$180 on amazon
I am about to purchase it, just making sure this is legit. Because it seems really cheap compared to other sites.


EDIT:
Installed them today took about 30 minutes. Had one minor issue, suppose to use in/lb torque wrench but instead I used ft/lb torque wrench and just divided the feet to inch. First time I started the car the engine had a rough idle every 5 seconds or so. In the end I found the issue, the plenum bolts were still not tight enough. So I gave it a few more turns on each bolt and voila everything is working perfectly.

 

Just get one from Z1. Z1 plenum spacer. Better product

How is it exactly better?

 

Your just getting a basic spacer, same as this. Except this is cheaper.
Also I've purchased 2 of these, for different cars and have never been disappointed

 

Thanks, the link you gave me doesn't tell me if its 5/16

 

I assume it is man

 

From the link on Amazon it's sold by OC Infiniti, which is a sponsor here, so it's legit. And so is Z1. Either one should work for you.

 

But Z1 is the S%IT!

 

Just realized OC infiniti is around 15 minutes away, going to pick it up right now

Everyone is saying how they can feel the difference with butt-dyno, hopefully I will too.

 

Don't forget to mention you're a member on here. Happy shopping!

 

5\16 is the size you want. 1\2 not as good as 5\16. I f you live in a warm climate you dont need throttle body heater.

 

Updated OP

 

Looks good, now go feel the difference with your butt-dyno!

 

Been flooring this car for the pass few days, I can definitely feel difference in low-mid RPM range.

Side note, why does every car feel like they want to race me?
