Im new on this forum and new to the g as well. i have a 08 manual g37s. Im coming off of a fully bolted on cammed supercharged rsx. Also owned a 350 several years back. Modding starts now i just purchased the gen 3 long tube intakes and im wondering if intake spacers for this g offer any gains like it did for the 350. i searched and didnt find anything. maybe i didnt seqrch thouroughly sorry if i didnt. any imput is much appreciated thanks.

 

Look at the 370z for G37...2008-current are the same.. as for the 350z its the G35....
Putting a Throttle body spacer adds min gains any way IMO.. 2-3hp at most... but if you have a Gen 3 like I do you'd push the tubes more forward ... I'd look to see if you have that kind of room to do so?
Add a HFC EXHAUST and there's your gains... the Gen 3 provides enough as is...
