Which plenum spacer do you guys recommend? Kinetix v5 or AAM angled spacer? Planniing to supercharge my car soon. Thanks..

 

I'd suggest doing a little more research. Kinetix makes a replacment plenum, AAM is a spacer. Another popular spacer is the one made by Motordyne. Depending on which supercharger you go with, you may not even need a plenum or spacer (i.e. Stillen).

 

i wouldnt waste my money on a stilen supercharger.. i would go with vortex..also i woudl stay away from the space if you go FI more chances for a leak.. look at kinetix or crawfordz plenum

 

If I was you I wouldnt put kinetix (plastic) plenum on FI'ed Z. go with either Crawford or APS plenums.

 

I would check out these threads for more info on plenums and spacers

Check the results of Z Sport magazine plenum vs plenum spacer shoot-out before buying.

the Motordyne 5/16 and 1/2 yielded the most power gains from 5000 up. The kinetix was in between. The crawford showed more stable linear power opposed to the kinetix.

 

Which did you order?

 

I have yet to order only because Im waiting for non-Motordyne testing from a neutral party.

 

I would say save your money, and get the kinetix full plenum, ssr plenum, or the crawford...they are all great plenums

 

That web site appears to be dead.

 

I've already had one installed one week ago, a Kinetix V+. I would say it made the most difference of all of the mods i have on the car. When the car starts, it has this immediate air sucking noise which is not heard from the stock plenum. Torque and power are greatly improved from 3k and up. When WOT, the car just pulls like as if there is no tomorrow. Definitely a must if going NA.

 

I am running the Skunk2 (5/8") spacer along with my Vortech Supercharger. I felt a pretty good increase in power especially on the top end. The Shunk2 is the largest spacer in the market and believe me with the supercharger the more airspace the better. Nevermind the hype about leaks, put a nice bead of Black RTV Silcon sealant on the top and bottom of the spacer and you are good to go.
