New member here. Need to replace throttle air intake curved throttle air intake hose duct boot (see picture). Turns out for '05 model it's sold only as part of air duct assembly for way over $100. Couldn't find after market part after online search. Any suggestions?

Thank you!

 

I think that section of 'hose' connects to rigid plastic parts at both ends and doesn't have any vacuum ports coming off of it. If so, you can probably just replace that piece with a silicone coupler of the same length and diameter. A 15, 22, or 30 degree coupler would probably do the trick. The picture below is of 22 degree couplers on turbohoses.com (there are cheaper places to find these types of couplers):



EDIT: Cheap angled couplers --> http://www.ebay.com/sch/i.html?_odkw...egree&_sacat=0

Other options are picking up pieces of a used intake in our Marketplace section, or if you're open to going aftermarket, you could replace that section of 'hose' and the resonator with a z-tube.

 

Why would choose an Infiniti that is a high end automobile with expensive replacement parts?

If you can't afford $100 + dollars for the intake hose you might be much happier with a Honda Civic that has much cheaper replacement parts.

Shop a few Infiniti dealers that have web sites. Using aftermarket parts on an Infiniti can sometimes give you more unexpected problems than you realize.

Just my $.02

^^I doubt a hose coupler is going to cause "unexpected problems" lol. Man you give some good advice at times but I now often shake my head at a lot of your posts. If you think an 05 G is a "high end automobile" and a new owner should buy a $100 (or more) OEM intake tube for it you've lost your fvcking mind, no disrespect intended. That car is probably worth $5000 or less.

OP ignore his advice and get what you need to fix your ride where you want to. I second bigc's advice on the Z tube. He is the shizz and actually has a clue what he's talking about.

 

 

Check the marketplace for anyone selling the stock intake, most folks replace that part with the Z-tube. I'd send you mine but I just inspected it and there's a little crack on that boot so you probably don't want it.

 

 

 

 

Using my phone to measure the angle I get 25 degrees, 3" inner diameter, roughly 3.5" long nominal but it's hard to measure the length because it varies on the inside and outside angles.

 

 

If it doesn't work out I can send you my old one, I just inspected it more thoroughly and the rubber is cracked around the clamp but nothing is actually ripped through the entire thickness, it probably has a couple years of life left in it still.

 

kks, did your hose fit? have a link for the one you got? i need both couplers. i have a stillen tube but it uses the oem couplers. wonder how long i've been sucking unfiltered air into my engine..... amazing how well it runs given how large an air leak these must be. The throttle body coupler is ripped about half way around the circumference just like the OP photo and two of the troughs in the accordion folds in the MAF coupler are cracked about 2 inches each.
