They dont replace the 5th and 6th ports. All they are, are inserts that are placed into the 5th and 6th ports sleeves.
No, they do not keep the aux ports open all the time.

I had Rob install the inserts into my 6PI sleeves a couple years ago when I was installing a Mazda reman. Rob said that he uses Locktite as an adhesive. If I recall correctly, that the inserts have some radial curvature to them and wouldn't be able to enter the engine even if the did debond from the sleeve. This was one of my original concerns about the sleeves. I haven't had any problems with them since I put them in a couple years ago.

I dont think anyone really knows. I have heard as little as 1 to 2 hp up to noticable gains. I have them on my car but I have not been able to test them yet becasue I am still taking it easy on my engine.

I was giving an example of what I have heard. Alot of people say they notice a nice increase, and if you have rebuilt an engine you will understand how these things help smooth the flow of the stock 6pi. It is very hard to really know how much is gained by these sleeves, I do know that I have heard that someone only found an increase of couple of hp, however no hard evidence was shown.
As for the "risk"...well I took apart one of my engines that I had installed the sleeves, one of the sleeves had backed away from where it was supposed to be installed, this was before all the news of the sleeves causing problems. If you goto pineapple they now have directions that should cure the problem.
I have my aux ports slightly ported and since I was rebuilding my engine I installed them. Are they worth it, I havent made up my mind yet, however I dont think they can hurt. In the end, I paid for them and I am going to be damn sure that I use them. If you have some cash to spend buy them, otherwise I would upgrade other parts of your car first.

i do wonder what the hp gains on those actually are. the only problem is that if you are going to tear apart your engine, you are usually doing more than just inserting pineapple sleeves, like porting or a rebuild, so you wouldn't exactly be able to dyno it before and after. regardless, look at your stock sleeves and the PR sleeves. doesn't it just make sense to put them in? i mean really. that ninety-degree angle just stops the air hard i'd think.

I felt a very noticable gain. Atleast, for a n/a car. The way that Rob explained it to me, is that at very high intake speeds, the intake charge will actually hit the end of a stock 6 port sleeve, and slow down the charge behind it.
I think it was Rotarygod, that said that the intake see's speeds in upwards of a couple hundred mph! CJ
