## Questions & Answers

**Q: will this fit an 03 base model ?**
A: Fits all 03-06 VQ35DE 350Z.

**Q: If I had a 2004 auto 350z, I would only need this spacer?**
A: I have a 5/16" on my G35. The 350z has the same intake manifold as the G35 so there should not be any fitment issues. If u are up north get the isothermal plenum spacer because of the cold weather. If you have a strut tower bar get a 5/16"  because the tower brace will not clear the 1/2" spacer.

**Q: Is a plenum spacer needed for 2007 g35x sedan with the 35VQHR motor?**
A: No don't waste the money they are only needed for the vq35de which was in the 03 to 05 only because of the airflow restriction there was to the front 2 cylinders

**Q: Whats the difference between the iso,simple,copper plenum spacer what would be a better one for my 2007 g35 coupe im located in utah?**
A: If it's hot all the time u definitely don't need the copper one. Its only for places that it's severely cold a lot and it's your daily driver. So if it's warm all the time and just sometimes cold just get the normal one.

## Customer Reviews

### ⭐⭐⭐⭐⭐ Motordyne spacer
*by P***M on November 18, 2012*

This is a decent product. It will yield noticeable power gains and give your engine a little bit meaner growl. I'm glad I put it in!

### ⭐⭐⭐⭐ Pleasantly surprised
*by W***C on March 29, 2016*

Installed this on a base model 06' Z with a Jim Wolf popcharger intake. My first impressions after installing was that the car was slower, weaker, had lost torque down low and I just wasted @$400 on placebo parts. After a few beers and a bit of research, I found out you have to do a TPS relearn, Throttle valve closed relearn and ecu reset. After doing these 3 things and driving around there is definitely an increase in low and midrange torque using the butt dyno, the car pulls harder than stock in 2nd and sounds healthier with a deeper growl added to the engine note. All in all I'm happy with it. The spacer does provide some slight gains in hp & torque.

### ⭐⭐⭐⭐⭐ which was fine.
*by W***L on March 1, 2016*

Well crafted product, speedy delivery. Paired it with the MREV2 lower plenum and man-oh-man! A complete difference in growl and power surge at the 3500rpm marker. All parts were included, however the instructions were completely the wrong ones, and had no correlation to this part. Had to look up the instructions online, which was fine.
