Hey guys, what kind of power increase would be expected with these on a L27? I was planning on doing the cold air induction and a few other mods too. Is there some power increase in this?

Thanks,
Chris

5hp? You're not in the MUST HAVE category as the L67, as you flow considerably less, and don't have the advantage to add flow easily.

If you're going to take them off anyway to fix cracks, by all means, work them over.

Well I was going to buy a used set and fix any cracks in them, then port em! I have never done something like that before so I figured if it was worth it, I would do it on another set incase I "F" up.........
