I had a very hard time getting the tube on my intercooler (same part from RPM)Had to loosen alot to get in there so i could get it to slide on. Even used soapy water to help it slid (FINALLY GOT IT) IT WORKS GREAT zero issue after a year.
It got annoying. I ended up changing it to the medium spring. I think as it got miles on it it loosened up a little and the light spring wasn’t enough.
