Upgraded my filter from a cheap Spectre cone filter to a new Green Filter 2383 Green High Performance Air Filter. This is mated to a Skunk2 343-99-0500 Black 3.5″ Composite Velocity Stack and then into a 45 degree silicone hose reducer. Right now I’m still using the stock intake hose, but eventually I would like to upgrade that to a carbon fiber or aluminum intake pipe.
I am having issues with the velocity stack sliding out of the hose. No matter how tight the clamp is, it eventually works its way out. I may use 80 grit sandpaper and scuff it up a bit and see if that works.
