Installed the Z tube on my '05 G35 coupe (my first mod) in about 20 minutes and I think the car was faster even before I took it out for a test ride . The diy guide on this site and others made it very simple. I took the car out on a local parkway and it absolutely howled over 3500 rpm. My wife doesn't realize what she got herself into when she gave me the green light to buy the G. Let the mods begin

 

hahaha nice....wait until you put the Plenum and High flow CATS in.....

 

or a JWT popcharger/Stillen CAI. You think it howls now.

 

congratz .....and another one taken down by the MOD BUG!!

 

i didnt notice any gains with a plenum spacer.

the Z tube does make the air flow smoother, but not sure if there is gain in it. I know i need pop charger on mine to really see anything.

so far the gains i noticed came from exhaust and test pipes

 

Wait until he throws an MREV Plus in!

 

Plenum for top end gain.....you'll notice after 60 mph

 

hmmm....im startin to really like this thread
modifications are so hard to choose from

 

Modifications are not hard to choose if you got the $$$$

Aside from that it all depends on how far you willing to mod and what you trying to achieve. I personally like mid range and top end.

 

wait...
so the Z tube increase the noise of stock intake assembly of the G35...
but doesn't it make sense that the Z stock with Z tube (completely stock) pitches out the same noise?

 

Thought you retired?
