I recently came across this very interesting online article regarding TB spacer reviews, worth, etc… it is very apropos for this particular unit.

Compared to a Z tube, filters, etc. . . . It was definitely a worthwhile mod for me.
It definitely gave me better throttle response in the lower ranges, as I had mentioned. It wasn't difficult for me to determine the results, because I had little to no throttle response in the said rpm range and under the said scenario.
I trust that you Bar exam studies are going well.

I could have sworn that I saw this same item on ebay a while back.

I have no idea if this will fit with my JWT TT kit, but I'll try it out... paypal sent. thx for setting this up ocg35. I'm not going to do a before/after dyno for this little thing, but I will log some data using Cipher and do a before/after with my Gtech-RR.

Just to bring an old topic back to this thread, it's not likely that the spacer grooves (which likely creates the necessary air turbulence for better air/fuel mixture) are the only factor in the performance enhancement, but the fact that intake runner length is increased.
The VQ30DE (95-99 maxima model) had "long" intake runners, helping it to create more tourque than HP (205 lb/ft & 190 hp), but fell on it's face after 5k rpms. After learning that the VQ30DE-k (2000+ maxima model) had a variable intake that opened around 4.5k rpms, thus giving it a "short" intake runner to increase hp when needed, the VQ30DE guys started using a MEVI intake to give them better top end power, but it lost a little low end tourque.
In any case, intake runner tunning is real and has been around for a while. Find more about it here > http://auto.howstuffworks.com/question517.htm
I would like to see a Dyno of the before and after not just for peak gains, but to see the impact across the entire curve. It's likely that this longer intake runner helped to gain low end torque at the lose of top end HP.

hey ocg35. sorry its taken me soooooooo long to post my review about the spacer. ocg35 already knows my opinion about the spacer, but to everyone else, i felt a slight improvement around the 2800-3500 rpm range. the spacer also made the whistling a little louder from the intake. personally, i didnt seem to feel that the spacer hurt my car in anyway, but its not going to give you anykind of headjerking power either, but for $90, you cant go wrong with this thing. sorry it took me so long ocg35. it would be a little more indepth, but i have to get back to work. lata. darren
oh by the way, im glad to see that you were able to get these things on the market.

I understand that the spacer possibly has increased the intake runner length and thus potentially give better low to mid end torque characteristics.
However, I am interested to see if people who have tried this spacer has had a plenum spacer already?
The reason that I am asking is that if you have two spacers, one at the plenum & one at the TB, I am afraid that they are increasing the effective runner length by too much? (I dunno what is too much.. I am just throwing some ideas out there)
Anyhow, kudos to everyone that has written a review for the TB spacer!!
