yesterday i ordered the two parts from vauxhall
9177104 - hose piping adaptor (not sure if required or not yet)
9177099 - vectra c 2.0 diesel air intake
both of which cost me about £15 inc.vat
i have been looking over loads of diffferent forums and am still slightly unsure on the best method for fitting. many people say that it is a very tight fit.
I have already de-restricted the airbox.
My car is a 1.8 mk4 sport 3dr hatch x18xe1, anyone done the same mod any tips would be appreciated!
