I tried an aftermarket one on my P10 and it only worked the first time...only put on 10K miles on it and it would pass the second time around. Slapped on my OEM with 125K+ miles and it passed with flying colors (this was 2 years ago before the VE).
I would buy that manifold and swap it over every two years. Easier to swap intake manifold than swapping whole engine. I thought Mac wanted to start fabbing those up...

I believe anything that is 22 or 23 years old is considered a classic and will No longer Require an inspection. Only a Outside Visual. Lights and stuff..
