Plenum Spacer or Replace the whole stock plenum with an aftermarker one...which one will increase my horsepower the most? ive gotten mixed reviews. I know you guys are experts. Thanks a bunch

 

there has been discussion about this.. Try using the search engine and im sure you can find the thread

 

Flattery will get you everywhere. Check the Sport Z magazine plenum vs plenum shoot-out.

 

how do i get to that sport Z magazine shoot out thing? and what do i type into search...thanks for the help!

 

which one would u guys go with????

 

cost wise, spacer for me

 

i want performance..price doesnt matter..which one gives more in your opinion?

 

I don't remeber in what mag this was in, but they placed a Kenetix Plenum in, and it gave the car 10 hp to the wheels on the dyno. I think you'll only get around 7 out of just a spacer. Plus if you go with a new plenum, you will have bigger gains in the future if you plan on going FI....

Just my 2 c.

 

Hey, it was in an import tuner if i remember correctly. It also gave results on the plenum replacement on a Supercharged Z33.

 

stop posting replies like this ...... i am sick of it....not everyone buy/have time reading sport z magazine.......

 

just search this forum for the results of that test. they are on here. basically the 1/2 spacer from motordyne had the highest performance, followed by a 5/16 inch spacer both made by motordyne. Just go with a motordyne spacer, unless you eventually plan on going FI, in which case the Kinetix manifold is supposed to be pretty kick a**!

 

I would not tell another member to buy a magazine. The results of the comparison testing can be found here:
