how difficult is a plenum install?

[dmassey1010]

time and effort?

i just got an 06 g35 sedan and plan on upgrading just want to know how difficult it would be to do on my own.

very easy - most people use a plenum spacer as its been found to be the best option so far.

It really depends on your abilities. Not a difficult job, but go slow to avoid any mistakes. If you have a 6MT, I'd also do the MREV2 mod. It really wakes up the car!

[dmassey1010]

alright thanks any idea on what the best size is 5/16" or 1/2"? whats the difference?

[joe603]

5/16. You will not be able to reinstall the engine cover (without modifying it) using the 1/2 spacer.

thanks, appreciate the help.

Make sure you have an inch pound torque wrench and do not over tighten the middle bolts.

inatall its self is not hard, there are alot of bolts like 18-20 that hold the plenum down, and there is a torquing pattern to follow. make sure you have time set aside to do it right. This not a job you want to rush, else you end up with a air leaks and Error codes.

The install will inprove mainly the Mid range power of the car 3500-5500 RPMS. right where its needed Also the engine sound will be louder and more throaty

are you 6mT or 5AT?

[dmassey1010]

5at

[joe603]

Then you DO NOT need the MREV2 lower plenum mod...

The AUTOs already have that plenum design. The mod is for 6MTs.
