Very tight but doable. I got the long ones first but they were too long and had to bend and didn’t look good. I would recommend.

Looks great and works great. On more garbage air and oily mess being sucked into my engine. Money well spent.

Good except for cheap plastic wye that will probably last a month or so if I am even that lucky.

works ok. a little over priced. Should send enough tubing of the right diameter to run the line to bottom of motorcycle

Breather kit

The materials are top notch; however, the elbows are 3/8" not 5/16" like the hose and the top two ins on the Y-line fitting. The Y-line fitting then goes back to 3/8" out. Doesn't make much sense and only 5/16" hose is included.
