is there any "how to guides" on the forum for the fitment of the pd160 intake pipe ,part numbers and prices also would be useful . does this pipe make a lot of difference to the performance and is it essential to use it with a kn,green or jetex filter .

now worked out how to search the forums , doh . seems like its about £24 and the part numbers i've seen are for the euro spec parts which may chaff on a coolant hose ,didn't find any actual dyno figures did anybody do a dyno run ?

As for bhp - nope no difference although you can rev higher more easily so that helps
