I have a 03 Sedan and I just installed a Ztube with the Stillen Airbox from G35parts.com

I love how it pulls harder on the top end, seems like a good power gain above 4000 rpms.

My question is, what do I buy next to complement it to add more power - 5/16th iso or 1/2in iso or Mrev2?

Is there something better I can do for under 4-500 bucks?

Thanks for any help guys

 

5/16th spacer will do more for you than the mrev2

 

motordyne 5/16 spacer FTW!
after the install i felt more power through low range
and a killer sound combo with my fujita intake

 

Thanks for the quick replies....

Can you tell me why the 5/16th over the 1/2in?

 

5/16th adds lower end power, 1/2 adds higher end.

Mrev is more for rev up engines (not yours)

 

3.9 gears.

nice easy explanation....thanks you

I love gears, I had 3.73's in my last car....but does it require a tune after install?

thank you I will check that out now..


Do I need anything else to install the 5/16th besides what comes with the kit, like gaskets or anything?

 

you should be good man as long as tou buy it from tony at MD or a vendor since they ship the kit with all the bolts and washers


also if your gonna do it your self get your self a proper torque wrench, these bolts snap so easy its not even funny

 

o an i dont think you need a tune for gears but once you do all your bolt on mods a tune is wroth it IMO

 

Awesome thanks so much...

I got .4 sec in the 1/4 when i did gears last time, i may have to look into this more for the G to see what people get from 3.90's..


Gonna go order the 5/16ths spacer from G35parts.com now...preciate it

 

no look on here there was a sale by one of the vendors i think he had them cheaper
