I am putting back my stock air filter but am confused about this hose that I am suppose to buy. The KN cold air filter has 1 rubber tube that connects from the engine to the tube. The KN rubber tube does not fit to the factory air filter tube. I was told by Honda dealer that the stock pipe has three tubes. Everytime I rev high, it smells like burnt rubber. I think its is because the KN rubber hose does not fit to the stock air filter tube.

Here is the a picture.

The tube I need to buy is part 3 (quanitity 1). They said I also need part 7 (quantity 1) with part 5 (quantity 2) as the clamps.

However, I need to figure out what clamp I need to connect B-1 of part 3 to. This is the side that connects to the stock air filter tube. I think B-1 connects here

But I cannot tell if the clamp I need is part 15 (91405-PH7-003) or part 25 which I cannot find a part number for. This site is strange, it doesnt tell you what part number 25 is and why there are two pictures of the air filter tube.

Has anyone on the forum gone from stock to KN or vice versa recently? If so, does anyone recall why there are three tubes in the stock one when the KN only has 1 tube connecting from the engine to the air filter?

yes.

The KN tube takes the place of 7,5, and the metal three tubes. The three tubes contain: 1) vacuum line (the one you need) and 2) coolant lines (x2, iirc). The KN kit comes with a tube to use in place of the coolant line section, so you really only need the vacuum line connection.

I'll check this to make sure when I go home - but I'm pretty sure my previous statement was correct. (You only need that one tube to connect to the stock elbow).
