Z-Tube was a Great Addition!
The Z-Tube looks amazing on my 2004 FX35 since installing. Definitely gives my FX35 a nice growl and less engine annoyance, I also paired it with a K&N air filter for better performance! Installing the Z-Tube was pretty simple, took about 30 mins and absolutely no issues with the tube itself.

Gen 3 Intake for 370Z 2018 Model
I own a 2018 370Z. Install was not too hard. I believe hardest part was making everything angle correctly. Had a couple minor clearance issues with some screws that went back into the front bumper bracing that holds the hood patches and what not I just changed out the bolt and added a shorter one to keep from rubbing the intake. Biggest upsides I noticed immediately was it opened the car up. Exhaust was a tad louder. Gas mileage I was getting on avg around 18.5, it opened it up to actually 19.9, I’m now seeing 20.1 if I drive smart. No codes were shown after install was my concern before the upgrade but had no issues there. Only thing I was mad about is I didn’t have a Stillen sticker on each side just on one side.

No Difference
I ordered these instead of the Gen 3 because they were out of stock I notice no difference with the gen 2 just buy the Gen 3 don’t bother paying 500 for a deeper engine noise.

Nice product. The fit and finish could be better. Did not mount and fit well, I had to make adjustments, custom grommets, and it could of had better mounting. They could have built in mounting points for the stock brackets.
