What is best? Ive heard that siliconhoses fall of after abit and so on... And how much do garages take for changing all hoses?
I know a lot of people who have run good quality samco silicon hoses for years with no problems, i have samco and have run them for 8 months without hitch but your best replacement would be viton hoses they are beyond doubt the best, they have been put against factory,silicon and have won every test hands down.
IMO i would go with samco silicon as its cheap, proven and redily available.
I got a load of Viton hose from the US, check around rx7club.com there\'s probably some bulk buy happening :)
