I talked with PRJ Performance a while ago, and I'm about to get back to them with my 94 and 99 Bonneville VINs. This summer, we're going to port and polish my 94'* goods, but the 99 is doable right now.
From what 1337ssei and I believe, before we do PCM flashes to the 99 SLE I have, we should consider a cold air intake. Offhand, what is the throttle body'* opening? 3 inches? I'm going to pick up a rice pipe and cut it to fit under the hood with a filter. My 94'* K&N filter isn't the 4750, and it has a 3" hole at the back. Here'* a picture:
I'm very interested in replacing my 94'* intake tubing and filter to 4" tubing and a filter with a bigger opening at the back. The current tubing can be used for something else, and I'll order from Intense some flexible tubing for my 94. The 99 will get a rice pipe, and all will be good.
Is this a generally good filter/pipe combo? I'd like to use up a lot of this thread'* life to chatting about heat shielding, and then I'll post a picture or two of the SLE'* new CAI. Since my 94 is down with electrical issues and some more interior and engine work, I have a free filter with no replacement necessary until later on in the spring.
Also, what makes a good PCM tray? I have seen a PCM just left lying out in the engine bay with nothing holding it down. It'* been holding out for over a year, I think. However, I'd like to strap mine down, and I'm not opposed to cable zip ties. Shiny pink ones, of course.
