OBX throttle body spacer sound?
Hi everyone, today I installed an OBX throttle body spacer on my 2004 G35 coupe 5A/T and I have this odd suction sound now during acceleration. It starts sucking from 2000rpm up to over or around 4000rpm-ish. That sound was not there before. I made sure to place in the sealing o-rings and tighten the bolts as best I could. But I still have this suction sound. Like some sort of air leak. Not sure what to do or if it is normal. I have an Injen SRAI and Motordyne 5/16" plenum spacer, did not have that noise before other than the normal Intake woosh when I reved. Now I have a suction sound going on... Is this normal? It kind of sounds like a supercharge or something... The car does not show any check engine light or no notifications of something wrong. Any ideas or advice or tips? It has me un-easy.![Icon43](https://g35driver.com/forums/images/smilies/icon43.gif)

I am sure if it was that easy to squeeze a few more mpg's and power Nissan would have already done it.

G35 sedan w/ too much money in mods
Ahh the old TB spacer debate. OP some members here have claimed HP increase, but no one has proven it with a dyno sheet. Like 4D said above our engines don't benefit from some of the more common power adders, Nissan really did a great job of squeezing almost all of the power out of the DE possible w/o going to a supercharger of turbo. With your mods your best bet for more power would be HFCs, exhaust, and a tune. You'll be pretty maxed out at that point for bolt-on power adders.
