Question about upper intake plenums....

I was considering buying the C&L plenum, but saw the polished Accufab model and was interested in purchasing it along with their polished throttle body. My question centers aroudn why C&L has a different model for the 99-2001 and 2001 and up cars, while Accufab has just one model.

here is the link:

Am I correct in thinking I can order the Accufab model and not worry that my car (a 99 GT with a 2001 motor, dont ask, long story about a broken crank sproket) will be fine?

Thanks,
Mike
