I've got about 4meters worth of 4" heat resistant hoses. There is 2 types. one of which is aluminum and another is foil with coiled wire to hold the hose open. They are multipurpose industrial hoses but in my case, i used it for my cold air intake.
set the hose facing forward and lead it all the way into a box with your air filter and there will be an increase in power and your fuel consumption will improve due to the abundance of oxygen and cold air from outside of the engine bay. Instead of your intake taking in the hot air from the enginebay, the cold air is taken from the air outside.
i'm selling these flexible hoses by the ft.
alluminum foil = rm15/ft.
alluminum ribbed = rm22/ft.
any questions about the DiY process feel free to ask.
pictures of the hoses and what i did with my car is attached.
to meet and deal please call 0176040915 (K)
thx :D
