if you have an 2005 6MT Coupe / 350z Track you can get the ISO Thermal Kit. BUT the thermal kit was made to go with the spacer so you'll have no use for the plastic plugs.. the only thing you can use is the Coolant Control Valve, Copper Throttle Body Heater, Lower Plenum Gasket.. it should still greatly reduce the temp of the air comming in tho.

You can put on the spacers on an 2005 6MT / 350z Track, fitment has nothing to do with it. BUT you will NOT see any performance gains from the spacer. Depending on your other mods you can loose power because you dont have enough resistance (iono if thats the correct word for this lol).

Everything motordyne has will work for the 2005 AT Coupes, Sedans (except the 298hp one iono if there is one), 350zs (minus the track model), and all pervious 2004 and 2003 models.

Thanks for the clarification.

Eric, I'm getting my car back tomorrow! I'm going to need your help with the install. Just let me know when we can make it happen on my car

oh yeah let me check out your ings lip... damn shiets gona look HOTTT lets detail it and go pix ***** lol

Can someone tell me what the difference is between these and what all the extra stuff is?

5) 1/2" Basic Plenum spacer (with Iso Thermal internal plenum supports) $215

7) 1/2" Iso Thermal plenum spacer (with all Iso Thermal components, Aramid gasket and CCV) $245

9) 1/2" Copper Iso Thermal plenum spacer (with all Iso Thermal components, Aramid Gasket and Polarized Copper TB heater) $295

And how much power will I gain? Is it noticeable? Whats more noticeable: The spacer or UR pullies?

Dan, I have both the UR pulleys and the 3/8'' spacer. The spacer IMO was a better performance mod, more noticeable.

Can someone tell me what the difference is between these and what all the extra stuff is?

5) 1/2" Basic Plenum spacer (with Iso Thermal internal plenum supports) $215
includes the spacer and the 6 "rice colored" plastic plugs that goes between the plenum

7) 1/2" Iso Thermal plenum spacer (with all Iso Thermal components, Aramid gasket and CCV) $245
same as above but includes a gasket that goes between the plenum and manifold. also includes a coolant control valve that'll allow you to cut off hot coolant going to your throttle body

9) 1/2" Copper Iso Thermal plenum spacer (with all Iso Thermal components, Aramid Gasket and Polarized Copper TB heater) $295
same as number 8 but includes a copper throttle body heater. if you live in cold areas (you'll need to the "hot" coolant to keep your throttle body from freezing) instead of running it through your throttle body it'll run through a coppor throttle body heater

And how much power will I gain? Is it noticeable? Whats more noticeable: The spacer or UR pullies?
if you're a 6MT and want faster RPM response then go for the pullies but it does not add much power.. the spacer will make the engine sound a bit louder and the gains on a 1/2" was like 10-15hp on the dynapack (some one +1 on that please)...


heres an idea of the gain..

- Please right click and save as.. you can see he lost by a bit

http://www.rice.sightless.net/aG35/v..._vs_kyosho.WMV
- Same coupe as before.. and he let off first at the end so yeah

I just got the car back last night... WOW!!! I love it! I was going to have my rims put on too, but I got off work too late to be able to do both. I'll probably leave to pick up my tires in a couple hours

So now that most of my major exterior work is d0one, lets start working on my motor. Let me know when my parts are in, so we can start

Can somone show me a good website to by a spacer from??? I have not been able to find one on a site.

^^^very nice thanks

Do I need the gasket and coolent control valve?

So he gained about 1 car length after the install?

Btw klumzyee, what mods did you do to get +18 whp and +22 wtq?

Mods were also made by motordyne.. you guys will find out by the end of this year.. it only applies to 2005 6MTs and 2005 Track 350zs

Can anyone tell me what the gains are between the 5/16 spacer vs the 1/2 spacer? And what advantages would the Thermal Plenum Spacer provides? Sorry but I read all of the responses and did not find any numbers and would the numbers be true for an 04 Sedan?

Thanks
