Will, when you get done with the heat shield, let me know how it turns out and pictures if possible.

I got mine at Crappy Tire ( CAnadian Tire ) for about 8 bucks Canadian...so you'll probably find it cheaper in the states... just be warned that you HAVE TO go to an authorized pontiac dealers ( part department ) to get the Thermostat housing gasket.. or you're going to run into issues

Ty is right.. the following kit from ebay is not a tru CAI.. it is still picking up hot air within the engine bay... you can easily modify the stock airbox into a heatshield as Will mentioned, and ducting more cold air onto it.

Ok, that shouldn't be a problem. Thanx alot.

You can get the rubber seal where you get the stat, though. Don't forget it, either. Wedge down, around the rim of the stat.

count on it. I'll post on my website....and here.

Drifter...once you get the T-stat and housing gasket, how difficult is it to replace the t-stat? (Remember you're talking to a guy who doesn't change his own oil. ) I don't mind tinkering around the engine if I have a general idea of where I'm looking.

It is relatively easy.. if you know how to hold a tool you can do it.. just make sure the engine is cold.. I don't know where the location of the T-stat is on a series I but on a series II.. it'* right in front of the Throttle Body.. it has a big black hose from the Rad that goes to it.. all you have to do is remove the 2 retaining bolts.. take out the top housing.. leaving the t-stat covering the hole, and scrap any excess old gasket off the metal ( or you're not going to have a perfect seal ) then remove the old t-stat.. ( the reason for leaving the old t-stat in is while you're scrapping you don't want any of those pieces of fall into the coolant system. Remove the o-ring around the old t-stat.. put it around the new one.. put it back in.. put the new t-stat housing gasket around the housing.. retighten the 2 bolts holding it down.. turn the air release **** on the top of the housing.. start the car for a few minutes ( this pushes the air out of the coolant system ) retighten it.. and you're done... I"m sure Will or Rat has a more informative procedure on doing it...

I remove the tstat right away, and stuff a clean rag in the intake hole. Same thing on the neck. Then I scrape.....and lightly sand with 400 wet/dry to make sure it'* clean. I also replaced the o-ring. Less than a couple bucks.

Thanks for the info - if I ever find a few hours to myself (sometime around 2005 ) I'll endeavor to tackle this project. Maybe I'll even think about a CAI as well - how difficult is it to get one put together for a 2000 Bonne vs. the older styles?

Should be identical. Hector'* intake is designed for the Series II....I'm testing it for the Series I. Ask 99BonnevilleSE about that.....
