Throttle body air hose

[Z71]

Today my check engine light came on for the first time in my 2013 Sonic (about 63k miles, 1.8 liter engine, 5 speed manual transmission). I pulled the code and it was P0171 - lean condition. This means there is a vacuum leak and air intake leak somewhere. i knew about some complaints about the throttle body air intake hose (from the air cleaner to throttle body). This hose is among first things I checked and sure enough the hose was almost separated in two on top. This was not something that was visible when popping the hood though. I had to place my hands on the hose and physically check it before I saw the split in the hose. I taped up the hose with tape to seal it before I can get a new hose and install it. I wonder if local dealers carry that one in stock.

This is a real problem with these engines. The hose is way too thin and eventually splits. An overly lean condition will also demonstrate itself as loss in power.

Many reports premature cracking and deterioration of factory air intake hose. This part is called an Outlet Duct by General Motors and there is a newer one made of different material.

Originally part was made of NBR/PVC - Nitrile Butadiene Rubber/PVC blend. Part # 95489808.

Replacement material is EPDM rubber Ethylene Propylene Diene Monomer Part # 94537633

Insist on the 94537633 part number or you can order it here 12-16 Chevy Sonic Genuine GM 94537633 1.8 Engine Air Cleaner Outlet Duct Hose | eBay Price is $44.50 delivered to your door

No, just the 1.8 at this time.

Seems GM has raised the price to almost double what is was to $86.99

It cost me $ 76 plus tax to buy this hose from the local GM dealer and the list price is supposedly $ 112. I was not aware of lower price on eBay.
It is not easy to install this hose as there is practically no room to tighten the lower clamp. You need a very short screwdriver (a stubby one about 1 inch long) and an open 8 mm wrench. GM dealers carry this hose in stock as it is known to fail.

An 8 mm socket, swivel, extension and ratchet make it a 5 min job..... Just a short time ago there were many places to buy then from (GM Dealers on ebay) for under $40 plus shipping... I bought mine ebay from a dealer Roger Dean Chevrolet in Florida for $44.50 delivered to the door back in the summer. I am shocked to see how much they want for the part now.

Yeah... WTF, it used to be 45 bucks... I wish there was a CARB legal CAI

There is a CARB legal CAI... cut the bottom of your air box open, replace the accordion pipe with hard pipe, go with a better panel filter. Done.

There's no giant power improvement with a CAI, it's just noisier

There should be a recall on that part! We should not have to pay to replace crappy parts.

Your warranty won't cover rubber parts after the 3/36 since they're usually considered wear items. I swapped over to an intake and don't have to worry. The hard pipe and stock airbox could be combined for a quieter solution.

It sucks they don't equip it with a better part, but at least we can fix it easily and have upgrade options

I will have to check this out. I have a freaking smog pump and I am not sure where its intake connects on the box.

Had to replace the one on our sonic about a year ago it was cracked up pretty bad.
