Aftermarket parts do not exist for the first gen H body cars. You have to make them from scratch or make parts from other cars fit.

CAI can be made from just about any pipe that will fit with a filter on the end. Search the forums, this comes up all the time.

Another simple mod is to open up the exhuast with a high-flow cat converter and muffler.

And another is to upgrade the stock Magnavox ignition to a higher-powered Delco Type II ignition.

Again, a forum seach will yield all the answers you need... I think most of that is in the Techinfo section of the site as well.
