I wanted to buy the plenum spacer manufactured by member Hydrazine. I ordered it from him on Wednesday, February 23rd. It was shipped yesterday, the 24th and I received it today, the 25th!! Talk about GREAT customer service.

The idea for a spacer is ingenious (Hydrazine is a rocket scientist) because it does what the raised plenums made by several other manufacturers do, but at a better price and the installation allows you to keep the original plenum and cover configuaration.

Other members have made very favorable comments about the perceived extra boost the spacer gives them based on their "butt-dyno". I believe that several other members have put their cars on a real dyno and gotten "better-than-without" the spacer results.

 

did you get the 3/8" spacer? I have seen a lot of feedback and data for the 1/2" but very little on the 3/8. please give an update after install and test drive. thanks
