Hey guyz, i have an 05 touring edition and i want to get a plenum spacer. after installing correctly will i have to tune the ecu, keep in mind i already have a nismo CAI so i am not sure. i have heard both stories. thanks a bunch.

 

I put a 5/16 spacer from Motordyne Engineering on my base model. Did not do any tuning afterwards but have thought about it. My butt-dyno says there is an improvement in the mid-range.

 

have u noted any problems with oil consumption or anything?

a plenum spacer can not possibly cause oil consumption

 

if i buy a plenum spacer and do not tune my ecu, the most that will happen is that i will not recieve full benefit from it? no mechanical problems can occur?

 

Mostly any modification or realtering of the intake/exhaust flow will benefit from a tune. However, a tune for minor mods like what you are discussing are not really necessary...hell if you have an EMS, then why not tune?? If you do not have a EMS, then are you going to drop $1,000 just to give your car a minor tune?? I don't want to tell you to search, but there alot of people on this forum that have those spacers and have not reported many problems, if any at all.

 

many problem? elaborate? more posts from people who have them please?

 

and how much hp will a thermal 5/16s plenum spacer give? and if not that much, can anyone think of an upgrade about the same cost that would be more worth it? it can be appearace or performance related

 

You seem so unacquainted with 350Z modifications. You appear to have no idea about what you're doing. Quit asking foolish questions like "how much hp will a thermal 5/16s plenum space give?" You need to explore this forum more and try doing some research you moron.

 

um excuse me? i think i am free to post wat i please on my forum. and as far as u telling me what to do, what authoratative role do u possess. if people dont want to answer my questions, they dont have to.
as far as the hp gain, ive heard any where from 8 - 16 and i would like to know. thanks for your post

hey, i found out that the plenum spacer does not need ecu tuning to no cause malfunctions, so that is good. does anyone have any suggestions of plenum spacers?

 

It seem like you're getting all the help and feedback you need. Have a nice day.

 

I'm glad to see that you both have come to an agreement.

Kiss & make up.

all the data is there.

contact hydrazine if you have any questions - that is his site.

 

kirradude1025, the questions you have asked thus far in this thread have been all asked and answered NUMEROUS times over the last 4 years. I see you have a whopping 9 posts as of the time I am writing this, so perhaps you didn't look over the rules & etiquette of the forum that you agreed to follow when signing up for this forum. Although it may be crude and not very intuitive, there is a search function. You can probably do a search on "PLENUM" in the "INTAKE & EXHAUST" subforum and you will find every piece of information you could EVER want to know on the plenum, how it works, why it works, what spacers are available, what upper plenum replacements are available, there is a plenum spacer shootout thread somewhere complete with dyno charts of different upper plenums and spacers.........etc, etc, etc.

Now, one of the more established members could do this search for you and come back here and post the info, but I think you should start using the search function for such basic questions as you have asked so far. Otherwise you will get tired of starting threads only to have members telling you to search. You may even get the infamous Search Kitty!!!! And you don't want the Search Kitty!!!!

 

My suggestion... Please search. Or the search kitty will get you!! Lol~

 

u will see a little gain. no need to tune

 

I sense thread failure after this post....
