A regular spacer? Maybe.. If it's looking for more plenum it will work.
I've had great luck with the HVH super sucker 1" spacers. They are truly a work of art. I've seen them on a dyno make more power on every engine I've seen one bolted to. Back to back 10-20hp. Same in tq.
Coincidently Nitrous Express's new trinity system uses a plumbed version of this spacer.
