Product Description

The Z1 Motorsports Silicone Replacement Intake Couplers replace the failure prone factory rubber intake couplers on all VQ35DE equipped Infiniti G35's. Over time the factory couplers crack, creating harmful intake leaks that result in lean running conditions.

These are the last intake hoses you will ever need. Unlike conventional stock rubber couplers that deteriorate over time, dry rot, and ultimately crack this silicone will stay soft and never degrade. Best of all they cost far less than new OEM rubber hoses!

Z1 Motorsports offers a full line of silicone hoses for the G35 that will be the last hoses you will ever have to purchase. There's no reason to consider anything else.

Available in Black, Blue, and Red.

Intended for use with OEM intake ONLY.

Fits:

  • 2003-2007 Infiniti G35 Coupe
  • 2003-2006 Infiniti G35 Sedan

Looks great and feels quality but the fit was very tight and took alot of persuasion to get on.(get the extra clamps)

I ripped my OEM coupler trying to install my oem intake after radiator fan replacement. I thought I had to buy an aftermarket intake to fix the issue. I quickly searched on Z1 to see if they had a solution. I order these and problem was quickly solved!

Look great. And work exactly as advertised. Im using them on my stock intake in place of the accordion style. G35x

Little rough on the install and one of the clamps were broken but works well

Works as should and good replacement for those worn stock hoses.

Great replacement for torn OEM couplers. However, the length and toughness of these makes it more difficult when you need to remove and re-install the intake tubes. I ended up trimming a half inch off each end of the straight coupler to make it a little easier when you need change air filter or spark plugs.

Had these installed for 4 years and see no degradation or deformities. Good quality.

I prefer the OE parts, but for the price difference, these work fine. I’m a little concerned about the lack of flexibility, but it’s been over a year with no issues.

Ordered these along with clamps and the throttle body gasket; everything arrived relatively quickly. Parts looked and felt solid, definitely fells like these will last longer than the OEM couplers. Once installed, everything fit snug, just like OEM fittings. Looks pretty good as well (went with black). Would recommend to anyone who’s looking to replace old or damaged couplers for their G.

Great quality, fits perfect with the stillen z-tube intake. Definitely recommend the add on clamps, can’t beat em for the price.

Nice fit for the G35 with Stillen Z-tube. Feels like quality silicon. Wasn’t too tight or too big

Great fit, the bands that I had ordered to attach these were too small, but it was just a couple dollars everything else was on point

These couplers are a excellent cost effective way to replace dry rotted and cracked intake couplers. You lose a little flex when reinstalling your intake pipe but you get a longer lasting better looking product in the end.

My original coupler cracked with the heat and these replacements work great. So for no issues. Very happy I bought and it looks better than the originals.

Perfect fit, build quality, and looks great. Exact specs of oem, so install was as quick as you can install couplers, and it brightens up your bay. You cant find these for a better deal or quality anywhere else.

Fit perfectly with Stillen Z tube and stock box. Recommend picking up two clamps with them as the stock clamps on the post MAF hose will likely be an aggravation.
