Smile Split Intake Hose substitute

I know Stan TDI has probably fixed his hose by now but I just used the Napa replacement hose and it worked just fine. It gives a very snug fit and is flexible enough to do the job. The price is up to $23.xx with a Napa discount card compared to $99 + shipping from Impex or more from the stealer dealers. You also get 2 for the price so I have a spare when one of the hoses on another car splits.

I would have used the CarQuest hose Jetaah refers to with the exact angles on the hose but we don't have any CarQuest stores in our area.

I think I have about 2yrs. on the one I have now(at least 30k miles)-and it is kinda greasy feeling(oil seepage through rubber) now-time to put the 2nd half of original hose on.I did keep the oem hose as a backup also....

Mine is still going strong with no signs of deterioration or leakage.

You may want to consider wrapping those rubber hoses with Zip ties. The rubber once it begins to get soaked with oil from the inside gets spongy and deteriorates. They will expand easier then the boost hoses because the hose even when new is weaker then the OEM boost hoses but after being soaked in oil they get progressivly weaker. The Zip ties will help reenforce them.

I put the old OEM hose back on for the heck of it- a week or so after I did,I could hear a different noise coming fron under the hood on heavy acceleration-then I noticed the back corner of the valve cover was wet w/ oil-finally looked at it closer and the OEM hose had a split....I put the second piece I got from hose #21405 on and all is well again.

Out of curiosity, does someone have a picture of the engine showing which hose we're talking about please? I'm still new to my TDI. Thanx!!

It's the hose in the left of the picture. Runs from the lower boost tube to the intake in the A3 Jetta.

My B4 doesn't have this hose. All hard plastic tubes with rubber "joins" that are maybe 2" - 3" in length. Is this only for A3's then?

It looks identical to the hose that exits the intercooler on the B4's before it joins a hard plastic hose trending upwards (in front of the left front wheel well, underneath). One of these split open on the wagon that uses higher boost. I don't know if it's the same VW part, but the replacements shown here ought to work for either application.

Correct, A3 only for the intercooler pipe to intake hose.
