dyno sheet.
Which I'm sure we'll be seeing promptly from the source themselves, Pineapple, or someone else.
But think about it. Say you *JUST* get five peak hp from using the Pineapple sleeves vs. yanking the stock sleeves. It only cost ya fifty bux. What other bolt-ons offer that performance/doller value?
These sleeves woudl also pave the way for better flow as more intake/exhaust restrictions are removed, eg. adding cold-air intakes, headers, cat-backs, etc.
