Group install of Iso Thermal gasket
On saturday, Maxpower and I installed our new Motordyne Plenum Spacer Iso Thermal gasket and Coolant Control Valves. It was a good thing we decided to do it togeather, as it was more difficult than we expected. The instructions pretty much glossed over the "gory details" that we encountered. We started on my 2003 G35 Sedan at 9:00 am Saturday morning and finished it at 12:30! We learned so much during my install that we were able to do Tom's (Maxpower) 2005 G35 Coupe in a little more than one and one half hours. The following are some pictures of this dual install. Enjoy and learn

Removal of the upper Plenum required all the hoses around the throttle body to be disconnected. This was a real pain in the a** and does require two people to do it.
The fifth picture shows two bolts that were required to be removed before the lower plenum could be taken off. These two bolts were not mentioned in the Motordyne install guide. The fourth picture shows the plenum spacer and the two gaskets removed, sitting on the workbench.

Now let's get the lower plenum off! Wait! The instructions don't say anything about all the other bolts that need removal....
#1)Another pic of the two extra bolts needing removal from the left rear of the lower plenum. #2) The bracket that has the 3 stamped on it needed removal as well.
#3) Showing the three bolts at the front bracket that also needed removal. #4) shows the rear lower plenum bolt removed #5) the front lower plenum bolt removed.
These bolts are in addition to the eight documented bolts within the lower plenum that attach it to the intake manifold.

Remove the lower plenum and expose the intake manifold! Pic #1) intake manifold. Notice that the second intake appears to be completely clean while the others are discolored. This worries me! Pic #2) looking downward into the intakes. Pic #3) the lower plenum as it sits on my garage floor. Pic #4) the bottom of the lower plenum that makes contact with the intake manifild gasket. Pic #5) another view of that beautiful intake! Also notice in pic #1 how the right hand side near the oil filler appears to be oiled up. I never spilled oil when I changed my own oil...I bet the Stealership spilled oil all over the engine when they did their oil changes.... Lousy gorillas! I took Mineral Spirits and cleaned it up in pic #5.

Oil up the Iso Thermal gasket and place it on the manifold. Then reverse the process. Man...my back was aching after all the leaning over the engine.
Pic #1 is my 2003 Sedan getting put togeather. Pic #2 is the 2005 Coupe lower plenum exposed. Pic #3 is the new Coupe again. It is a 2005 with a little more than 4000 miles on her. Quite a bit cleaner than my 69,000 mile 2003 Sedan! Pic #4 &5 are the Coupes intake manifold. Notice how clean the intakes appear.

Put everything togeather and enjoy the good work! I had bought a Sears inch pound torque wrench for the initial plenum spacer install. It really came in handy! My magnetic pick up tool also came in handy for the bolt I dropped in Tom's engine. I actually dropped one bolt and one plastic plenum post spacer down my engine, forcing me to remove the lower engine cover to retrieve them. Man..that really sucks when you have to break stride to fix your own Fu*k up....

Here is a nice gathering of Nissan products, Tom's 2005 G35 Coupe, my 2003 G35 Sedan and my wife's 2000 Maxima. After we finished the install, I broke all my rules and cracked open the beer before 2:00 pm...hehe We took a spirited drive around the business park to check out the work. After about 5 miles of driving, we pulled over and popped the hoods. HOLY ****!! The plenums were just slightly warm, this mod has made a huge difference. I tried to touch my plenum after about 1 hour after shutting her down the other day and it was too hot to touch. So this mod MUST result in cooler air entering the intakes.....more HP.
